Prerequisites

​
Node.js

You need to have Node.js installed to use the Browser MCP server.

​
Add MCP server

Add the MCP server config to an AI application that supports MCP. Example applications that support MCP:
  1. Open full Cursor settings
  2. Navigate to the “Tools” tab
  3. Click “New MCP server”
  4. Add the server config below
  5. Click the refresh button next to the “browsermcp” server to reload the server config
For more information, see Cursor’s MCP documentation.
See Claude’s MCP documentation
Claude Desktop currently has a bug where MCP servers are started twice. This will cause Claude to show an error when using the Browser MCP server but it will still work.
