How to connect Admillio.

Connect Claude and ChatGPT by signing in, no code needed. Cursor and VS Code with one button, Claude Code with one command.

Claude or ChatGPT: paste the link

In Claude or ChatGPT, go to Connectors, choose "Custom connector" and paste https://admillio.com/api/mcp. You sign in to Admillio, click Allow, and you're connected.

Cursor, VS Code or Claude Code: one click

Log in, go to Settings → AI connections and choose your app. Cursor and VS Code open automatically; for Claude Code you get a command to paste.

Set it up yourself

For other apps

Does your app use a key instead of signing in? Create one under Settings → AI connections and paste these settings.

Sign in and you're done

In Claude or ChatGPT you paste one link and sign in to Admillio. Cursor and VS Code open with one button from your settings. Want to run the server yourself? You can, via npm. Open source, Apache-2.0.

You ask, Admillio does it

Unprocessed receipts, dashboard totals, a draft invoice. You ask in the chat, and Admillio fetches or writes it in your books.

Your data, your choice

Each connection belongs to one user and only sees that organisation. When connecting, you choose what the app may access. You can revoke it at any time, with one click.

What MCP is, without having to know the protocol

MCP (Model Context Protocol) is the standard that lets AI assistants such as Claude and ChatGPT talk to other software. Admillio speaks that language. Ask in your chat how things stand, or have a draft invoice created, and Admillio does it in your books.

Connecting is just signing in: in Claude or ChatGPT you paste one link, sign in to Admillio and click Allow. For Cursor and VS Code there's a button in your settings. If you'd rather run the server yourself, you can via npm; open source, Apache-2.0.

What deliberately can't be done via MCP

No filing VAT returns with the Dutch Tax Administration, no making payments, no changing your subscription, no access to anyone else's data. You don't delete sent invoices: you use a credit note for that. That keeps the audit trail intact.

MCP is an extra way into the same bookkeeping, not a second version of the truth. Whatever you create in the chat shows up in your dashboard.
