- May 7, 2026description
This extension brings the power of the Model Context Protocol to everyday users by exposing extension apis as tools for the chat agent in the side bar. It also comes with two proprietary transports that allow the side bar model to interact with MCP servers declared in the tabs javascript. It also acts as a bridge which connects the extension to local chat clients like cursor and Claude desktop.
