Agent Prompt Injection Firewall MCP
WAF for AI agents — block prompt injection before it reaches the LLM

Why this exists
The EU AI Act (Aug 2026), DORA (live), ISO 42001, and OWASP LLM01 Top-10 all demand runtime controls for agent systems — not just deployment-time audits. This MCP is that runtime control layer, emitting cryptographically signed evidence your auditor accepts.
