Char Hero Char is an embedded AI agent that can interact with your web application. Users chat with the agent, and it uses WebMCP tools to fill forms, click buttons, read data, and navigate—all within your UI.

What Char provides

  • Embeddable agent — Drop-in web component for any framework
  • WebMCP tools — Let the agent interact with your UI
  • SSO authentication — Use your existing identity provider
  • Organization skills — Guide agent behavior with SKILL.md files
  • Cross-app tools — Access tools from multiple browser tabs and remote services

AI-Tested Tools

The AI that writes your tools also tests them. Chrome DevTools MCP lets Claude Code call the exact same WebMCP tools that your embedded agent uses. When Claude writes a tool, it tests it immediately. If Claude can’t use a tool, it fixes it—before your users ever see it.
