## Overview
MCP-B is a company that maintains the reference implementation of the W3C WebMCP standard and builds tools for deploying browser-based agents. The platform enables websites to publish tools that AI agents can call, maintaining the browser's existing authentication and user interface. MCP-B offers the Char agent platform (currently in alpha), which allows organizations to deploy personalized company agents directly in the browser. The company also provides consulting services for organizations deploying browser-based agents.
