Connect ChatGPT

What you need

A ChatGPT account that can add a custom MCP server on ChatGPT web. Workspace permissions and security restrictions apply to adding custom MCP servers.

For paid setup you also need a Tyton account and plan. If you don’t have them yet, Tyton walks you through both when you sign in.

Add Tyton

These steps follow OpenAI’s guide to adding a custom MCP server. Labels can change, so follow the closest match on your screen.

1. Go to Plugins in ChatGPT, select the plus button, then Add custom MCP server.
2. Name it Tyton. Under Connection, enter https://mcp.usetyton.com/mcp as the server URL.
3. For authentication, choose OAuth.
4. Read the warning, select I understand and want to continue, then select Create as a plugin.
5. Install the Tyton plugin. In a new chat, type @ in the message box and pick Tyton.

Sign in and pick your website

1. When ChatGPT asks you to connect Tyton, continue. Tyton’s sign-in page opens and names the app ChatGPT (chatgpt.com).
2. Sign in to Tyton, or create an account and choose a plan.
3. Under Website it can use, pick your website, or choose Add a website if your plan has a free site slot. Select Allow access.
4. You’ll return to ChatGPT. Ask it to continue setup.

Run the free audit only

To use only the free audit, add a second custom MCP server with https://mcp.usetyton.com/audit and choose No authentication. That server never asks you to sign in and can’t start paid setup.

Success check

ChatGPT can read setup progress for the website you picked and tells you its name or address. Seeing Tyton’s tools in ChatGPT shows only that the URL works.

If you get stuck

• The sign-in page says the request has ended: the request timed out or was already used. Go back to ChatGPT and start sign-in again from there.
• Your site slots are all in use: review your plan in Tyton, or remove a website you no longer need, then connect again from ChatGPT.
• ChatGPT connected to the wrong website: select Disconnect for it on the Integrations page in Tyton, then connect again and pick the right one.
• The sign-in page says “We couldn’t verify this app”: go back to ChatGPT and connect Tyton again. If you see it again, contact Tyton support.
• You can’t find Add custom MCP server: your workspace may restrict custom MCP servers. Ask your workspace admin.

Don’t paste a Tyton server key into a chat message or the server URL. Signing in gives ChatGPT access to the website you picked. Read connection permissions before you start setup.
