AI Agents API Library MCP Server

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.

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) and notes. 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.

List all categories in the catalog with the number of services in each.

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.
