MCP server for local transaction signing on EVM, UTXO, Tron, and XRP — no API calls needed
Runs locally over stdio
This server isn't hosted — your MCP client launches it from a package registry. Use one of the commands below, or drop the config into your client (e.g. Claude Desktop).
Run
npx -y @cryptoapis-io/mcp-signer
