patronus-security

Patronus is a security scanner for AI agents and MCP workflows. It helps detect prompt injection, malicious instructions, and sensitive-data exposure before untrusted content reaches an agent. Scan text, documents, public URLs, or complete MCP servers through a remote MCP endpoint. A limited text scan is available without authentication; advanced scans use OAuth 2.1 with PKCE. Patronus returns structured findings that agents can evaluate or use as a security gate before processing external content.
