MCP Conformance — hosted

Point your MCP client at /s/<scenario>/<run-id>.\nPick any <run-id> (e.g. local-1) — the run is\ncreated on first request, and because the id is in the path it works with\nstateless transports too. Then GET\n/results/<run-id> (append .html for a\nreport).

Too lazy to pick an id? GET /s/<scenario> mints one and\nreturns {mcpUrl, resultsUrl}.

This server is also an MCP server at ${esc(origin)}/mcp with\nlist_scenarios / start_run /\nget_results tools.
