Exploring MCP sessions

An MCP session is one agent run: the set of $mcp_tool_call events sharing a $session_id, ordered by timestamp.

Listing sessions, reading a session's tool calls, and summarising its goal each have a typed tool — reach for those first. Drop to HogQL only for the three things the typed tools genuinely can't do (see When to drop to SQL). The full $mcp_* property schema and query recipes live in the shared reference: models-mcp.md.
