Tools: list_categories search_apis get_api get_reviews
list_categories | List all categories in the catalog with the number of services in each. params: none |
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, params: query, category, mcp, no_auth, free_tier, include_trials, no_card, auth, volume, min_rating, min_reviews, min_downloads, min_issue_health, sort, limit, verbose |
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 pu params: id* |
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, lim params: id*, min_rating, max_rating, since, about_api, aspect, limit |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
