Description
cid: URL shape, value discarded
What our measurements say
cid: URL shape, value discarded 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 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
- Wide range of tools covering URL parsing, time handling, and validation
- Consistent parameter structure across all tools
Weaknesses
- Tool names are often ambiguous (e.g., 'think-steps', 'calc-eval')
- Descriptions frequently omit usage context, focusing only on what they do
- All parameters are optional with no clear required/optional indicators
- Significant functional overlap between tools (e.g., 'browser-url-ok' vs 'playwright-url-ok')
- No explicit error handling or constraint documentation
