Before you start
- A Mingo account, Free or Pro. No account yet? Get the app.
- An account with the AI assistant you want to use.
- A minute: you sign in with Mingo once, and the assistant remembers the connection.
Read only. The connector can read your Mingo account but never changes, deletes or sends anything. The assistant reads only what it needs to answer your question. Details: AI connector privacy.
Pick your assistant:
Claude
Works in Claude on the web, the desktop app and the iOS and Android apps. Connect once and Mingo is there on every device signed in to your Claude account.
- In Claude, open Customize → Connectors (claude.ai/customize/connectors).
- Find Mingo and choose Connect.
Not listed yet? Choose Add custom connector, name it
Mingo, enterhttps://mcp.mingo.cards/mcpand leave the advanced settings empty. - The Mingo sign-in page opens. Sign in with your Mingo account.
- Check what Claude will be able to read and choose Allow.
- In a chat, make sure Mingo is on under + → Connectors, then ask away.
On a Team or Enterprise plan, an owner may need to add Mingo for the organization first. Each member then connects their own Mingo account.
ChatGPT
- In ChatGPT, open the apps directory and search for Mingo.
- Choose Connect. The Mingo sign-in page opens.
- Sign in with your Mingo account, check what ChatGPT will be able to read and choose Allow.
- In a chat, pick Mingo from the + menu or mention Mingo in your question.
Mingo not in the directory yet? Add it in Developer mode (Plus, Pro, Business, Enterprise and Edu plans): Settings → Apps → Advanced settings, turn on Developer mode, then create an app named Mingo with the URL https://mcp.mingo.cards/mcp and authentication OAuth, client ID and secret empty. ChatGPT cannot send custom headers, so use OAuth, not a personal key.
Codex
Install the Mingo plugin from the Codex plugin directory (type /plugins in codex), or add the server yourself in a terminal:
codex mcp add mingo --url https://mcp.mingo.cards/mcp
codex mcp login mingo # opens the Mingo sign-in page
On a machine without a browser, add --no-browser to the login command and open the link it prints on another device.
In the ChatGPT desktop app or the IDE extension: Settings → MCP servers → Add server, type Streamable HTTP, URL https://mcp.mingo.cards/mcp, then Authenticate.
Other MCP apps
Any app that supports remote MCP servers can use Mingo.
| Setting | Value |
|---|---|
| Server URL | https://mcp.mingo.cards/mcp |
| Transport | Streamable HTTP |
| Sign-in | OAuth (the app opens the Mingo sign-in page), or a personal API key |
Sign in with OAuth
If the app supports OAuth for MCP servers, add the URL and leave the credentials empty. The app finds the Mingo sign-in page by itself. For example, Claude Code:
claude mcp add --transport http mingo https://mcp.mingo.cards/mcp
# then run /mcp in Claude Code and choose Authenticate
Or use a personal API key
For apps without OAuth: in the Mingo app open Settings → AI assistants → New key, or on the web open app.mingo.cards/dashboard/mcp → Create personal key. Name it, pick when it expires (1 hour to never; 3 months by default) and copy it: it starts with mingo_pk_ and is shown only once. Send it as a header. For example, Cursor (~/.cursor/mcp.json):
{
"mcpServers": {
"mingo": {
"url": "https://mcp.mingo.cards/mcp",
"headers": { "Authorization": "Bearer mingo_pk_…" }
}
}
}
Treat a key like a password: anyone who has it can read your Mingo account. You can make up to 10 keys and revoke any of them in the app or at app.mingo.cards/dashboard/mcp. In Codex, keep the key in an environment variable: codex mcp add mingo --url https://mcp.mingo.cards/mcp --bearer-token-env-var MINGO_API_KEY.

Disconnect
- In Mingo: open app.mingo.cards/dashboard/mcp (menu MCP) and choose Disconnect next to the assistant. Access stops within one minute.
- In Claude: Customize → Connectors, select Mingo, then disconnect or remove it.
- In ChatGPT: Settings → Apps, select Mingo, then disconnect.
- In Codex: run
codex mcp logout mingo, or remove Mingo under Settings → MCP servers. - A personal key: revoke it in the Mingo app under Settings → AI assistants, or at app.mingo.cards/dashboard/mcp.
Disconnecting never deletes anything in your Mingo account.
Troubleshooting
The assistant asks me to sign in again
Connect again. A connection unused for 30 days has to sign in again. Connecting again adds a new connection; nothing else is disconnected.
“Too many AI connections”
An account can hold up to 20 connections. Disconnect the ones you no longer use at app.mingo.cards/dashboard/mcp, then connect again.
The sign-in page does not open
Allow pop-ups for the assistant's website, or try again in a normal (not private) browser window.
The assistant does not use Mingo
Check that Mingo is turned on for the chat (in Claude under + → Connectors, in ChatGPT from the + menu), or mention Mingo in your question.
A contact is missing
The assistant sees only contacts saved in your Mingo account. Check in the app that the scan or save finished.
Does connecting one assistant disconnect another?
No. Every sign-in is its own connection, so Claude, ChatGPT and Codex can all be connected at the same time.
