Each tool supports multiple output formats and filtering options. Available as an open-source npm package, the server connects to the Datadog API using your API and application keys. Datadog also offers official MCP Server documentation and LLM Observability features that trace MCP client calls with structured metadata about invoked tools, parameters, and responses.
