Honeycomb's hosted MCP server lets AI agents query observability data, fetch traces, explore the service map, manage Boards and Triggers, check SLOs and launch Canvas investigations. Most tools are read-only; writes require the mcp:write scope. It uses OAuth by default, with Management API key auth for unattended agents, and has US and EU endpoints.
