Give Cline a browser that outlives the task.

Use Cline's built-in option when it fits

Cline already has built-in browser automation.

Cline's browser_action tool uses Puppeteer for navigation, coordinate clicks, typing, screenshots, and console capture. Its documented task lifecycle includes Automatic cleanup on task completion. For a browser that belongs to one Cline task, use the built-in tool. Official Cline browser lifecycle source ↗

Explicit Streamable HTTP setup

Connect Cline to the local Hronaut endpoint.

Start Hronaut first. In Cline's MCP panel, add a remote server, choose Streamable HTTP, and enter the endpoint. Or add the same definition through cline mcp. Set the type explicitly: Cline preserves an untyped URL as legacy SSE for backward compatibility. Official Cline MCP setup ↗

{
  "mcpServers": {
    "hronaut": {
      "type": "streamableHttp",
      "url": "http://127.0.0.1:47812/mcp",
      "disabled": false,
      "autoApprove": []
    }
  }
}

Verify before using a login

Prove the connection in an isolated Hronaut workspace.

1. 1

   Confirm the server

   Open Cline's MCP Servers panel, or run cline config mcp --json, and confirm hronaut is enabled. The interactive manager is cline mcp.

2. 2

   Keep approval on

   Leave MCP auto-approval disabled until the server and tool list match what you expect.

3. 3

   Create a clean first workspace

   Ask: “Create a Hronaut workspace named first-check, open https://example.com inside it, and tell me the page title and workspace ID. Do not use my Default workspace.”

4. 4

   Confirm the observable result

   A separate visible first-check workspace opens Example Domain, and Cline reports its stable workspace ID.
