TAI42 — the OS for AI tools

Connect Cursor to a running server with an MCP server config entry. Cursor reads MCP servers from an mcp.json file and lists their tools in the editor. Add a tai entry — a launch command for a stdio server, or a URL for an HTTP one.

Add a config entry

Put the entry in ~/.cursor/mcp.json for all projects, or .cursor/mcp.json in a project for that project only. Add a tai server under mcpServers.

{
  "mcpServers": {
    "tai": {
      "command": "tai",
      "args": ["serve", "--transport", "stdio", "--manifest-path", "/path/to/manifest.yml"]
    }
  }
}

{
  "mcpServers": {
    "tai": {
      "url": "http://localhost:8000/mcp"
    }
  }
}

Use an absolute path to tai and to the manifest for the stdio entry. For the HTTP entry, run the server yourself (tai serve --transport http --port 8000) and point the URL at it.

A server behind access control requires an API key. For the stdio entry, set TAI_API_KEY in an env block on the server; for the HTTP entry, supply it in the client’s request headers.
