Connect an agent by signing in

You can connect an agent tool that speaks Model Context Protocol (MCP), so it can read and change your loops. Any workspace member can connect one. The agent acts as you, with your access and nothing more.

Signing in is the recommended way for Claude Code, Codex and Claude on the web. For Cursor, OpenCode and other tools, see Connect with an API key. For Claude on the web, see Connect Claude on the web.
