Promptrejectormcp

A security layer that screens user input before it hits your AI agent. Exposes check_prompt, scan_skill, and check_url tools via MCP, plus a parallel REST API for web integrations. Combines Gemini semantic analysis with regex pattern matching to catch prompt injections, jailbreaks, XSS, SQLi, and shell injection attempts. Returns structured severity scores and category tags so you can route critical threats differently than low-risk queries. The skill scanner is built specifically for Claude Code SKILL.md files. Ships with a dynamic pattern library, CVE feed integration, and optional canary token deployment. Runs as stdio transport, requires a Gemini API key, and works alongside output filtering and sandboxing rather than replacing them.
