Data quality — please read

some tools return a login wall instead of a pricing page, and the extractor can't always tell "free tier needs no card" from "paid plans need a card".

• The directory is reliable. Name, URL, department, pricing tier, description and tags are human-maintained and reviewed.
• freeTier is NOT verified. It is regex-extracted from vendor pages and has known failure modes:

auto-detected and may be outdated.

• The server drops contradictory signals rather than guessing.
• The server's instructions require any assistant using freeTier to tell the user it is

• Coverage is ~87% of tools reachable; of those, about half yielded a usable signal.
• A missing freeTier field means "no data", not "no free tier."

If you find wrong free-tier data, please open an issue — that's exactly the feedback needed to improve the extractor.

Self-host

The server is a single Cloudflare Worker with no dependencies.

npm install
node build-dataset.mjs          # regenerate dataset.json (edit it, or point it at your own data)
npx wrangler deploy

Requires CLOUDFLAREACCOUNTID and CLOUDFLAREAPITOKEN in the environment — do not commit them.

node test.mjs https://ai-tools-mcp.toolboxes.top   # 36 end-to-end assertions

To run locally:

npx wrangler dev --port 8791
node test.mjs http://127.0.0.1:8791

Notes on the deployment

ai-tools-mcp.toolboxes.top (a Cloudflare custom domain on the Worker).

• workers.dev hostnames are blocked by the GFW, so the canonical hostname is

• The endpoint is served directly from a Worker; there is no origin server.
