Open-source AI browser with MCP support
SafeCoBrowser is an open-source AI co-browsing browser for macOS that lets you bring Claude Code, Codex, or any MCP agent into your logged-in browser — only when you allow it, per tab, with an instant kill switch and a full audit log.
Overview
SafeCoBrowser is an open-source AI co-browsing browser for macOS that lets you bring Claude Code, Codex, or any MCP agent into your logged-in browser — only when you allow it, per tab, with an instant kill switch and a full audit log. It exposes a local MCP server (Streamable HTTP with a bearer token) and a CLI over the same permission broker, so any MCP-compatible agent can connect.
MCP + CLI
Every capability is a brokered tool surfaced over both MCP and the CLI. Agents get read tools (read page, screenshot, inspect, console/network), and — only when you grant them — act tools (click, fill) and a separate Developer grant for running JavaScript. Recipes are agent-readable as how-tos.
Open source
SafeCoBrowser is open source under AGPL-3.0. Source and issues: https://github.com/corleylun/flowbrowse.
