AIProfile

Appearance

ChatGPT And Codex ​

ChatGPT Web Or Desktop Connector ​

ChatGPT connects from OpenAI infrastructure, so a local localhost URL is not reachable. For local desktop hosting, expose AIProfile with ngrok:

For a full visual walkthrough using npx, ChatGPT Developer Mode, and a synthetic company profile, see ChatGPT App With ngrok: npx and a Company Profile.

bash
ngrok http 3000

Configure config.yaml with the public URL and restart AIProfile:

yaml
auth:
  mode: local
  anonymous_enabled: true
  issuer: https://abc123.ngrok-free.app
  resource: https://abc123.ngrok-free.app/mcp

Create a grant:

bash
npm run auth -- grant add \
  --subject chatgpt-owner \
  --preset owner-full \
  --resource https://abc123.ngrok-free.app/mcp

In ChatGPT, add an MCP server or connector with:

text
https://abc123.ngrok-free.app/mcp

ChatGPT discovers OAuth metadata, registers itself, and opens the AIProfile authorization page. Enter the one-time approval code printed by the grant command.

Codex Terminal Or CLI ​

For terminal clients running on the same machine, use the local URL:

text
http://localhost:3000/mcp

Create a local grant:

bash
npm run auth -- grant add --subject codex-cli --preset owner-full

When Codex opens the OAuth authorization page, enter the printed one-time approval code. If your Codex environment runs remotely, use the ngrok flow above instead of localhost.
