Description
China Air Quality MCP — nationwide hourly AQI from CNEMC (中国环境监测总站).
What our measurements say
China Air Quality is a remote MCP server published at gateway.pipeworx.io. It has been probed 12 times since 9/12/2026. It answered in 12 of them (100.0%), a near-uninterrupted record. Median response time is 46 ms, placing it among the faster endpoints. Its tool list could not be read; the server is closed to direct calls. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.

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 not measurable (no handshake)
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.
