sign_action

MCP tool from Matrixscroll by SSX360

Signs provenance for CI, infrastructure changes, migrations, API calls, or other actions

How to use it

Project documentation lists sign_action for the Matrixscroll 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.
