MCP

MCP – your AI assistant with read access to your books

MCP (Model Context Protocol) is the standard AI assistants use to pull data from other systems. Numina's MCP server gives Claude, ChatGPT, Codex, Cursor and any other MCP client read access to your bookkeeping, so you can ask about expenses, revenue, chart of accounts, transactions and invoices in plain language — without exporting a single file.

With MCP you get:

• Answers to questions about your books, asked in plain language
• Analysis of expenses and revenue over time, with no export to a spreadsheet
• Lookups in your chart of accounts, transactions and invoices straight from the assistant
• Read-only access — the assistant can neither create nor change anything, and you can revoke access at any time

Here's why it's smart

Your bookkeeping runs itself in Numina, and MCP lets you ask about it where you already work. “What did I spend on software last quarter?” or “Which invoices are overdue?” gets answered from your own up-to-date numbers — not from a guess.

How do I get started?

You connect your AI assistant yourself inside Numina, and it takes a couple of minutes. The app has a “Connect an AI assistant” guide that walks you through it: copy Numina's server address into Claude, ChatGPT, Codex or Cursor, sign in and approve that the assistant may read along. Then ask away — and you can revoke access again in one click.
