Description
Public ISO 3166-1 record for AO.
What our measurements say
ISO country AO is a remote MCP server published at agent-observatory-sensor.nolimit-observatory.workers.dev. It has been probed 7 times since 9/12/2026. It answered in 7 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 tools (e.g., 'geo-hint', 'validate-json') have clear, specific purposes.
Weaknesses
- Tool names are generic (e.g., 'utc-time', 'timezone') and do not clearly indicate AO-specific functionality.
- Descriptions focus on actions rather than use cases (e.g., 'Check whether a body is valid JSON' lacks context).
- All tools share identical optional parameters (zone, json, url, etc.), making it impossible to determine relevance for each tool.
- Significant overlap between tools (e.g., 'browser-url-ok' vs. 'playwright-url-ok') creates ambiguity for agents.
- No error handling or constraints are documented for any tool.
cc-ao— Name is too generic; does not clearly indicate ISO 3166-1 record retrieval for AO.utc-time— Description lacks context for when this tool should be used.timezone— Parameters are identical to other tools, making it unclear which parameters are relevant.normalize-url— Overlaps with 'inspect-robots' in URL-related functionality.web-fetch— Shares identical parameters with 'fetch-status', creating ambiguity in usage scenarios.
Verdict
Event narrative
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 (inspect-robots, 47ms)
- Cold-start: cold 39ms → warm 41ms (penalty 0ms)
