sign_message

MCP tool from Evm MCP Server by mcpdotdirect

Sign arbitrary messages for authentication and verification (SIWE, off-chain signatures)

How to use it

Project documentation lists sign_message for the Evm MCP Server MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
