Common IANA timezone names for clock calls.
What our measurements say
IANA Zones is a remote MCP server published at agent-observatory-sensor.nolimit-observatory.workers.dev. It has been probed 13 times since 9/12/2026. It answered in 13 of them (100.0%), a near-uninterrupted record. Median response time is 37 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
- Broad range of tools covering timezones, URL validation, JSON checks, and more.
Weaknesses
- Tool names are vague or overlapping (e.g., 'iana-zones' appears twice).
- Descriptions focus on what the tool does, not when/why to use it.
- All tools share identical optional parameters with no context on relevance.
- No documentation of error cases, constraints, or usage limitations.
iana-zones— Duplicate tool name appears twice in the list.timezone— Parameter 'zone' is ambiguous without context on expected format.validate-json— No explanation of what happens if JSON validation fails.normalize-url— Parameters 'query' and 'ref' are not explained in the description.
