Tampermonkey Mcp

Bridges your AI assistant directly to the Tampermonkey browser extension so you can read, list, and modify userscripts through natural language. After installing the Tampermonkey Editors extension, you call get-connection-code to establish a local WebSocket connection, then use list to see all your scripts, get to read their contents, and patch to modify them. The authentication flow uses connection codes derived from the WebSocket port plus tokens for security. Reach for this when you want to iterate on userscripts conversationally instead of manually editing them in the browser, or when you need to programmatically manage a collection of scripts. Works with both Firefox and Chrome through their respective Tampermonkey Editors extensions.
