MCP tool tour — true request/response pairs from 8 core tools

PASS40sprompt: enartifact: en

Prompt (verbatim)

n/a — this scenario is a deterministic stdio JSON-RPC probe, not a prompted agent session.

What happened

Deterministic stdio JSON-RPC probe: initialize -> notifications/initialized -> paginated tools/list -> 8 scripted tools/call; no LLM involved.
tools/list exposed 41 tools — all pinned core tools present (asserted against the vendored registry).
Every response below is a captured original; full pairs in capture.jsonl.
