Sendblue Browser MCP

A standalone debug browser for agents. Stealth-patched Chromium behind a tiny HTTP API, with persistent named sessions, an easy purge endpoint, configurable auto screenshots, and CDP attach so any client (Playwright, Puppeteer, undetected-chromedriver, custom scripts) can drive it. It runs locally over stdio via the published package.

People connecting browser automation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.
