Security scanner for MCP servers with vulnerability detection and prompt injection analysis.
If you already use MCP, the mcp mcp server is the piece that lets your assistant work with it directly. Security scanner for MCP servers with vulnerability detection and prompt injection analysis.
Done! Now ask Claude: "Is @modelcontextprotocol/server-github safe to install?"
The server ships on npm as @smithery/cli, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Configuration is passed through the environment: YOUR_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. It is maintained by mcp-fortress; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against MCP's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
