Kitsune MCP

Kitsune is an MCP server that allows AI coding agents like Claude Code to interact with existing Firefox, Zen, or LibreWolf browsers. It enables agents to search the web, read pages, fill forms, and take screenshots while keeping the user's sessions, cookies, and extensions intact. It operates without Playwright or WebDriver, respecting user focus and allowing configurable modes for read, draft, or act.
