YetiBrowser
Empowers Model Context Protocol clients to automate real browser tabs securely and locally using Node.js and dedicated browser extensions.
About
YetiBrowser is an entirely open-source implementation of the Browser MCP workflow, designed to bridge Model Context Protocol clients like Codex, Claude Code, Cursor, or your own custom tools with actual browser tabs. It ensures all data remains local and auditable by linking a Node-based MCP server with dedicated Chrome and Firefox extensions. This transparent, local-first, and cross-browser solution offers robust developer-focused tooling, including rich console capture, DOM diffing, full-page screenshots, and page-state dumps, making it ideal for debugging, QA, and production-friendly integration with IDEs.
