"""Server-side Datadog tools backed by Datadog's hosted MCP server.
|
||
|
|
|
||
|
|
Credentials live in team settings (encrypted at rest) and are attached as
|
||
|
|
``DD_API_KEY`` / ``DD_APPLICATION_KEY`` headers to the MCP connection, which runs
|
||
|
|
in the LangGraph server process. The sandbox never holds Datadog credentials.
|
||
|
|
|
||
|
|
The default toolset is ``core`` (query-oriented: logs, metrics, traces,
|
||
|
|
dashboards, monitors, incidents, hosts, services, events). Override via
|
||
|
|
``DATADOG_MCP_TOOLSETS``.
