Summary

Extend MCP Node to detect MCP server configurations from multiple AI coding tools (Copilot, Codex), similar to the Skills detection implemented in #508.

Background

Currently, MCP Node only reads MCP server configurations from Claude Code paths:

• <workspace>/.mcp.json (project)
• ~/.mcp.json (user)
• ~/.claude.json (legacy)

According to AI Coding Tools Configuration Reference, other AI tools also have MCP configurations:

Proposed Changes

1. Backend: Extend MCP Config Reader

File: src/extension/services/mcp-config-reader.ts

• Add reading from Copilot paths:
  • ./.vscode/mcp.json (project, servers key)
  • ~/.copilot/mcp-config.json (user)
• Add reading from Codex path:
  • ~/.codex/config.toml (user, TOML format)
• Add source field to McpServerConfig ('claude' | 'copilot' | 'codex')
• Normalize different key names (servers → mcpServers)

2. Frontend: Grouped UI with Jump Navigation

File: src/webview/src/components/dialogs/McpNodeDialog.tsx (or related MCP UI)

Similar to SkillBrowserDialog (#508):

• Group MCP servers by source (Claude Code / Copilot / Codex)
• Add jump navigation buttons when multiple sources exist
• Display section headers with AIProviderBadge

3. Type Updates

File: src/shared/types/mcp-node.ts

interface McpServerReference {
  // ... existing fields
  source?: 'claude' | 'copilot' | 'codex';
}

Implementation Notes

JSON Key Differences

// Claude Code / Copilot CLI
{ "mcpServers": { ... } }

// VSCode Copilot
{ "servers": { ... } }

Codex TOML Format

[mcp_servers.server-name]
enabled = true
command = "npx"
args = ["-y", "package-name"]

Will need a TOML parser (e.g., @iarna/toml or smol-toml).

Acceptance Criteria

• MCP servers from Copilot paths are detected
• MCP servers from Codex path are detected (TOML parsing)
• Each server includes source field
• UI groups servers by source with jump navigation
• Backward compatible (servers without source treated as claude)
