Every Omie account of your firm, in one connector for your AI assistant

MCP Omie is an MCP connector for accounting firms and business groups in Brazil that work with several Omie ERP accounts. It lets an AI assistant — Claude, for example — query and operate the Omie account of each company a person has access to, and several of them at once.

Invitation-only pilot. The service is being tested with a small group of customers. To take part, write to [email protected].

What it does

Answers questions across companies at once ("what is overdue across all my clients?"), per company and in total.
Covers receivables and payables, bank statements and reconciliation, sales orders, invoices, stock and registers.
Never runs a payment, billing or cancellation without showing a preview and getting the person's explicit approval.

How access works

Each customer has an isolated space; no one sees another customer's companies.
The customer registers the Omie API key of each company; it is stored encrypted and never shown again.
People join by invitation, with read or write access to all or some companies.
Sign-in happens at https://idp.damasiormoura.org; the connector is https://mcp-omie.damasiormoura.org/mcp.
Works with AI assistants that accept remote MCP connectors with OAuth — Claude, ChatGPT, VS Code/GitHub Copilot, Cursor, Claude Code, Gemini CLI and others; each firm chooses which to enable. See how to connect.

Your data

ERP data stays in Omie: the service fetches it when you ask and keeps no copy. We only keep your account, the encrypted API keys and an audit trail of who did what. See the privacy policy and the terms of use.

Sign in with Google

If you sign in with your Google account, we receive only your name, your email address and the fact that it is verified, to know who you are and match your invitation. We do not access your email, files or any other Google account data, and we use this information for no other purpose.
