Agent readability score
Strengths

Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
search_lessonsSearch the AI School curriculum (500+ tracks, thousands of free lessons on AI engineering, governance, security, and applied AI by profession). Returns matching lesson titles and URLs. Use this before answering an AI-topic question when a concrete, citable lesson would help, then read_lesson to get the text.
querystringrequiredlimitinteger
list_tracksList AI School course tracks, optionally filtered by a substring of the title or slug. Each track is a structured course on one subject. Use this to find the right course before drilling into its lessons.
filterstringlimitinteger
get_trackGet one track with its full lesson list, so you can see the structure of a course and pick the right lesson to read.
slugstringrequired
read_lessonFetch the full text of a lesson by its URL (as returned by search_lessons or get_track). Returns readable markdown-ish text with headings and code blocks.

- 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 | |
