Connect Comerica to Claude

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

Ask Claude about your real Comerica accounts — balances, transactions, and spending, read-only. Ledgerwire connects Comerica 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.

Get started free

Connect Comerica 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 Comerica through its own secure sign-in window. Your credentials go to Comerica, never to us.
  3. 3 · Ask
    Ask Claude anything about your Comerica accounts. Answers are fetched on demand and discarded.

What you can ask

“…”
“What did I spend from my Comerica account last month?”
“…”
“What's my Comerica checking balance?”
“…”
“What recurring charges are on my Comerica card?”

What Claude can see from Comerica

Balances, transactions, spending by category, and recurring charges. You sign in through Comerica’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 Comerica?
No — Claude has no native Comerica integration. Ledgerwire is the bridge: a hosted, read-only MCP connector. You add https://ledgerwire.io/mcp to Claude once, connect Comerica through the bank's own sign-in, and Claude can then read your accounts — nothing more.
Can Claude move money in my Comerica 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 Comerica data and nothing else.
Does Ledgerwire store my Comerica 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 Comerica login is never seen by Ledgerwire — you sign in through your bank's own secure window.
How do I connect Comerica to Claude?
In Claude, add the Ledgerwire connector (Settings → Connectors → add https://ledgerwire.io/mcp), sign in to Ledgerwire (free, passwordless), connect Comerica through its secure sign-in, then ask Claude about your accounts.
What can Claude see from Comerica?
Balances, transactions, spending by category, and recurring charges. You sign in through Comerica’s secure flow; Ledgerwire never sees your credentials.
