@lffrom0303 try Cursor Settings->MCP-> Click on "Add new global MCP Server"-> add the following to mcp.json:

{
    "mcpServers": {
      "browser-tools": {
        "command": "npx",
        "args": [
          "@agentdeskai/[email protected]"
        ]
      }
    }
}

Click refresh button until it's green. Open Output panel in Cursor CMD+Shift+P "output". Change dropdown to "Cursor MCP". Check if there's any specific errors in there for browsertools. Also use npx @agentdeskai/[email protected]. Open the MCP tab in Devtools and ensure the connection was successful.

I have connections issue as well using brave I see the errors on the console.
My understanding is that the server is in the browser extension?

Same issue here, not working. My development env is in WSL and my chrome is on the windows machine so i wonder if this is causing an issue

Same here, was working fine last week and just noticed this same error today with the extension. LOVE this tool, hoping it can be fixed.
