How to choose
- Free can have limits. Many free servers cap daily use, and some charge for heavier features.
- Check what you send. A free hosted server still receives your requests, so avoid sending private data.
- Expect less reliability. Free services can change or go down. Our daily check removes failing servers from this list.
How to connect one
Here is FernTool as an example. In Claude Code, run:
claude mcp add --transport http ferntool https://www.ferntool.com/mcpFor other apps, follow our guides for Claude, ChatGPT, Cursor and VS Code.
How we picked these
We read each listing's tools and put the closest fit for this job first. Hosted servers must pass a real MCP handshake in our daily check to stay on this page, and local servers are reviewed from their source or package. That shows a server responds, not how well it works for you, and we don't run every tool in production.
