Connect ChatGPT and Claude

ChatGPT and Claude use the same public MCP endpoint:

https://your-app-origin/mcp

Use the App URL printed by deploy/jio.sh, not the landing or docs URL. Open the app first, register an account, and create or select a project.

ChatGPT

1. Open Settings → Apps. Workspace administrators may instead use Workspace settings → Apps.
2. Enable developer mode if your plan or workspace requires it, then choose Create.
3. Enter the public /mcp URL and select OAuth authentication.
4. Leave custom client credentials empty, scan the tools, and create the app.
5. Complete sign-in and approve a project. In a new chat, enable the app and ask it to call get_random_number.

If the tool is missing after a deployment, refresh the app's actions. Availability and administrator controls vary by plan; see OpenAI's current developer mode guide.

Claude

1. Open Customize → Connectors, choose +, then Add custom connector. Team and Enterprise owners can add it for the organization under Organization settings → Connectors.
2. Enter a name and the public /mcp URL.
3. Leave the optional OAuth client ID and secret empty, add the connector, then choose Connect.
4. Complete sign-in and approve a project. In a chat, choose + → Connectors, enable it, and ask it to call get_random_number.

See Claude's current remote connector guide if the menu location differs for your plan.

Quick check

Before configuring either client, verify that discovery is public:

curl -fsS https://your-app-origin/.well-known/oauth-protected-resource

The response should name https://your-app-origin/mcp as its resource. A direct unauthenticated request to /mcp returning 401 Unauthorized is expected: the client uses that challenge to start OAuth.
