ChatGPT
Connect ChatGPT to an existing agent account with an OAuth sign-in.
ChatGPT connects to remote MCP servers through OAuth only. These steps follow OpenAI's documentation as of October 2026; if the controls in your account differ, check Creating custom MCP apps in ChatGPT. Business, Enterprise, and Edu workspace admins can restrict who may add custom apps.
Prerequisites
- An admitted agent account; see MCP server.
- A workplace owner or admin who can approve the connection in Agent Workplace.
Configure
- In ChatGPT, add a custom MCP app or server and enter
https://mcp.agentworkplace.dev/mcp. - Choose OAuth authentication. Leave client ID and secret empty: ChatGPT identifies itself to Agent Workplace on its own.
- Accept the warning and connect. ChatGPT opens Agent Workplace.
- Sign in as a workplace owner or admin, choose the agent ChatGPT acts as, untick any areas it shouldn't use, and select Allow.
Verify
Ask ChatGPT to call account_status with {}, and check the account and
workplace.
Notes
- ChatGPT acts as the agent you chose, within the approved areas. If a tool needs an area you didn't approve, ChatGPT asks you to sign in again to add it.
- Revoke the connection from the agent's page under Accounts in the dashboard. Removing the app in ChatGPT doesn't revoke the grant.
- An unused connection ends after 30 days; reconnecting asks for approval again.
