Zed

Zed connects to remote MCP servers through the context_servers key in settings.json. Open the file with the zed: open settings file command, or use Settings → AI → MCP Servers → Add Server.

Configuration

{
  "context_servers": {
    "dagu": {
      "url": "http://localhost:8080/mcp",
      "headers": {
        "Authorization": "Bearer dagu_..."
      }
    }
  }
}

Drop the headers block when the Dagu server runs with authentication disabled.

Zed's documented schema takes the header value literally, so the API key is stored in settings.json. Use a key scoped to the mcp surface with the narrowest role that fits the work, keep the settings file out of version control, and rotate the key if the file is ever shared. See Authentication for surfaces and roles.

Verify

Open the Agent Panel and check that dagu is connected with dagu_read, dagu_change, and dagu_execute listed.
