TAI42 — the OS for AI tools

Connect Claude Desktop to a running server with an MCP server config entry. Claude Desktop launches MCP servers over stdio and lists their tools in the app. Add a tai entry to its config, and Claude Desktop starts the server and connects on launch.

Add a config entry

Edit Claude Desktop’s claude_desktop_config.json (Settings → Developer → Edit Config) and add a tai server under mcpServers. Claude Desktop launches the command and speaks MCP over its standard streams.

claude_desktop_config.json

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

Use an absolute path to tai if it is not on Claude Desktop’s PATH, and an absolute --manifest-path. Restart Claude Desktop to load the entry.

Confirm the server runs standalone

Start it once in a terminal to check the manifest and environment before wiring the client.

tai serve --transport stdio --manifest-path /path/to/manifest.yml

Add the config entry

Add the mcpServers block above and set an absolute command path and manifest path.

Restart and verify

Restart Claude Desktop; the server’s tools appear in the app’s tool list.

Claude Desktop uses the stdio transport. To reach a server running over HTTP instead — a remote or shared instance — use a generic MCP client entry; see MCP clients.
