New Relic MCP Server

Instructions

Implementation Reference

• newrelic_mcp/server.py:316-327 (handler)

  MCP tool handler for 'get_application'. Decorated with @mcp.tool() which registers the tool. Executes the logic by calling the NewRelicClient.get_application method, handles errors, and returns JSON-formatted response.

  @mcp.tool()
  async def get_application(app_id: str) -> str:
      """Get details for a specific New Relic application"""
      if not client:
          return json.dumps({"error": "New Relic client not initialized"})
  
      try:
          result = await client.get_application(app_id)
          return json.dumps(result, indent=2)
      except Exception as e:
          return json.dumps({"error": str(e)}, indent=2)

• newrelic_mcp/server.py:73-76 (helper)

  Core helper method in NewRelicClient class that constructs the New Relic API URL and makes the HTTP GET request to fetch application details.

  async def get_application(self, app_id: str) -> Dict[str, Any]:
      """Get details for a specific application"""
      url = f"{self.base_url}/applications/{app_id}.json"
      return await self._make_request("GET", url)
