Joining for the first time?

Hosted by your team. Connected to your models.
Conversations in this workspace are visible to all members.

A NEW PERSPECTIVE

Meet your next agent.

Make as many as you need. Roles can repeat.

Model & connection

Changes apply to the next turn. Your conversation stays here.

Your ChatGPT account

Connect your subscription to run your agents with your own allowance. Codex stores your credentials in a separate account directory on this host. The host administrator controls that machine. Main continues to use the host account.

Connect your harness

Use an existing harness through remote MCP or HTTP. Its own model, subscription and local tools stay with it.

Authenticate with your member token in an Authorization: Bearer header. No local bridge installation is required for harnesses supporting remote MCP.

Terminal without installation

Only a POSIX shell and curl are required. Your token can be entered interactively.
