Tools of AI Agents API Library
	Description		Read-only	Idempotent	Open world
`get_api`Full entry for one service: docs, auth scheme and how the credential is sent, base URL, operations, MCP endpoint or repository (a repository must be installed; a docs-only server does not call the API), free plan vs trial, rate limits, data policy, notes, last-checked dates, link check, and separate signals: uptime (our availability probes of base URL and MCP endpoint), mcp_repo (archived, last push), mcp_registry (installs), product_reviews (rating, count, date range), sdk_downloads (official npm/PyPI SDKs per month), stackoverflow (question count), app_store (the vendor's iOS app) and github_issues (open vs resolved issues, median days to fix and issue_health 0-100 of the SDK, MCP and spec repos), each with its fetch date. Values carry the vendor page they were read from and a check date.

Values carry the vendor page they were read from and a check date.	No	Yes	Yes	No
`get_reviews`Public user reviews of one service (up to 100, from SourceForge): rating, title, pros, cons, overall, reviewer role, company size, date and link to the original. Reviewer names are not included. Reviews do not show whether the API fits the task. Each review has aspect tags; `topics` counts them with example links. Filter with since, max_rating (complaints) or about_api (API, reliability, auth, limits, breaking changes, docs). Review titles and texts are written by third parties.

`search_apis`Search 300+ catalog entries of third-party APIs and MCP servers (each with a last-checked date) by operation or keywords, with optional category and quality filters. `match`: exact = the entry lists the operation and its example call or an MCP tool performs it; listed = the entry lists it without that evidence; adjacent = a related operation; topic = word match only. Exact is still a search label, not proof that the endpoint or tool accepts the user's actual inputs. `mcp_fit` says whether the MCP server has a tool for the operation. Ranking weighs operation fit, evidence, lasting free plan, card and auth effort, and bulk limits, not budget or region: read free_plan.kind (free_tier lasts, trial is one-off), no_card, unit_price and notes (coverage, coordinate systems, bulk and trial restrictions). Ratings and the MCP client config come with verbose=true or from get_api. User opinions (SourceForge product reviews): filter with min_rating / min_reviews, order with sort=rating or sort=reviews; results with stored review texts carry reviews_summary (praised and complained-about aspects). Usage: ratings.usage gives monthly downloads of the official SDKs, Stack Overflow questions and the vendor's iOS app rating; filter with min_downloads, order with sort=usage. Maintenance: ratings.issues gives the vendor's GitHub issues (share resolved, median days to fix, issue_health 0-100); filter with min_issue_health, order with sort=issues. Reviews rate the product, not whether the API fits the task. An empty result means no catalogued fit for the query and filters.
