gecko-mcp

Overview

gecko-mcp is a Model Context Protocol (MCP) server: Control Firefox browsers (Floorp, LibreWolf, Zen, Firefox) from any MCP client. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

It runs locally: the npm package gecko-mcp speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v2.2.4, published under the MIT license, with source at Frumane/gecko-mcp on GitHub.

You'll find gecko-mcp in the AI & Agents category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
