Sandbox / simulated — not a real bank. Balances, accounts and transactions on this site are synthetic demo data. This is not a real bank or a real customer.

Give your AI tools read-only access to bank data.

Banker MCP is a Model Context Protocol server. Connect Claude, Cursor, VS Code, Codex or Gemini with one API key, and let your assistant look up accounts, balances and transactions at connected banks. It can read. It cannot move money.

No real bank is connected yet. Today every response comes from a synthetic sandbox bank and is labelled simulated: true. Banks join by signing an agreement with us; see Banks.

What you get

Four read-only tools

list_banks, list_accounts, get_balance, list_transactions. Every one is marked read-only so clients can approve them freely.

Honest data labels

Each result says which bank it came from and whether it is simulated, so an assistant cannot present sandbox data as real.

Metered and transparent

Every call is counted against your plan. Your dashboard shows usage by month and the last calls, tool by tool.

For banks

Banker MCP is designed so a bank keeps control: read-only scopes, customer consent, revocation, audit logs and a choice of hosting. See how banks connect.
