prompt-injection MCP servers & tools

Runtime governance for MCP tool calls. Blocks prompt injection and capability abuse before tool results reach your agent.

Security intelligence for AI agents: password breach checks (900M+ HIBP hashes), email/domain/IP/URL reputation, prompt injection detection (200+ patterns), and skill supply chain scanning. Pay-per-request via x402 USDC micropayments or free demo mode, no API key needed.

Beelzebub is a honeypot framework that lets you build honeypot tools using MCP. Its purpose is to detect prompt injection or malicious agent behavior. The underlying idea is to provide the agent with tools it would never use in its normal work.
