Agentic banking & MCP

How the Model Context Protocol (MCP) fits next to open banking APIs—and why banks are adding MCP servers for AI assistants.

Institutions are starting to expose permissioned banking actions and data to AI clients via MCP, alongside traditional developer portals and PSD2-style APIs. Open Banking Tracker maps known MCP programs, ecosystem tools, and how consent and governance show up in agentic workflows.

Relay is listed here for open banking and API context. When we have confirmed MCP program details for this institution, they appear in this section automatically.

Relay Open Banking FAQ

Relay's direct API availability may be limited. However, you can often access Relay accounts through Open Banking aggregators like Plaid, Tink, or TrueLayer, which provide standardized connectivity to thousands of banks including Relay.

The easiest way to integrate with Relay is through an Open Banking aggregator. These services provide pre-built connections to Relay and handle authentication, data normalization, and compliance requirements on your behalf.

PSD2 compliance depends on Relay's operating jurisdiction. European banks must comply with PSD2, while banks in other regions follow their local Open Banking regulations. Check the compliance section above for specific certifications.

Through Open Banking APIs, you can typically access account balances, transaction history, account holder information, and in some cases initiate payments. The specific data available depends on Relay's API capabilities and the permissions granted by the account holder. All data access requires explicit customer consent.
