FSB Overview

fullselfbrowsing/FSB connects MCP clients to a signed-in Chrome session through a Chrome extension and local MCP server. It reads the live DOM, selectors, ARIA data, and forms instead of relying on screenshots, then executes browser actions, verifies results, waits for page changes, and reports progress. MCP use does not require an FSB API key because the connected client provides the model reasoning. Reach for it when supervised research, testing, form entry, page inspection, or browser-based developer workflows need access to an existing Chrome session.

Primary Use Cases for FSB:
  • Run repeatable QA and regression flows
  • Research pages and summarize visible information
  • Fill structured forms and browser-based data-entry workflows
  • Compare products and monitor availability under supervision
