Cline

Cline adds remote MCP servers through its UI or through the MCP settings JSON.

Add Through The UI

In the Cline panel, click the MCP Servers icon in the top toolbar, open the Remote Servers tab, then enter:

Field	Value
Server Name	dagu
Server URL	$DAGU_MCP_URL
Transport Type	Streamable HTTP

Click Add Server.

Configuration

Configure MCP Servers opens the MCP settings JSON used by the extension. The Cline CLI reads ~/.cline/mcp.json.

{
  "mcpServers": {
    "dagu": {
      "type": "streamableHttp",
      "url": "http://localhost:8080/mcp",
      "headers": {
        "Authorization": "Bearer dagu_..."
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}

Set "type": "streamableHttp" explicitly. Omitting type falls back to the legacy SSE transport, which Dagu does not serve.

autoApprove lists tools Cline may call without asking. Leave it empty, or limit it to dagu_read so that workflow edits and run control still require confirmation.

The key is stored literally in the settings file. Use a key scoped to the mcp surface with the narrowest role that fits the work, described in Authentication.

Verify

Reopen the MCP Servers panel and confirm dagu is connected and that dagu_read, dagu_change, and dagu_execute are listed.
