Description
AT Protocol DID shape, value discarded
What our measurements say
AT Protocol DID shape, value discarded 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 40 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 have descriptive names (e.g., 'validate-json', 'normalize-url')
- Consistent parameter structure across all tools
Weaknesses
- Many tool names are vague or non-descriptive (e.g., 'at-did', 'agent-tool-index')
- Descriptions often repeat the same generic text without explaining use cases
- All parameters are optional with no clear required fields
- Significant tool overlap (e.g., multiple URL validation tools)
- No error handling or constraint documentation
at-did— Name and description are identical to server name, providing no contextutc-time— Description doesn't explain when to use ittimezone— Shares same parameters as other tools without differentiationvalidate-json— Discards input but doesn't explain validation criteriaagent-tool-index— Overly complex description with unclear purpose
