Mcp Safeguard

A security layer for your MCP setup that scans for common attack vectors before they reach your tools or prompts. It monitors for prompt injection attempts, catches accidentally exposed credentials in messages, detects server-side request forgery patterns, and flags suspicious tool configurations that might indicate poisoning attacks. Reach for this when you're exposing MCP servers to untrusted input or running in multi-tenant environments where one user's malicious prompt shouldn't compromise the system. Think of it as a firewall specifically tuned to LLM-specific threats rather than traditional web attacks. The scanning happens in the stdio transport layer, so it can inspect traffic without modifying your existing server implementations.
