Connect me to Munch, my nutrition tracker.

Add Munch as a custom connector / MCP server in this app:
• Name: Munch
• Server URL: https://munch.business/mcp
• Sign-in: OAuth — it opens a Munch page in my browser.

Start the connection and walk me through anything I need to tap, one step at
a time. Sign-in is by email link: I enter my email on the Munch page, open
the link they send, and approve the connection. If I've never used Munch,
that same link creates my account — there's no separate sign-up and no
password.

One thing to know first: MCP access is part of Munch Premium ($3/month).
The Munch website and app are free and fully featured; connecting through
an AI app is the Premium part. If my account does not have Premium yet,
the approval page will say so — tell me plainly, and point me to
munch.business, where Premium is managed on the website.

When the connection is live, confirm it worked — then ask me if I want to
log my first meal or set a nutrition goal.

No password, ever. Sign-in is a single-use email link — and if you are new, that same link creates your account. Connecting uses MCP access, which is part of Munch Premium ($3/month); the website and app themselves are free and fully featured.

Claude ChatGPT Muse Any MCP app

Claude — exact steps

Open Claude and go to Customize → Connectors (in some versions this lives under Settings → Connectors).
Choose +, then Add custom connector.
Enter Name: Munch and the server URL: https://munch.business/mcp, then choose Continue. Leave the Advanced OAuth fields empty — Munch registers itself automatically.
Review the sign-in settings Claude detected, then choose Add.
Choose Connect — your browser opens a Munch page. Enter your email, open the sign-in link Munch sends, and approve the connection.
Return to Claude, turn Munch on in your chat, and ask: “Log my lunch.”

Connector name: Munch
Server URL: https://munch.business/mcp
Authentication: OAuth — sign in on the Munch page

Custom connectors are available on Free, Pro, Max, Team, and Enterprise plans; free accounts can keep one custom connector. On Team and Enterprise, an owner adds connectors for the organization.

ChatGPT — exact steps

On ChatGPT on the web, open Settings → Apps & Connectors.
Scroll to Advanced settings and turn on Developer mode. (Your AI cannot flip this switch for you — this one is yours.)
Back in Apps & Connectors, choose Create.
Enter Name: Munch, the MCP server URL: https://munch.business/mcp, and set Authentication to OAuth. Confirm the acknowledgement and choose Create.
Your browser opens a Munch page: enter your email, open the link sent to you, and approve the connection.
Return to ChatGPT, enable Munch in your chat from the + menu, and start logging.

Connector name: Munch
Server URL: https://munch.business/mcp
Authentication: OAuth — sign in on the Munch page

Honest note: custom connectors in ChatGPT need Developer mode, which is a paid-plan feature (Plus, Pro, Business, Enterprise, and Edu) on the web — free accounts do not have it, and a workspace admin may need to allow it first. If you do not see the option, your plan may not have it yet.

Muse — exact steps

In your terminal, add Munch as a remote MCP server:
claude mcp add --transport http Munch https://munch.business/mcp
Start Muse and run /mcp, then choose Munch and Authenticate.
Your browser opens a Munch page: enter your email, open the sign-in link, and approve the requested permissions.
Return to Muse: /mcp shows Munch connected, and its 95 tools are available in your session.

Connector name: Munch
Server URL: https://munch.business/mcp
Authentication: OAuth — sign in on the Munch page

Using the Muse app instead? Add Munch under Customize → Connectors with the same name and URL, exactly as in the Claude tab. Muse connects to the same endpoint and the same account as every other client — connect once per app, use one shared record.

Any MCP app — exact steps

Open your app's settings and look for Custom connector, MCP server, or Remote server.
Add a server with Name: Munch.
Paste the Server URL: https://munch.business/mcp.
Choose OAuth for authentication and start the connection.
In the Munch page that opens, enter your email, open the link sent to you, and approve.
Return to your app and confirm Munch shows as connected.

Connector name: Munch
Server URL: https://munch.business/mcp
Authentication: OAuth — sign in on the Munch page

Munch is a remote MCP service using OAuth 2.1 + PKCE + DCR, so any standards-based MCP client can connect the same way.

How sign-in works — four steps

Paste

Paste the block above into your AI app. It tells your assistant exactly what to add and how to guide you.

Connect

Your assistant starts the connection, or walks you tap-by-tap through adding the custom connector.

Email link

Enter your email on the Munch page and open the single-use link sent to you. New to Munch? That same link creates your account — no separate sign-up, no password.

Approve → connected

Review the permissions on the approval page and approve. You return to your AI, connected — it will confirm and offer to log your first meal or set a goal.

Troubleshooting & permissions

What am I granting?

The approval page lists the exact permissions requested. Approving lets that app call the matching Munch tools for your account only. Munch does not receive your unrelated conversations in that app.

The email link did not arrive

Check spam and filtered folders, confirm the address is typed correctly, then request a fresh link. Links are single-use and expire; a delayed older link may stop working once a newer one is requested. A confirmation tap on the Munch page stops automated email scanners from consuming your link first.

“This request expired”

Authorization requests are intentionally short-lived. Do not reuse the old browser tab — return to your AI app and choose Connect again to start a fresh request. Closing the browser, switching devices mid-flow, reusing a consumed link, or blocking required cookies can also interrupt a connection.

How to revoke access

Open Munch Settings → Connections and revoke the connection you no longer want. Revoking stops that token family immediately; it does not delete your Munch account or your nutrition records.

Still stuck? Email support@munch.business and say which app you are connecting from.

One account, every conversation

Munch is persistent nutrition for your AI: 95 MCP tools and sign-in by email link. The website and app are free and fully featured; MCP access is part of Premium ($3/month), which also makes the app ad-free and will include the in-app AI chat agent when it launches.
