Most "bank account MCP" projects on GitHub are thin wrappers around Plaid or Teller. This directory tracks the banks and financial platforms that have shipped a first-party MCP server themselves: hosted on the bank's own infrastructure, with the bank's own auth, exposing the bank's own data and actions. We track launch date, access level (read-only vs read-write), supported AI clients, and what each server can actually do.

API aggregators with MCP servers
Open-banking and financial-data aggregators that ship their own MCP servers. These are the "wrapper" tier — agents talk to the aggregator, which talks to the underlying banks. Different trust model than the first-party bank servers above, but useful for broad coverage where banks don't yet ship MCP themselves.
What counts as a "real" bank MCP server?
The market has three very different categories of MCP server that touch banking. They're often lumped together but the trust model is completely different.
| Type | Who controls auth? | Examples |
|---|---|---|
| First-party bank MCP | The bank itself | Mercury, Meow, Griffin, Grasshopper |
| Aggregator MCP wrapper | Plaid / Teller / SimpleFin | Most GitHub "bank account MCP" repos |
| Browser-session MCP | The user's logged-in tab | OpenTabs and similar tools |
This directory only lists category one. Aggregator wrappers and browser-session tools are interesting and useful — they're just a different trust contract.

Our pillar page on agentic banking and MCP covers what the protocol is, why banks are adopting it, the consent and audit model, agentic banking use cases, and the broader ecosystem of MCP tools for finance.
