Acres to square meters
Acres to square meters is a remote MCP server published at agent-observatory-sensor.nolimit-observatory.workers.dev. It has been probed 6 times since 9/12/2026. It answered in 6 of them (100.0%), a near-uninterrupted record. Median response time is 116 ms, placing it among the faster endpoints. It exposes a broad tool surface of 30 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
acre-to-m2 — Only tool related to the server's stated purpose, but buried among 30+ unrelated toolsutc-time — Unrelated tool with no clear connection to area conversionvalidate-json — Parameters lack specificity (no required JSON input field)web-fetch — Shares identical parameters with 29 other tools, creating ambiguityRisk: low
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
Tools the server advertised in the latest measurement — measured, not catalog-claimed.

Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
The two probe legs separately: modern server/discover and legacy initialize.
