Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names like 'access_check_url' clearly indicate their purpose.
- Descriptions provide technical context about web crawling rules and access checks.
Weaknesses
- Descriptions are overly technical and lack user-focused guidance on when to use tools.
- Two tools (access_explain_verdicts, access_list_agents) have missing parameter definitions.
- No error handling or constraint documentation in any tool descriptions.

Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
access_check_urlGiven a URL, say whether an AI agent may fetch it, on what terms, and at what price. Reads robots.txt for a generic agent and for every AI user-agent the operators document, the Content-signal and Content-Usage directives, any RSL licence the origin links, and the live response to an honestly-identified request. Verdicts: `allowed` (it served us), `allowed_if_identified` (the written policy permits this but bot management refused an anonymous request — signing as a named crawler is the documented route), `charged` (there is a price, quoted where the rail will show one), `blocked` (the site disallows the agents that would want this, with nothing to buy), and `unknown` (the origin did not answer, or the URL is not there). Never evades: no CAPTCHA solving, no proxies, no spoofed user-agents

access_explain_verdictsReturn the five verdicts this index can return, what each one means for an agent that has just been refused, and what the agent's next move is for each. Costs nothing and makes no request; call it once to interpret access_check_url results.
access_list_agentsReturn the AI crawler tokens this index reads robots.txt rules for — only tokens their operators document — plus the widely-written tokens that no operator sends, which make a robots rule unenforceable. Useful when writing or auditing a robots.txt.

- Free Google Flights MCPserver.smithery.ai
Free real-time Google Flights search — one-way and round-trip — with no API key and no signup. ### What it returns - Live fares with airline, stops, duration and a bookable link - **Google's own price insights** (`price_insights_low` / `price_insights_high`) plus a low / typical / high verdict, so an agent can tell the user whether a fare is actually a good deal — most flight APIs don't expose this at all - Round-trip priced as **paired legs**, not two one-ways stitched together ### Flexible dates in a single call Pass a departure date range and/or several destinations, and the server fans out internally and merges the results. *"Cheapest flight to Sri Lanka anywhere in October"* is **one** tool call, not thirty. Every response carries `search_coverage` stating exactly which dates were searched, so a sampled scan is never mistaken for an exhaustive one. ### Tools | Tool | What it does | | --- | --- | | `search_oneway_flights` | One-way search — a single date, or a date range | |
