Usage with Claude Desktop

Add to your claude_desktop_config.json:

{

      "command": "npx",
      "args": ["-y", "@raygun.io/mcp-server-raygun"],
      "env": {
        "RAYGUN_PAT_TOKEN": "your-pat-token-here"
      }
    }
  }
}

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Installation

To use with Claude Desktop, add the server config: On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "raygun": {
      "command": "/path/to/server-raygun/build/index.js",
      "env": {
        "RAYGUN_PAT_TOKEN": "your-pat-token-here"
      }
    }
  }
}

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
