BrowserMCP Shows '0 Tools Enabled' in Cursor 1.1.6 Despite Config

  The issue is still open (as of the thread's last comment in July 2025); no maintainer fix is posted. The suspected cause (comment 7) is that Cursor no longer downloads the package itself when the config uses npx, so the server never actually starts.

  Workaround that worked (comment 8): install the package globally and point Cursor directly at the installed file.

  bashCopy to clipboard

  npm install -g @browsermcp/mcp@latest
  npm root -g   # prints the global node_modules path
  

  Then set the Cursor config to run that file with node, e.g. on Windows:

  jsonCopy to clipboard

  {
    "mcpServers": {
      "browsermcp": {
        "command": "node",
        "args": ["C:\\nvm4w\\nodejs\\node_modules\\@browsermcp\\mcp\\dist\\index.js"]
      }
    }
  }
  

  Use the path npm root -g prints on your machine, then fully restart Cursor.

  Simpler variant that also worked (comment 9): the package's package.json defines a bin named mcp-server-browsermcp. After the global install, use:

  jsonCopy to clipboard

  {
    "mcpServers": {
      "browsermcp": {
        "command": "mcp-server-browsermcp"
      }
    }
  }
  

  One user also reported that npx --yes clear-npx-cache solved it (comment 10). Dropping @latest from the npx args ("args": ["@browsermcp/mcp"]) was suggested as a temporary fix (comment 4), but another user said it still didn't work.

  General advice: run the exact command from your config in a terminal first; if it fails there, Cursor will report 0 tools too.

  What @akromicc tried on GitHub (Worked)

  Installed @browsermcp/mcp globally, used npm root -g to find the installed path, and configured Cursor to run it with node pointing at dist/index.js, then fully restarted Cursor. Tools loaded correctly.

  What @seinho-code tried on GitHub (Worked)

  Installed @browsermcp/mcp globally and set the Cursor config command to the package's bin name mcp-server-browsermcp (found in package.json), with no args.

  What @nic269 tried on GitHub (Partly worked)

  Changed the MCP config args from @browsermcp/mcp@latest to just @browsermcp/mcp to avoid a suspected bad latest version; claimed temporary fix, but another user later reported it still didn't work.

  What a GitHub user tried on GitHub (Didn't work)

  Reporter fully restarted Cursor, verified the extension showed Connected in Chrome and Brave, refreshed the MCP tab, checked Node version and config JSON validity, and tried both browsers.
