sign_message

MCP tool from Bambu MCP by schwarztim

Sign message with X.509 certificate for firmware auth bypass

How to use it

Project documentation lists sign_message for the Bambu MCP 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.
