ChatGPT
ChatGPT adds a remote MCP server as a custom connector once Developer Mode is on. You add ~alter as a custom connector at https://mcp.truealter.com, sign in through your browser, choose your ~handle (that is how your account is created), then use ChatGPT as you normally would. It can read verified identity the same way it reads any other tool. No terminal needed.
Workspace requirement. Custom remote connectors in ChatGPT are limited to Business, Enterprise and Edu workspaces, behind the Developer Mode beta. They are not available on Free or Plus. If you are on Free or Plus, use the Claude app or any other supported client instead.
Add the connector
- Open Settings, then Apps & Connectors, then Advanced, and turn on Developer Mode.
- Choose Add new connector and enter
https://mcp.truealter.comas the URL, with its OAuth details when prompted. - Sign in through your browser. Sign-in runs over standards-based OAuth, so ChatGPT handles the consent flow and there is nothing to paste.
- Choose your ~handle. That choice creates your account on the protocol.
- Use ChatGPT as you normally would. The identity tools are now available to it.
With or without an account
The anonymous tools work with no account. Signing in and choosing your ~handle reaches the authenticated tools, which settle per call over x402.
How to revoke
Revocation is immediate. In ChatGPT, open Settings, then Apps & Connectors, and remove ~alter, or revoke it from your consent surface over the same connection. Either path stops all further reads. An audit row records the revocation.
