AI product Open source
Cata-centavo is a self-hosted MCP server that gives compatible AI agents read-only access to a user's Brazilian Open Finance bank, credit-card, and investment accounts through Pluggy. It runs locally over stdio, reads existing Pluggy connections identified by environment variables, and supports queries about transactions, spending categories, account balances, current card statements, unfamiliar charges, and investments. It has no hosted or multi-user service.
The package runs with Node.js 22.13 or newer and can be launched with npx. Its main commands include the MCP server itself, `init` for checking credentials and configured connections, and `doctor` for diagnosing connection status, consent, local cache, and learned categorization data. Provider transaction categories are copied into a persistent local `data.db`; the server also learns merchant-category associations from the user's transactions, and manually corrected or newly assigned categories are retained locally and applied retroactively.
