Connect KeyBank to Claude

Ask Claude about your real
KeyBank accounts — read-only.

Ask Claude about your real KeyBank accounts — balances, transactions, and spending, read-only. Ledgerwire connects KeyBank to Claude (or Cursor, Claude Desktop, any MCP client) through your bank's own secure sign-in. It can never move money, and it keeps no copy of your data.

What Claude can see from KeyBank

Balances, transactions, spending by category, and recurring charges. You sign in through KeyBank’s secure flow; Ledgerwire never sees your credentials.

Coverage depends on your bank: some institutions report categories, APR, or holdings and some don't. A missing field always comes back as “not reported”, never a fake $0, and bank data lags posting by a few days. See the FAQ for the full coverage story.

Read-only, by architecture

Can't move money

There is no transfer, payment, or account-change tool — the capability doesn't exist in the product.

Scoped, revocable access

claude.ai authorizes with OAuth 2.1; other clients use a scoped token — both read-only and revocable in one click. No long-lived shared key.

Nothing stored

Every read is fetched on demand and discarded; your transactions and balances are never written to our database. More on the Trust Center and security page.

Questions

Does Claude connect directly to KeyBank?

No — Claude has no native KeyBank integration. Ledgerwire is the bridge: a hosted, read-only MCP connector. You add https://ledgerwire.io/mcp to Claude once, connect KeyBank through the bank's own sign-in, and Claude can then read your accounts — nothing more.

Can Claude move money in my KeyBank account?

No. Ledgerwire is read-only by architecture — there is no transfer, payment, or account-change tool anywhere in the product. Claude can read your KeyBank data and nothing else.

Does Ledgerwire store my KeyBank transactions?

No. Every answer is fetched on demand when you ask and then discarded. Your transactions and balances are never written to Ledgerwire's database, and your KeyBank login is never seen by Ledgerwire — you sign in through your bank's own secure window.

How do I connect KeyBank to Claude?

In Claude, add the Ledgerwire connector (Settings → Connectors → add https://ledgerwire.io/mcp), sign in to Ledgerwire (free, passwordless), connect KeyBank through its secure sign-in, then ask Claude about your accounts.
