Connect American Express to Claude

Ask Claude about your real
American Express accounts — read-only.

Connect American Express to ClaudeRead-only. Free to start, no card needed.

Ledgerwire connects US banks, brokerages, and card issuers through the Finicity network. Outside the US, Connect will not find your bank.

Ask Claude about your real American Express card activity — read-only. Ledgerwire connects American Express 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.

Connect American Express in three steps

  1. 1 · Add
    In Claude, go to Settings → Connectors → Add custom connector. Enter the name Ledgerwire and the MCP URL https://ledgerwire.io/mcp, then authorize.
  2. 2 · Sign in
    Sign in to Ledgerwire (free, passwordless magic link), then connect American Express through its own secure sign-in window. Your credentials go to American Express, never to us.
  3. 3 · Ask
    Ask Claude anything about your American Express accounts. Answers are fetched on demand and discarded.

What you can ask

“…”
“What did I spend on my Amex last month?”
“…”
“What recurring subscriptions are on my Amex?”
“…”
“What's my current American Express balance?”

What Claude can see from American Express

Balances, transactions, spending by category, and recurring charges. Honest note: American Express does not report credit-card APR / rate detail through the aggregator network, so that specific field comes back as "not reported" (never a fake $0). Everything else works normally.

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 each answer states when your bank last reported. 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 American Express?
No — Claude has no native American Express integration. Ledgerwire is the bridge: a hosted, read-only MCP connector. You add https://ledgerwire.io/mcp to Claude once, connect American Express through the bank's own sign-in, and Claude can then read your accounts — nothing more.
Can Claude move money in my American Express 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 American Express data and nothing else.
Does Ledgerwire store my American Express 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 American Express login is never seen by Ledgerwire — you sign in through your bank's own secure window.
How do I connect American Express to Claude?
