Connecting to ChatGPT

MCP (Model Context Protocol) is how ChatGPT discovers and runs your app’s tools. Every Chippy app gets its own MCP endpoint: no server setup, no deployment pipeline. You copy a URL and paste it into ChatGPT.

Your App’s MCP URL

Every app gets its own MCP endpoint:

https://{slug}.preview.chippy.build/mcp

Replace {slug} with your app’s slug. You can find it in App Settings > General in the builder.

Connect ChatGPT to Your App

Find your MCP URL

Open your app in the Chippy builder. Go to App Settings and copy the MCP URL. Start with the preview URL while you’re still iterating.

Paste your URL

Start chatting

Open a new conversation in ChatGPT and try a prompt that should trigger one of your tools. ChatGPT will discover your app’s tools automatically.Example:

Show me the support triage dashboard.

OAuth-Protected Apps

If your app has OAuth protection enabled, users connecting via ChatGPT will be prompted to sign in the first time they trigger a protected tool. The flow works like this:

User sends a message that triggers a protected tool.
ChatGPT shows a “Connect” or “Sign in” prompt.
User authenticates in a browser popup.
ChatGPT retries the tool call with the authenticated session.

No extra configuration is needed on the ChatGPT side. The sign-in prompt is handled automatically by the MCP connection.

Troubleshooting

Problem	Usually means	Fix
ChatGPT says “no tools found”	The MCP URL is wrong or the app has no published tools	Double-check the URL in app settings. Confirm your app has at least one tool.
Connection timeout	The endpoint is unreachable	Verify the slug is correct. Check that the app hasn’t been deleted or paused.
OAuth error or redirect loop	OAuth is not enabled	Check that OAuth Protection is toggled on in the Connect tab.
Tools appear but ChatGPT picks the wrong one	Tool descriptions overlap or are vague	Edit tool descriptions to be specific about when each tool should be used. See Tools.
