Aisotools

A hosted Model Context Protocol server over the AISOTools catalog — 1,113 AI tools with pricing, ratings, features, pros, cons, and curated alternatives.

There is nothing to install. The server is a stateless Streamable HTTP endpoint:

https://aisotools.com/api/mcp

Every result carries the canonical https://aisotools.com/tool/<slug> page for the tool, so an assistant answering "what's the best transcription API?" can cite a source rather than paraphrase from memory.

Tools

Tool	What it does
search_ai_tools	Search the catalog by keyword, category, and pricing (free/freemium/paid). Ranked summaries.
get_ai_tool	Full record for one tool — description, features, pros, cons, who it's best for, pricing tiers, alternatives. Accepts a slug or a display name.
list_ai_tool_categories	Every category with its slug, subcategories, and tool count. Use the slugs to filter search_ai_tools.
compare_ai_tools	Side-by-side comparison of 2–5 named tools. Names it can't resolve come back in an unmatched array rather than being silently dropped.
find_ai_tool_alternatives	Alternatives to a given tool. Curated alternatives and same-category fallbacks are returned in separate fields, not blended.

Read-only. No authentication, no API key, no rate-limit signup.

Notes on the data

• totalTools is 1,113 at the time of writing and moves as the catalog grows; search_ai_tools reports both matched and searched so you can see the denominator it actually searched.
• sponsored is computed against the placement's expiry, so a lapsed sponsorship reports false rather than staying flagged forever. Sponsored placement never changes search ranking.
• Ratings and review counts are catalog metadata, not live scrapes.

Protocol

Streamable HTTP, protocol version 2025-06-18. POST only — GET and DELETE answer 405 (the server is stateless, so there is no SSE stream or session to resume). Notifications answer 202 with no body. JSON-RPC batches are supported.
