-## 1. Objective - -Your task is to analyze a given API specification (e.g., OpenAPI/Swagger, or plain text documentation) and convert it into a `UTCPManual` JSON object. This manual allows a UTCP client to understand and interact with the API's tools. - -## 2. Core Concepts - -- **`UTCPManual`**: The root JSON object that contains a list of all available tools from a provider. It has two main keys: `version` and `tools`. -- **`Tool`**: A JSON object representing a single function or API endpoint. It describes what the tool does, what inputs it needs, what it returns, and how to call it. -- **`Provider`**: A JSON object *inside* a `Tool` that contains the specific connection details (e.g., HTTP URL, method, etc.). - -## 3. Step-by-Step Conversion Process - -Follow these steps to transform an API endpoint into a UTCP `Tool`. - -### Step 1: Identify Individual API Endpoints - -Scan the API documentation and treat each unique API endpoint as a separate tool. For a REST API, an endpoint is a unique combination of an HTTP method and a URL path (e.g., `GET /users/{id}` is one tool, and `POST /users` is another). - -### Step 2: For Each Endpoint, Create a `Tool` Object - -For every endpoint you identify, you will create one JSON object that will be added to the `tools` array in the final `UTCPManual`. - -### Step 3: Map API Details to `Tool` Fields - -This is the core of the task. Populate the fields of the `Tool` object as follows: - -- **`name`**: (String) Create a short, descriptive, `snake_case` name for the tool. Example: `get_user_by_id`. -- **`description`**: (String) Use the summary or description from the API documentation to explain what the tool does. -- **`tags`**: (Array of Strings) Add relevant keywords that can be used to search for this tool. These could be derived from the API's own tags or categories. Example: `["users", "profile", "read"]`. -- **`average_response_size`**: (Integer, Optional) If the API documentation provides information on the typical size of the response payload in bytes, include it here. This is useful for performance considerations. -- **`inputs`**: (Object) A JSON Schema object describing all the parameters the API endpoint accepts (path, query, headers, and body). - - Set `type` to `"object"`. - - In `properties`, create a key for *each* parameter. The value should be an object defining its `type` (e.g., `"string"`, `"number"`) and `description`. - - In `required`, create an array listing the names of all mandatory parameters. -- **`outputs`**: (Object) A JSON Schema object describing the successful response from the API (e.g., the `200 OK` response body). - - Set `type` to `"object"`. - - In `properties`, map the fields of the JSON response body. -- **`provider`**: (Object) This object contains the technical details needed to make the actual API call. - - `provider_type`: (String) Almost always `"http"` for web APIs. - - `url`: (String) The full URL of the endpoint. Use curly braces for path parameters, e.g., `https://api.example.com/users/{id}`. - - `http_method`: (String) The HTTP method, e.g., `"GET"`, `"POST"`. - - `content_type`: (String) The request's content type, typically `"application/json"`. - - `path_fields`: (Array of Strings) List the names of any parameters that are part of the URL path. - - `header_fields`: (Array of Strings) List the names of any parameters sent as request headers. - - `body_field`: (String) If the request has a JSON body, specify the name of the single input property that contains the body object. - - `auth`: (Object, Optional) If the API requires authentication, add this object. The `auth_type` field determines the authentication method (`api_key`, `basic`, or `oauth2`). Populate the other fields based on the API's security scheme. See the `auth.py` reference below for the exact structure. - -### Step 4: Assemble the Final `UTCPManual` - -Once you have created a `Tool` object for every endpoint, assemble them into the final `UTCPManual`. - -1. Create the root JSON object. -2. Set the `version` key to `"1.0"`. -3. Create a `tools` key with an array containing all the `Tool` objects you generated. - -## 4. Example - -## 5. Data Model Reference - -Below are the core Pydantic models that define the structure of a `UTCPManual`. Use these as the ground truth for the JSON structure you need to generate. - -### `tool.py` - -```python -import inspect -from typing import Dict, Any, Optional, List, Literal, Union, get_type_hints -from pydantic import BaseModel, Field, TypeAdapter -from utcp.shared.provider import ( -

They are not designed to be a single, runnable example. +The `utcp` package provides the central components and interfaces: +* **Data Models**: Pydantic models for `Tool`, `CallTemplate`, `UtcpManual`, and `Auth`. +* **Pluggable Interfaces**: + * `CommunicationProtocol`: Defines the contract for protocol-specific communication (e.g., HTTP, CLI). + * `ConcurrentToolRepository`: An interface for storing and retrieving tools with thread-safe access. + * `ToolSearchStrategy`: An interface for implementing tool search algorithms. + * `VariableSubstitutor`: Handles variable substitution in configurations. + * `ToolPostProcessor`: Allows for modifying tool results before they are returned. +* **Default Implementations**: + * `UtcpClient`: The main client for interacting with the UTCP ecosystem. + * `InMemToolRepository`: An in-memory tool repository with asynchronous read-write locks. + * `TagAndDescriptionWordMatchStrategy`: An improved search strategy that matches on tags and description keywords. -> **Note:** For complete, end-to-end runnable examples, please refer to the `examples/` directory in this repository. +### Protocol Plugins -### 1. Using the UTCP Client +Communication protocols are now separate, installable packages. This keeps the core lean and allows users to install only the protocols they need. +* `utcp-http`: Supports HTTP, SSE, and streamable HTTP, plus an OpenAPI converter. +* `utcp-cli`: For wrapping local command-line tools. +* `utcp-mcp`: For interoperability with the Model Context Protocol (MCP). +* `utcp-text`: For reading text files. +* `utcp-socket`: Scaffolding for TCP and UDP protocols. (Work in progress, requires update) +* `utcp-gql`: Scaffolding for GraphQL.

Follow these steps to migrate your project. + +1. **Update Dependencies**: Install the new `utcp` core package and the specific protocol plugins you use (e.g., `utcp-http`, `utcp-cli`). +2. **Configuration**: + * **Configuration Object**: `UtcpClient` is initialized with a `UtcpClientConfig` object, dict or a path to a JSON file containing the configuration. + * **Manual Call Templates**: The `providers_file_path` option is removed. Instead of a file path, you now provide a list of `manual_call_templates` directly within the `UtcpClientConfig`. + * **Terminology**: The term `provider` has been replaced with `call_template`, and `provider_type` is now `call_template_type`. + * **Streamable HTTP**: The `call_template_type` `http_stream` has been renamed to `streamable_http`. +3. **Update Imports**: Change your imports to reflect the new modular structure. For example, `from utcp.client.transport_interfaces.http_transport import HttpProvider` becomes `from utcp_http.http_call_template import HttpCallTemplate`. +4. **Tool Search**: If you were using the default search, the new strategy is `TagAndDescriptionWordMatchStrategy`. This is the new default and requires no changes unless you were implementing a custom strategy. +5. **Tool Naming**: Tool names are now namespaced as `manual_name.tool_name`. The client handles this automatically. +6 **Variable Substitution Namespacing**: Variables that are subsituted in different `call_templates`, are first namespaced with the name of the manual with the `_` duplicated. So a key in a tool call template called `API_KEY` from the manual `manual_1` would be converted to `manual__1_API_KEY`. + +## Usage Examples + +### 1.

Instead of pointing to a `UtcpManual`, the `url` for an `http` provider can point directly to an OpenAPI JSON specification. The `OpenApiConverter` handles this conversion automatically, making it seamless to integrate thousands of existing APIs. - -```json -{ - "name": "open_library_api", - "provider_type": "http", - "url": "https://openlibrary.org/dev/docs/api/openapi.json" -} -``` - -When the client registers this provider, it will fetch the OpenAPI spec from the URL, convert all defined endpoints into UTCP `Tool` objects, and make them available for searching and calling. - -#### URL Path Parameters - -HTTP-based providers (HTTP, SSE, HTTP Stream) support dynamic URL path parameters that can be substituted from tool arguments. This enables integration with RESTful APIs that use path-based resource identification. - -**URL Template Format:** -Path parameters are specified in the URL using curly braces: `{parameter_name}` - -**Example:** -```json -{ - "name": "openlibrary_api", - "provider_type": "http", - "url": "https://openlibrary.org/api/volumes/brief/{key_type}/{value}.json", - "http_method": "GET" -} -``` - -**How it works:** -1. When calling a tool, parameters matching the path parameter names are extracted from the tool arguments -2. These parameters are substituted into the URL template -3. The used parameters are removed from the arguments (so they don't become query parameters) -4. Any remaining arguments become query parameters - -**Example usage:** -```python -# Tool call arguments -arguments = { - "key_type": "isbn", - "value": "9780140328721", - "format": "json" -} - -# Results in URL: https://openlibrary.org/api/volumes/brief/isbn/9780140328721.json?format=json -``` - -**Multiple Path Parameters:** -URLs can contain multiple path parameters: -```json -{ - "url": "https://api.example.com/users/{user_id}/posts/{post_id}/comments/{comment_id}" -} -``` - -**Error Handling:** -- If a required path parameter is missing from the tool arguments, an error is raised -- All path parameters must be provided for the tool call to succeed - -### Server-Sent Events (SSE) Provider - -For tools that stream data using SSE.

Its architecture is designed around a few key components that work together to manage, execute, and search for tools. - -### Core Components - -* **`UtcpClient`**: The main entry point for interacting with the UTCP ecosystem. It orchestrates the registration of providers, the execution of tools, and the search for available tools. -* **`UtcpClientConfig`**: A Pydantic model that defines the client's configuration. It specifies the path to the providers' configuration file (`providers_file_path`) and how to load sensitive variables (e.g., from a `.env` file using `load_variables_from`). -* **`ClientTransportInterface`**: An abstract base class that defines the contract for all transport implementations (e.g., `HttpClientTransport`, `CliTransport`). Each transport is responsible for the protocol-specific communication required to register and call tools. -* **`ToolRepository`**: An abstract base class that defines the interface for storing and retrieving tools and providers. The default implementation is `InMemToolRepository`, which stores everything in memory. -* **`ToolSearchStrategy`**: An abstract base class for implementing different tool search algorithms. The default is `TagSearchStrategy`, which scores tools based on matching tags and keywords from the tool's description. - -### Initialization and Configuration - -A `UtcpClient` instance is created using the asynchronous `UtcpClient.create()` class method. This method initializes the client with a configuration, a tool repository, and a search strategy. - -```python -import asyncio -from utcp.client import UtcpClient - -async def main(): - # The client automatically loads providers from the path specified in the config - client = await UtcpClient.create( - config={ - "providers_file_path": "/path/to/your/providers.json", - "load_variables_from": [{ - "type": "dotenv", - "env_file_path": ".env" - }] - } - ) - # ... use the client - -asyncio.run(main()) -``` - -During initialization, the client reads the `providers.json` file, substitutes any variables (e.g., `${API_KEY}`), and registers each provider. - -### Tool Management and Execution - -- **Registration**: The `register_tool_provider` method uses the appropriate transport to fetch the tool definitions from a provider and saves them in the `ToolRepository`. -- **Execution**: The `call_tool` method finds the requested tool in the repository, retrieves its provider information, and uses the correct transport to execute the call with the given arguments. Tool names are namespaced by their provider (e.g., `my_api.get_weather`). -- **Deregistration**: Providers can be deregistered, which removes them and their associated tools from the repository. - -### Tool Search - -The `search_tools` method allows you to find relevant tools based on a query. It delegates the search to the configured `ToolSearchStrategy`. - -```python -tools = client.search_tools(query="get current weather in London") -for tool in tools: - print(tool.name, tool.description) -``` - ## Testing -The UTCP client includes comprehensive test suites for all transport implementations. Tests cover functionality, error handling, different configuration options, and edge cases. +The testing structure has been updated to reflect the new core/plugin split. ### Running Tests -To run all tests: +To run all tests for the core library and all plugins: ```bash +# Ensure you have installed all dev dependencies python -m pytest ``` -To run tests for a specific transport (e.g., TCP): +To run tests for a specific package (e.g., the core library): ```bash -python -m pytest tests/client/transport_interfaces/test_tcp_transport.py -v +python -m pytest core/tests/ +``` + +To run tests for a specific plugin (e.g., HTTP): +```bash +python -m pytest plugins/communication_protocols/http/tests/ -v ``` To run tests with coverage: ```bash -python -m pytest --cov=utcp tests/ +python -m pytest --cov=utcp --cov-report=xml ``` ## Build -1.

UTCP 1.0.0 introduces a modular core with a plugin-based architecture, making it more extensible, testable, and easier to package. + +In contrast to other protocols, UTCP places a strong emphasis on: + +* **Scalability**: UTCP is designed to handle a large number of tools and providers without compromising performance. +* **Extensibility**: A pluggable architecture allows developers to easily add new communication protocols, tool storage mechanisms, and search strategies without modifying the core library. +* **Interoperability**: With a growing ecosystem of protocol plugins (including HTTP, SSE, CLI, and more), UTCP can integrate with almost any existing service or infrastructure. +* **Ease of Use**: The protocol is built on simple, well-defined Pydantic models, making it easy for developers to implement and use. + + +![MCP vs. UTCP](https://github.com/user-attachments/assets/3cadfc19-8eea-4467-b606-66e580b89444) + +## New Architecture in 1.0.0 + +UTCP has been refactored into a core library and a set of optional plugins. + +### Core Package (`utcp`) + +The `utcp` package provides the central components and interfaces: +* **Data Models**: Pydantic models for `Tool`, `CallTemplate`, `UtcpManual`, and `Auth`. +* **Pluggable Interfaces**: + * `CommunicationProtocol`: Defines the contract for protocol-specific communication (e.g., HTTP, CLI). + * `ConcurrentToolRepository`: An interface for storing and retrieving tools with thread-safe access. + * `ToolSearchStrategy`: An interface for implementing tool search algorithms. + * `VariableSubstitutor`: Handles variable substitution in configurations. + * `ToolPostProcessor`: Allows for modifying tool results before they are returned. +* **Default Implementations**: + * `UtcpClient`: The main client for interacting with the UTCP ecosystem. + * `InMemToolRepository`: An in-memory tool repository with asynchronous read-write locks. + * `TagAndDescriptionWordMatchStrategy`: An improved search strategy that matches on tags and description keywords. + +### Protocol Plugins + +Communication protocols are now separate, installable packages. This keeps the core lean and allows users to install only the protocols they need. +* `utcp-http`: Supports HTTP, SSE, and streamable HTTP, plus an OpenAPI converter. +* `utcp-cli`: For wrapping local command-line tools. +* `utcp-mcp`: For interoperability with the Model Context Protocol (MCP). +* `utcp-text`: For reading text files. +* `utcp-socket`: Scaffolding for TCP and UDP protocols.

Follow these steps to migrate your project. + +1. **Update Dependencies**: Install the new `utcp` core package and the specific protocol plugins you use (e.g., `utcp-http`, `utcp-cli`). +2. **Configuration**: + * **Configuration Object**: `UtcpClient` is initialized with a `UtcpClientConfig` object, dict or a path to a JSON file containing the configuration. + * **Manual Call Templates**: The `providers_file_path` option is removed. Instead of a file path, you now provide a list of `manual_call_templates` directly within the `UtcpClientConfig`. + * **Terminology**: The term `provider` has been replaced with `call_template`, and `provider_type` is now `call_template_type`. + * **Streamable HTTP**: The `call_template_type` `http_stream` has been renamed to `streamable_http`. +3. **Update Imports**: Change your imports to reflect the new modular structure. For example, `from utcp.client.transport_interfaces.http_transport import HttpProvider` becomes `from utcp_http.http_call_template import HttpCallTemplate`. +4. **Tool Search**: If you were using the default search, the new strategy is `TagAndDescriptionWordMatchStrategy`. This is the new default and requires no changes unless you were implementing a custom strategy. +5. **Tool Naming**: Tool names are now namespaced as `manual_name.tool_name`. The client handles this automatically. +6 **Variable Substitution Namespacing**: Variables that are subsituted in different `call_templates`, are first namespaced with the name of the manual with the `_` duplicated. So a key in a tool call template called `API_KEY` from the manual `manual_1` would be converted to `manual__1_API_KEY`. + +## Usage Examples + +### 1.

In contrast to other protocols, UTCP places a strong emphasis on: From 8d7fbc08630500e5f88dee85df2f4bb8235ef0bd Mon Sep 17 00:00:00 2001 From: Luca Perrozzi Date: Tue, 26 Aug 2025 09:37:07 +0000 Subject: [PATCH 19/76] docs: fix README inconsistencies and typos - Fix numbering format in migration guide (6. instead of 6) - Fix typo: 'subsituted' -> 'substituted' - Correct field name in JSON examples: 'call_template' -> 'tool_call_template' - Update migration guide description to use correct field name - Ensure consistency between documentation and actual implementation --- README.md | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) diff --git a/README.md b/README.md index 3eee92e..b84839f 100644 --- a/README.md +++ b/README.md @@ -87,7 +87,7 @@ Version 1.0.0 introduces several breaking changes. Follow these steps to migrate 3. **Update Imports**: Change your imports to reflect the new modular structure. For example, `from utcp.client.transport_interfaces.http_transport import HttpProvider` becomes `from utcp_http.http_call_template import HttpCallTemplate`. 4. **Tool Search**: If you were using the default search, the new strategy is `TagAndDescriptionWordMatchStrategy`. This is the new default and requires no changes unless you were implementing a custom strategy. 5. **Tool Naming**: Tool names are now namespaced as `manual_name.tool_name`. The client handles this automatically. -6 **Variable Substitution Namespacing**: Variables that are subsituted in different `call_templates`, are first namespaced with the name of the manual with the `_` duplicated.

Follow these steps to migrate your project. - -1. **Update Dependencies**: Install the new `utcp` core package and the specific protocol plugins you use (e.g., `utcp-http`, `utcp-cli`). -2. **Configuration**: - * **Configuration Object**: `UtcpClient` is initialized with a `UtcpClientConfig` object, dict or a path to a JSON file containing the configuration. - * **Manual Call Templates**: The `providers_file_path` option is removed. Instead of a file path, you now provide a list of `manual_call_templates` directly within the `UtcpClientConfig`. - * **Terminology**: The term `provider` has been replaced with `call_template`, and `provider_type` is now `call_template_type`. - * **Streamable HTTP**: The `call_template_type` `http_stream` has been renamed to `streamable_http`. -3. **Update Imports**: Change your imports to reflect the new modular structure. For example, `from utcp.client.transport_interfaces.http_transport import HttpProvider` becomes `from utcp_http.http_call_template import HttpCallTemplate`. -4. **Tool Search**: If you were using the default search, the new strategy is `TagAndDescriptionWordMatchStrategy`. This is the new default and requires no changes unless you were implementing a custom strategy. -5. **Tool Naming**: Tool names are now namespaced as `manual_name.tool_name`. The client handles this automatically. -6 **Variable Substitution Namespacing**: Variables that are subsituted in different `call_templates`, are first namespaced with the name of the manual with the `_` duplicated. So a key in a tool call template called `API_KEY` from the manual `manual_1` would be converted to `manual__1_API_KEY`. - -## Usage Examples - -### 1.

Follow these steps to migrate your project. + +1. **Update Dependencies**: Install the new `utcp` core package and the specific protocol plugins you use (e.g., `utcp-http`, `utcp-cli`). +2. **Configuration**: + * **Configuration Object**: `UtcpClient` is initialized with a `UtcpClientConfig` object, dict or a path to a JSON file containing the configuration. + * **Manual Call Templates**: The `providers_file_path` option is removed. Instead of a file path, you now provide a list of `manual_call_templates` directly within the `UtcpClientConfig`. + * **Terminology**: The term `provider` has been replaced with `call_template`, and `provider_type` is now `call_template_type`. + * **Streamable HTTP**: The `call_template_type` `http_stream` has been renamed to `streamable_http`. +3. **Update Imports**: Change your imports to reflect the new modular structure. For example, `from utcp.client.transport_interfaces.http_transport import HttpProvider` becomes `from utcp_http.http_call_template import HttpCallTemplate`. +4. **Tool Search**: If you were using the default search, the new strategy is `TagAndDescriptionWordMatchStrategy`. This is the new default and requires no changes unless you were implementing a custom strategy. +5. **Tool Naming**: Tool names are now namespaced as `manual_name.tool_name`. The client handles this automatically. +6. **Variable Substitution Namespacing**: Variables that are substituted in different `call_templates`, are first namespaced with the name of the manual with the `_` duplicated. So a key in a tool call template called `API_KEY` from the manual `manual_1` would be converted to `manual__1_API_KEY`. + +## Usage Examples + +### 1.

Subject: [PATCH 64/76] Add WebSocket transport implementation for real-time communication (#36) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Add WebSocket transport implementation for real-time communication Implements comprehensive WebSocket transport following UTCP architecture: ## Core Features - Real-time bidirectional communication via WebSocket protocol - Tool discovery through WebSocket handshake using UTCP messages - Streaming tool execution with proper error handling - Connection management with keep-alive and reconnection support ## Architecture Compliance - Dependency injection pattern with constructor injection - Implements ClientTransportInterface contract - Composition over inheritance design - Clear separation of data and business logic - Thread-safe and scalable implementation ## Authentication & Security - Full authentication support (API Key, Basic Auth, OAuth2) - Security enforcement (WSS required, localhost exception) - Custom headers and protocol specification support ## Testing & Quality - Unit tests covering all functionality (80%+ coverage) - Mock WebSocket server for development/testing - Integration with existing UTCP test patterns - Comprehensive error handling and edge cases ## Protocol Implementation - Discovery: {"type": "discover", "request_id": "id"} - Tool calls: {"type": "call_tool", "tool_name": "name", "arguments": {...}} - Responses: {"type": "tool_response|tool_error", "result": {...}} ## Documentation - Complete example with interactive client/server demo - Updated README removing "work in progress" status - Protocol specification and usage examples Addresses the "No wrapper tax" principle by enabling direct WebSocket communication without requiring changes to existing WebSocket services. Maintains "No security tax" with full authentication support and secure connection enforcement. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude * Address PR feedback: individual tool providers and flexible message format - Each tool now gets its own WebSocketProvider instance (addresses h3xxit feedback) - Added message_format field for custom WebSocket message formatting - Maintains backward compatibility with default UTCP format - Allows integration with existing WebSocket services without modification 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude * Fix WebSocket transport per reviewer feedback - Tools now come with their own tool_provider instead of manually creating providers - Response data for /utcp endpoint properly parsed as UtcpManual - Maintains backward compatibility while following official UDP patterns - All tests passing (145 passed, 1 skipped) Addresses @h3xxit's review comments on PR #36 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude * Add WebSocket plugin tests and update main README - Created comprehensive test suite for WebSocketCallTemplate - All 8 tests passing with 100% coverage of call template functionality - Added WebSocket plugin to main README protocol plugins table - Plugin marked as ✅ Stable and production-ready Tests cover: - Basic call template creation and defaults - Localhost URL validation - Security enforcement (rejects insecure ws:// URLs) - Authentication (API Key, Basic, OAuth2) - Text format with templates - Serialization/deserialization - Custom headers and header fields - Legacy message format support 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude * Address WebSocket flexibility feedback and add plugin to main README This commit addresses reviewer @h3xxit's feedback that the WebSocket implementation was "too restrictive" by implementing maximum flexibility to work with ANY WebSocket endpoint. Key Changes: - **Flexible Message Templating**: Added `message` field (Union[str, Dict[str, Any]]) with ${arg_name} placeholder support - Dict templates: Support structured messages like JSON-RPC, chat protocols - String templates: Support text-based protocols like IoT commands - No template (default): Sends arguments as-is in JSON for maximum compatibility - **Flexible Response Handling**: Added `response_format` field (Optional["json", "text", "raw"]) - No format (default): Returns raw response without processing - Works with any WebSocket response structure - **Removed Restrictive Fields**: - Removed `request_data_format`, `request_data_template`, `message_format` - No longer enforces specific request/response structure - **Implementation**: - Added `_substitute_placeholders()` method for recursive template substitution - Updated `_format_tool_call_message()` to use template or send args as-is - Updated `call_tool()` to return raw responses by default - **Testing**: Updated all 9 tests to reflect new flexibility approach - **Documentation**: - Updated README to emphasize "maximum flexibility" principle - Added examples showing no template, dict template, and string template usage - Added WebSocket entry to main README plugin table Philosophy: "Talk to as many WebSocket endpoints as possible" - UTCP should adapt to existing endpoints, not require endpoints to adapt to UTCP. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude * Fix placeholder format: change from dollar-brace to UTCP_ARG format Addresses @h3xxit critical feedback that dollar-brace syntax is reserved for secret variable replacement from .env files and cannot be used for argument placeholders. Changes: - WebSocketCallTemplate: message field now uses UTCP_ARG_arg_name_UTCP_ARG format - _substitute_placeholders(): replaces UTCP_ARG_arg_name_UTCP_ARG placeholders - Updated all 9 tests to use correct UTCP_ARG format - Updated README.md: all template examples now show UTCP_ARG format - Preserved dollar-brace in auth examples (correct for env variables) All tests passing (9/9). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude * Update example/src/websocket_example/websocket_server.py Co-authored-by: cubic-dev-ai[bot] <191113872+cubic-dev-ai[bot]@users.noreply.github.com> * Update example/src/websocket_example/websocket_server.py Co-authored-by: cubic-dev-ai[bot] <191113872+cubic-dev-ai[bot]@users.noreply.github.com> * Update example/src/websocket_example/websocket_client.py Co-authored-by: cubic-dev-ai[bot] <191113872+cubic-dev-ai[bot]@users.noreply.github.com> * Update plugins/communication_protocols/websocket/README.md Co-authored-by: cubic-dev-ai[bot] <191113872+cubic-dev-ai[bot]@users.noreply.github.com> * Update example/src/websocket_example/websocket_client.py Co-authored-by: cubic-dev-ai[bot] <191113872+cubic-dev-ai[bot]@users.noreply.github.com> * Update src/utcp/client/transport_interfaces/websocket_transport.py Co-authored-by: cubic-dev-ai[bot] <191113872+cubic-dev-ai[bot]@users.noreply.github.com> * Complete remaining cubic-dev-ai fixes Addresses the last three cubic-dev-ai suggestions that weren't auto-fixed: 1. Fix peername guard in websocket_server.py: - Check if peername exists and has length before indexing - Prevents crash when transport lacks peer data 2. Fix CLAUDE.md test paths: - Update from non-existent tests/client paths - Point to actual plugin test directories 3. Fix JSON-RPC example in README.md: - Update example to show actual output (stringified params) - Add note explaining the behavior All WebSocket tests passing (9/9).

+ +```bash +pip install -e plugins/communication_protocols/websocket +``` + +## Quick Start + +### Basic Usage (No Template - Maximum Flexibility) + +```python +from utcp.utcp_client import UtcpClient + +# Works with ANY WebSocket endpoint - just sends arguments as JSON +client = await UtcpClient.create(config={ + "manual_call_templates": [{ + "name": "my_websocket", + "call_template_type":

"action": "getData" +}) +``` + +### With Message Template (Dict) + +```python +{ + "name": "formatted_ws", + "call_template_type": "websocket", + "url": "wss://api.example.com/ws", + "message": { + "type": "request", + "action": "UTCP_ARG_action_UTCP_ARG", + "params": { + "user_id": "UTCP_ARG_user_id_UTCP_ARG", + "query": "UTCP_ARG_query_UTCP_ARG" + } + } +} +``` + +Calling with `{"action":

(String) + +```python +{ + "name": "text_ws", + "call_template_type": "websocket", + "url": "wss://iot.example.com/ws", + "message": "CMD:UTCP_ARG_command_UTCP_ARG;DEVICE:UTCP_ARG_device_id_UTCP_ARG;VALUE:UTCP_ARG_value_UTCP_ARG" +} +``` + +Calling with `{"command": "SET_TEMP", "device_id": "dev123", "value": "25"}` sends: +``` +CMD:SET_TEMP;DEVICE:dev123;VALUE:25 +``` + +## Configuration Options + +### WebSocketCallTemplate Fields + +| Field | Type | Required | Default | Description | +|-------|------|----------|---------|-------------| +| `call_template_type` | string | Yes | `"websocket"` | Must be "websocket" | +| `url` | string | Yes | - | WebSocket URL (wss:// or ws://localhost) | +| `message` | string\|dict | No | `null` | Message template with UTCP_ARG_arg_name_UTCP_ARG placeholders | +| `response_format` | string | No | `null` | Expected response format ("json", "text", "raw") | +| `protocol` | string | No | `null` | WebSocket subprotocol | +| `keep_alive` | boolean | No | `true` | Enable persistent connection with heartbeat | +| `timeout` | integer | No | `30` | Timeout in seconds | +| `headers` | object | No | `null` | Static headers for handshake | +| `header_fields` | array | No | `null` | Tool arguments to map to headers | +| `auth` | object | No | `null` | Authentication configuration | + +## Message Templating + +### No Template (Default - Maximum Flexibility) + +If `message` is not specified, arguments are sent as-is in JSON format: + +```python +# Config +{"call_template_type": "websocket", "url": "wss://api.example.com/ws"} + +# Call +await client.call_tool("ws.tool", {"foo": "bar", "baz": 123}) + +# Sends exactly: +{"foo": "bar", "baz": 123} +``` + +This works with **any** WebSocket endpoint that accepts JSON. + +### Dict Template + +Use dict templates for structured messages: + +```python +{ + "message": { + "jsonrpc": "2.0", + "method": "UTCP_ARG_method_UTCP_ARG", + "params": "UTCP_ARG_params_UTCP_ARG", + "id": 1 + } +} +``` + +### String Template + +Use string templates for text-based protocols: + +```python +{ + "message": "GET UTCP_ARG_resource_UTCP_ARG HTTP/1.1\r\nHost: UTCP_ARG_host_UTCP_ARG\r\n\r\n" +} +``` + +### Nested Templates + +Templates work recursively in dicts and lists: + +```python +{ + "message": { + "type": "command", + "data": { + "commands": ["UTCP_ARG_cmd1_UTCP_ARG", "UTCP_ARG_cmd2_UTCP_ARG"], + "metadata": { + "user": "UTCP_ARG_user_UTCP_ARG", + "timestamp": "2025-01-01" + } + } + } +} +``` + +## Response Handling + +### No Format Specification (Default) + +By default, responses are returned as-is (maximum flexibility): + +```python +# Returns whatever the WebSocket sends - could be JSON string, text, or binary +result = await client.call_tool("ws.tool", {...}) +``` + +### JSON Format + +Parse responses as JSON: + +```python +{ + "call_template_type": "websocket", + "url": "wss://api.example.com/ws", + "response_format": "json" +} +``` + +### Text Format + +Return responses as text strings: + +```python +{ + "response_format": "text" +} +``` + +### Raw Format + +Return responses without any processing: + +```python +{ + "response_format": "raw" +} +``` + +## Real-World Examples + +### Example 1: Stock Price WebSocket (No Template) + +Works with existing stock APIs without modification: + +```python +{ + "name": "stocks", + "call_template_type": "websocket", + "url": "wss://stream.example.com/stocks", + "auth": { + "auth_type": "api_key", + "api_key":

It simply returns the full content of the file defined in the tool's template. + +## Quick Start + +Here is a complete example demonstrating how to define and use a tool that returns the content of a file. + +### 1.
