Description
Cargo.toml crate name shape, body discarded
What our measurements say
Cargo.toml crate name shape, body 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.

Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Some descriptions briefly explain purpose (e.g., 'Current UTC timestamp')
- Consistent parameter structure across all tools
Weaknesses
- Tool names are vague or non-descriptive (e.g., 'cargo-ok', 'web-fetch')
- Descriptions don't explain usage context or when to use tools
- All parameters are optional with no clear required fields
- 30+ tools show significant functional overlap (e.g., multiple URL handling tools)
- No error handling or constraint documentation
cargo-ok— Name doesn't explain purpose; description is identical to tool namenormalize-url— Shares parameters with 28 other tools without clear differentiationvalidate-json— Critical parameter 'json' is marked optional despite being core to functionagent-tool-index— Complex description lacks clear usage scenarios
