AISOTools MCP Server (io.github.shibley/aisotools)

This Model Context Protocol (MCP) server provides a hosted, stateless Streamable HTTP endpoint that lets clients search, compare, and find alternatives across the AISOTools catalog. The catalog includes 3,064 AI tools, with associated pricing, ratings, features, pros, cons, and curated alternatives.

🛠️ Key Features

Stateless Streamable HTTP endpoint
Search, compare, and find alternatives across a catalog of 3,064 AI tools

🚀 Use Cases

Retrieve catalog entries while answering questions about specific AI tools
Support responses (e.g., “best transcription API?”) with cited source URLs
Explore curated alternatives for a given tool

⚡ Developer Benefits

Canonical per-tool URLs enable source-citing rather than memory-based paraphrasing
Hosted endpoint simplifies integration (no local setup)

AISOTools MCP Server

A hosted Model Context Protocol server over the AISOTools catalog — 3,064 AI tools with pricing, ratings, features, pros, cons, and curated alternatives.

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

code

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 3,064 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.
