CAUTION

Publisher claims: "元信MCP（yotta-verify-mcp）—— 把元信（yotta-verify）装前安全扫描暴露为 stdio MCP server，提供 scan_skill（目录/包 → verdict+发现）、generate_badge（audited 徽章）、gate_check（CI 闸门）、get_report（JSON/Markdown 双视角综合报告）四个 MCP 工具。触发：给 MCP 客户端配置元信MCP、把装前信任扫描接入智能体/工作流、调用上列 MCP 工具做扫描；或用户说 MCP元信/元信MCP/trust-mcp/scan-mcp 等。边界：本地离线静态扫描，不上传被测内容、不执行被测代码、不联网；结论需人工确认。MCP 配置与全局/永久记忆写入均为可选，必须先获得用户明确同意；未获同意前不写任何文件，可直接降级 CLI。" Observed in sandbox: no network, touches nothing outside the project, writes no memory.
