What is Grasshopper Bank's MCP server ?

It's a secure middleware layer that feeds your bank data to external AI tools like Claude, with strict read-only access and bank-controlled permissions — no more manual exports.

How does MCP keep my data safe?

By authenticating users, limiting to permitted data, assuming AIs are untrusted, and blocking any write actions like transactions.

Will banks like Grasshopper let AI make payments soon?

Not yet — MCP is read-only now, but expect pressure for agentic features if security holds.
