Implementation Reference

• newrelic_mcp/server.py:717-734 (registration)

  MCP tool registration and handler for 'delete_log_parsing_rule'. Validates inputs, initializes client/account, calls core delete function from log_parsing module, and formats response as JSON.

  @mcp.tool()
  async def delete_log_parsing_rule(
      rule_id: str, account_id: Optional[str] = None
  ) -> str:
      """Delete a log parsing rule"""
      if not client:
          return json.dumps({"error": "New Relic client not initialized"})
  
      acct_id = account_id or client.account_id
      if not acct_id:
          return json.dumps({"error": "Account ID required but not provided"})
  
      try:
          success = await log_parsing.delete_log_parsing_rule(client, acct_id, rule_id)
          return json.dumps({"success": success}, indent=2)
      except Exception as e:
          return json.dumps({"error": str(e)}, indent=2)

• newrelic_mcp/log_parsing.py:520-544 (handler)

  Core handler function that executes the GraphQL mutation to delete the specified log parsing rule using the New Relic NerdGraph API.

  async def delete_log_parsing_rule(client, account_id: str, rule_id: str) -> bool:
      """Delete a log parsing rule"""
      mutation = f"""
      mutation {{
          logConfigurationsDeleteParsingRule(
              accountId: {int(account_id)},
              id: "{rule_id}"
          ) {{
              errors {{
                  message
                  type
              }}
          }}
      }}
      """
  
      result = await client.nerdgraph_query(mutation)
  
      if result and "data" in result:
          delete_result = result["data"].get("logConfigurationsDeleteParsingRule", {})
          if delete_result.get("errors"):
              raise Exception(f"Failed to delete rule: {delete_result['errors']}")
          return True
  
      return False
