Open Financial Data Protocol

Open Financial Data Protocol

A consumer-owned, federated, open standard for personal financial data.

The Problem

Fragmented

Consumer financial data is scattered across hundreds of institutions with incompatible formats and no standard way to access it.

Intermediated

Aggregators like Plaid and MX charge institutions for access to data consumers generated, creating misaligned incentives.

Opaque

No standard provenance model means consumers and AI agents can't tell where data came from or how much to trust it.

What OFDP Is

OFDP is a data layer — not a payment system. It defines how financial data is structured, stored, shared, and verified across institutions, applications, and AI systems. It is designed to complement FDX and Section 1033 infrastructure by adding a consumer sovereignty layer.

Consumer Owned

Your instance is the authoritative source for your financial identity. Institutions are data sources, not data owners.

AI Native

Structured, normalized data designed to be consumed by AI agents without transformation.

Self Hostable

Runs on modest hardware. No cloud dependency required.

Built to Coexist

FDX

OFDP consumes FDX-compliant APIs as a data source

ISO 20022

Transaction fields map directly to OFDP schema

OAuth 2.0

Foundation for all ConnectionRequest authorization

MCP

OFDP instances expose MCP servers for AI agent access

Section 1033

OFDP is the consumer layer above institutional infrastructure
