About Open Finance MCP
Open Finance MCP is a Model Context Protocol (MCP) server that connects a user's bank data to MCP-compatible AI assistants via Brazil's Open Finance framework. It enables natural-language queries over bank statements without requiring a separate account, using regulated consent and live data calls.
Review
Open Finance MCP focuses on making personal banking data accessible inside AI chat clients by routing consented Open Finance data into an MCP context. The implementation emphasizes user control: authentication happens through the bank using a tax ID (CPF) and consent can be revoked at any time.
Key Features
- Direct MCP integration so AI clients can query bank statements via a provided MCP server URL.
- Authentication and consent handled through Brazil's Open Finance flow (CPF + bank) with no separate account creation.
- Real-time queries without persistent storage of financial data, with access revocable at the bank level.
- Fast setup (reported as around two minutes) and an MVP scope that currently supports one account's bank statements.
- Rate-limited access intended for lightweight, personal queries (current limit ~5 queries/day).
Pricing and Value
The service is listed as free at launch. Its main value proposition is letting users ask natural-language questions of their own bank data inside the AI tools they already use, without creating new accounts or uploading statements. Because the flow uses the regulated Open Finance protocol, it leans on existing consent controls and legal protections; however, the MVP constraints (single-account scope and a low daily query limit) mean it is best suited to exploratory use and low-frequency personal queries rather than heavy-duty accounting or multi-account aggregation.
Pros
- Strong consent model: authentication and revocation happen through the bank's regulated Open Finance flow.
- No account creation or credential sharing with the MCP server; access is token-based and scoped.
- Quick to set up and integrates into existing AI clients via MCP.
- Live, on-demand queries without storing users' financial records on the MCP server.
Cons
- MVP limitations: currently supports only one account / one bank per consent and a small daily query allowance (~5/day).
- Coverage is limited to banks participating in Brazil's Open Finance; multi-bank workflows require additional work or future feature updates.
- Not yet suited for professionals who need high-volume queries, detailed multi-account reconciliation, or advanced accounting features.
Overall, Open Finance MCP is a practical option for individuals in Brazil who want occasional, natural-language access to their own bank statements inside AI assistants or for developers testing MCP integrations. It fits best for personal budgeting checks, quick spending summaries, and prototype builds; users or teams needing broader multi-account support and higher query volumes should watch for upcoming feature expansions.
