Description
Avro object-container magic, body discarded
What our measurements say
Avro object-container magic, body discarded is a remote MCP server published at agent-observatory-sensor.nolimit-observatory.workers.dev. It has been probed 16 times since 9/12/2026. It answered in 16 of them (100.0%), a near-uninterrupted record. Median response time is 39 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.
Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Some tool names are descriptive (e.g., 'validate-json', 'web-fetch')
- Parameters are consistently defined with 'required': false flag
Weaknesses
- Many tool names are vague (e.g., 'avro-ok', 'utc-time')
- Descriptions often repeat 'body discarded' without explaining use cases
- All parameters share identical schema across 30 tools
- No differentiation between similar tools (e.g., 'normalize-url' vs 'web-fetch')
- No error handling or constraints documented
avro-ok— Name provides no context about Avro object-container functionalityutc-time— Description lacks explanation of when/why to use this tooltimezone— Parameters include irrelevant fields like 'feed' and 'ref'inspect-robots— No clarification on when robots.txt inspection is neededagent-tool-index— Critical hop instructions buried in description
Verdict

Risk: low
Advice
Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- tools/list schema valid
- inputSchema is valid JSON Schema
- Smoke test passed · last run:
- Cold-start: cold 37ms → warm 39ms (penalty 0ms)
