Connect Vanguard to Claude

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

Ask Claude about your real Vanguard investment accounts and holdings — read-only. Ledgerwire connects Vanguard 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 Vanguard 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 Vanguard through its own secure sign-in window. Your credentials go to Vanguard, never to us.

What you can ask

“…”
“What are my Vanguard holdings worth right now?”
“…”
“What funds and positions do I hold at Vanguard?”
“…”
“How is my Vanguard portfolio allocated?”

What Claude can see from Vanguard

Investment accounts, holdings/positions, and balances. Holdings come from the Finicity network, so a position with no reported value shows as "not reported" rather than $0 — your portfolio sums stay honest. You sign in through Vanguard’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 Vanguard?
No — Claude has no native Vanguard integration. Ledgerwire is the bridge: a hosted, read-only MCP connector. You add https://ledgerwire.io/mcp to Claude once, connect Vanguard through the bank's own sign-in, and Claude can then read your accounts — nothing more.
Can Claude move money or place trades in my Vanguard account?
No. Ledgerwire is read-only by architecture — there is no transfer, payment, trading, or account-change tool anywhere in the product. Claude can read your Vanguard balances, positions, and history, and nothing else.
Does Ledgerwire store my Vanguard 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 Vanguard login is never seen by Ledgerwire — you sign in through your bank's own secure window.
How do I connect Vanguard to Claude?
In Claude, add the Ledgerwire connector (Settings → Connectors → add https://ledgerwire.io/mcp), sign in to Ledgerwire (free, passwordless), connect Vanguard through its secure sign-in, then ask Claude about your accounts.
What can Claude see from Vanguard?
Investment accounts, holdings/positions, and balances. Holdings come from the Finicity network, so a position with no reported value shows as "not reported" rather than $0 — your portfolio sums stay honest. You sign in through Vanguard’s secure flow; Ledgerwire never sees your credentials.
