Connector Details

This MCP server provides AI assistants with access to the browser's tab management, browsing history, page search, and webpage text content through a local MCP (Model Context Protocol) connection. Before accessing any webpage content, explicit user consent is required for each domain through browser-side permissions. **Note:** This extension requires a separate Firefox add-on component, which is available at [https://addons.mozilla.org/en-US/firefox/addon/browser-control-mcp/](https://addons.mozilla.org/en-US/firefox/addon/browser-control-mcp/). Start by installing the Firefox add-on, then copy the secret key from the add-on settings page (it will open automatically) and paste it into this extension's configuration.
