MCP server safety audit: completes a real initialize+tools/list handshake, then statically

MCP server safety audit: completes a real initialize+tools/list handshake, then statically scans every tool's name/description/schema for hidden unicode (tool-poisoning), prompt-injection-style phrasing, and tools that quietly combine multiple high-privilege capabilities (network+filesystem+exec+credential access). If a GitHub repo is supplied, folds in a real software-supply-chain signal too.
