LLMSecure

LLMSecure is a free security scanner designed to identify prompt injection attacks and manipulation techniques targeting AI systems. It analyses prompts, URLs, files, and MCP (Model Context Protocol) servers to detect vulnerabilities before they reach your language models. The tool requires no sign-up, making it quick to test suspicious inputs or review your own prompts for security gaps. It's particularly useful for developers, security teams, and anyone deploying AI agents in production environments where injection attacks pose a real risk. By catching these threats early, you can prevent unauthorised prompt manipulation, data leakage, or unexpected AI behaviour.
