MCP servers.
Connect a server the community built.
An MCP server is a program somebody else built that gives your AI new tools: search a service, read a file, call an API.
Connect one here and Claude, Claude Code, ChatGPT, Codex and Cursor all reach it through a single endpoint, with your key held on the server side.

What is an MCP server?
The Model Context Protocol is the open standard AI clients use to call tools. An MCP server is a program that answers those calls: it publishes a few tools with their inputs, and the AI decides when to use them. Most are written by the people who needed them and published as open source, which is why this list is long and uneven.
8,894 of the 12,806 servers listed here can be served through ahel today. The rest stay listed so you can find them and read what they do, and their pages say plainly that ahel cannot serve them yet.
Connect one to Claude, Cursor, Codex or ChatGPT
Connecting a server here does not put anything on your machine. ahel runs it and serves its tools to every AI client you sign in with, so one connection covers Claude, Claude Code, ChatGPT, Codex, Cursor and VS Code with Copilot.
Your client's tool list stays the same size whatever you connect: a server's own tools are read with the tools verb and run with the use verb. Keys are sealed in ahel and injected server side, so a credential never crosses the link.
