Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- Tool list unreadable — the server responds, but its tools/list call does not return a valid result. Schema checks and AI evaluation cannot run.
- inputSchema invalid: —
- Smoke test not run this round
- Cold-start: cold 4ms → warm 5ms (penalty 0ms)
Availability history
Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Era history
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
Response time history
The two probe legs separately: modern server/discover and legacy initialize.
Event log
Derived by comparing consecutive probes — changes in era, protocol version, build and reachability.
