New Relic MCP Server

Instructions

Implementation Reference

• newrelic_mcp/server.py:390-400 (handler)

  The MCP tool handler function for 'get_alert_policy'. It checks if the client is initialized, calls the client's get_alert_policy method, and returns the JSON-formatted result or error.

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

• newrelic_mcp/server.py:111-114 (helper)

  Helper method in the NewRelicClient class that constructs the API URL and makes the GET request to retrieve the specific alert policy details from New Relic API.

  async def get_alert_policy(self, policy_id: str) -> Dict[str, Any]:
      """Get details for a specific alert policy"""
      url = f"{self.base_url}/alerts_policies/{policy_id}.json"
      return await self._make_request("GET", url)
