RealOpen for Claude

RealOpen runs as a remote MCP connector in Claude today. Connect in under a minute — no RealOpen account required to get started — and generate verified proof-of-funds letters, check wallet balances, and add new wallets directly from your Claude conversation.

What you can do

  • Check your connected wallets and verified balance
  • Generate proof-of-funds letters for specific offer amounts
  • Add and verify new wallets
  • Learn how the buyer flow works at closing

Setup

  1. In Claude, go to Settings → Connectors → Add custom connector.
  2. Paste the connector URL: https://mcp.realopen.app/claude/mcp.
  3. Sign in with your existing RealOpen account, or create a new one — both options are available in the OAuth flow.
  4. Try it: ask Claude "show me my RealOpen wallet summary".

One account, everywhere

The RealOpen account you connect in Claude is the same account you can manage on realopen.com or through any other connector. Wallets, verifications, and Proof-of-Funds letters sync across all of them.

Sign-in is OAuth — Claude never sees your RealOpen password, and RealOpen never sees your wallet's private keys or seed phrase. Wallet ownership is proven by you signing a message in your own wallet, or by sending a small on-chain test transfer. The connector accesses only your RealOpen account data (wallets, verifications, POF history) and the on-chain balances of the public addresses you've added. See the privacy policy for full details.

Tools reference

These are the tools the RealOpen MCP server exposes. Claude invokes them automatically when your conversation calls for them — you don't need to call them by name. The list below documents every tool, what it does, and what it returns, so you can understand the full surface area before connecting.

Troubleshooting

“Wallet not verified” after signing

Refresh your wallet summary. If still unverified, the signature may have been rejected — try the test-transfer method instead.

POF generation fails

Most common causes: the requested amount exceeds your verified ceiling, or your identity verification (KYC) isn't complete. Check your account status on realopen.com.

OAuth login fails or loops

Clear cookies for realopen.com and retry. If the issue persists, contact support.
