Summary

Add Claude Code plugin configuration to enable this MCP server as a Claude Code plugin.

Closes #315

Changes

• Add .claude-plugin/plugin.json with plugin metadata
• Add .claude-plugin/install-binary.sh for automatic binary installation
• Plugin automatically downloads and extracts the correct binary for user's OS/architecture
• Supports Linux (x86_64, arm64, i386), macOS (x86_64, arm64), and Windows (x86_64, arm64, i386)
• Version pinned to v0.7.6

How it works

The install script:

1. Detects user's OS (Darwin/Linux/Windows) and architecture (x86_64/arm64/i386)
2. Downloads the appropriate archive (tar.gz or zip) from GitHub releases
3. Extracts the binary to the plugin directory
4. Caches the binary and only re-downloads if version changes

Installation

Users can add this plugin via a marketplace:

{
  "plugins": [
    {
      "name": "grafana",
      "description": "A Model Context Protocol (MCP) server for Grafana",
      "source": {
        "source": "github",
        "repo": "grafana/mcp-grafana"
      }
    }
  ]
}

Then install via:

/plugin install grafana@your-marketplace

The plugin will automatically download and configure the mcp-grafana binary on first use.

Platform Support

Testing

The install script has been designed to work with Grafana's release format:

• macOS/Linux: mcp-grafana_${OS}_${ARCH}.tar.gz containing mcp-grafana binary
• Windows: mcp-grafana_${OS}_${ARCH}.zip containing mcp-grafana.exe binary
