Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Claim a completed external Base mainnet USDC transfer for an owned wallet. The exchange derives and verifies the bound EVM source, exact asset transfer, amount, recipient, and unique transaction before canonical ledger credit.
This tool isn't marked read-only, so it may change something on the server or in an account you connected.
