I built Mithra: a security scanner for LLM-integrated APIs (detects prompt injection, DAN..)

Hey folks,

I just launched Mithra, a security scanner built specifically for REST APIs that integrate large language models like GPT, Claude, open-source LLMs , anyone!

LLM-backed endpoints introduce a new set of risks—prompt injection, context leakage, over-permissive outputs, even logic abuse through natural language. Traditional API scanners don't catch these.

Mithra scans for both OWASP API Top 10 and LLM-specific threats, directly with 3 clicks (no agents, no container dependencies). It’s designed for devs shipping LLM-powered features like search, summarization, chatbots, or completions.

What it does:
– Detects prompt injection, do anything now, Insecure output handling, sensitive information disclosure etc..
– Flags data/context leakage and logic gaps

Would love feedback from folks building or securing LLM interfaces. Happy to answer questions!
