Browser Use (MCP mode) not working in Cursor? Fixes

Date tested: Oct 13, 2026 · From our harness, not the maker’s claims · How we test

1. Use the install config we tested in Cursor

{
 "mcpServers": {
  "browser-use": {
   "command": "uvx",
   "args": [
    "--from",
    "browser-use[cli]",
    "browser-use",
    "--mcp"
   ]
  }
 }
}

Replace any <YOUR_…> placeholder and local test paths with your own. Every client’s tested snippet is on the Browser Use (MCP mode) page.

2. Check that Cursor connects to it

In our run the connect check was OK (connect time not recorded). Our check output:

browser-use: ready

3. Confirm the tools are visible

Cursor listed 16 tools from this server in our run (the protocol check found 16). Fewer or none usually means the server did not start; check the config above.

Errors we observed

agent task: click reveal: answer missing ['TP-4242']; no tool result containing ['TP-4242']
