Claude Code populates the deferred tools list at session initialization from the MCP server's tools/list response — When /mcp reconnect is called mid-session. Tension: the deferred tools index in the session context is not re-populated — it retains the snapshot from session start. Outcome: any tools added to the server after the session began are invisible to ToolSearch regardless of reconnects.
