Implementation Reference

• newrelic_mcp/server.py:507-531 (handler)

  MCP tool handler function that implements the 'create_deployment' tool. It builds the deployment dictionary from parameters and delegates to the NewRelicClient helper method.

  @mcp.tool()
  async def create_deployment(
      app_id: str,
      revision: str,
      description: Optional[str] = None,
      user: Optional[str] = None,
      changelog: Optional[str] = None,
  ) -> str:
      """Record a new deployment for an application"""
      if not client:
          return json.dumps({"error": "New Relic client not initialized"})
  
      try:
          deployment = {"revision": revision}
          if description:
              deployment["description"] = description
          if user:
              deployment["user"] = user
          if changelog:
              deployment["changelog"] = changelog
  
          result = await client.create_deployment(app_id, deployment)
          return json.dumps(result, indent=2)
      except Exception as e:
          return json.dumps({"error": str(e)}, indent=2)

• newrelic_mcp/server.py:151-156 (helper)

  Supporting utility method in the NewRelicClient class that performs the actual HTTP POST request to the New Relic API to create a deployment.

  async def create_deployment(
      self, app_id: str, deployment: Dict[str, Any]
  ) -> Dict[str, Any]:
      """Record a new deployment for an application"""
      url = f"{self.base_url}/applications/{app_id}/deployments.json"
      return await self._make_request("POST", url, json={"deployment": deployment})
