Usage
Add MCP Browser Kit to your MCP Client:
{ "mcpServers": { "browser-kit": { "command": "npx", "args": ["@mcp-browser-kit/server@latest"] } } }By default the server use
stdiotransport, alternatively you can usehttptransport:npx @mcp-browser-kit/server@latest --transport http # optional flags (defaults shown): # --http-host 127.0.0.1 # --http-port 21082Then point your MCP client at the URL instead of a
command:{ "mcpServers": { "browser-kit": { "url": "http://127.0.0.1:21082/mcp" } } }Security: there's no auth yet, so
--http-hostdefaults to127.0.0.1(loopback only). Only pass--http-host 0.0.0.0(or a LAN address) if you understand that anyone who can reach that host/port can control your browser.Choose the right extension build for your browser:
