AgentAuditKit is an open-source security scanner purpose-built for the emerging class of MCP-connected AI agent pipelines. Where traditional static analysis tools know nothing about tool descriptions, prompt injection surfaces, or trust boundary semantics, AgentAuditKit speaks the language of agentic systems. It ships with 77 detection rules across 13 specialized scanners that cover the full OWASP Agentic Top 10 and MCP Top 10 threat lists — all 20 out of 20. The scanner catches hardcoded secrets, shell injection in tool handlers, prompt injection embedded in MCP tool descriptions, rug pull patterns (tools that change behavior after trust is established), tainted data flows between agent layers, and trust boundary violations between orchestrators and sub-agents. It runs entirely offline, integrates as a GitHub Action, and maps every finding to EU AI Act, SOC 2, and HIPAA compliance frameworks. Install with pip and point it at your project. Internal benchmark data cited in the repo found vulnerabilities in 43% of public MCP servers tested. The timing is pointed: as MCP adoption accelerates from hobbyist to enterprise, the attack surface is growing faster than the security tooling. AgentAuditKit is the first dedicated scanner addressing this gap, and it's free.

AI-SPM (AI Security Posture Management) is an open-source infrastructure layer for securing LLM pipelines running in production. It targets three attack surfaces that traditional application security doesn't cover: prompt injection (including obfuscated and multi-step variants), tool abuse via unvalidated structured outputs, and data exfiltration through PII leakage in model responses. The architecture layers a gateway intercept layer over incoming prompts, runs context inspection before the LLM sees any input, enforces policies via Open Policy Agent (OPA) for declarative, auditable rules, then pipes all events through Apache Kafka and Apache Flink for real-time streaming analysis. This means security posture can be monitored and enforced at scale without blocking the inference path. The project is genuinely fresh — posted as a Show HN today. Early community feedback pointed to capability-based token models (similar to OS kernel permission rings) as a complementary approach to content-scanning, which the author acknowledged as a meaningful gap. The timing is right: as companies push AI agents from demos to production, the security tooling layer is largely underdeveloped. AI-SPM is one of the first OSS projects to tackle it at the infrastructure layer rather than with prompt-level guardrails alone.
Reviewer scorecard
“Every team shipping MCP servers needs this in their CI pipeline yesterday. The GitHub Action integration is clean, the OWASP mapping gives you a compliance paper trail, and it catches attack surfaces that no general-purpose linter would ever find. Runs offline so no source leaks.”
“OPA for policy enforcement means you can write Rego rules that your compliance team can audit — that's actually deployable in enterprise contexts. The Kafka/Flink pipeline is heavy infrastructure overhead for small teams, but for anyone running production agents at scale, this is addressing a real gap.”
“77 rules is a small ruleset for a security tool covering 20 OWASP categories — that's under 4 rules per category on average. The 43% vulnerability rate claim needs an independent audit; it could reflect a biased sample of low-quality public repos. I'd treat this as an early-warning complement to proper security review, not a replacement.”
“Content scanning for prompt injection is a cat-and-mouse game — adversarial prompts can be obfuscated faster than pattern libraries can be updated. The Kafka + Flink dependency stack is substantial for a project that just launched today with no production deployments documented. Wait for community hardening.”
“Security tooling always lags deployment by 2-3 years. The fact that a dedicated MCP security scanner exists this early in the MCP adoption curve is genuinely encouraging. This is the beginning of an agentic security ecosystem — expect a full stack of SAST, DAST, and runtime monitoring tools to emerge around it.”
“Agent security is the next frontier of the AI stack and it's almost entirely unsolved today. AI-SPM's framing — treat AI agents like network services with a dedicated security control plane — is the right mental model. This category will matter enormously as agents get production write access to real systems.”
“As someone building AI-powered creative tools that use MCP for file system access, knowing there's a scanner that specifically checks for prompt injection in tool descriptions is a relief. Creative tools handle sensitive IP — this kind of audit tooling gives studios the confidence to actually ship agentic features.”
“The GitHub repo is technically solid but documentation is still thin for anyone who isn't already comfortable with OPA and Kafka. Not a problem for security engineers, but the broader AI developer audience building agents will find it hard to evaluate what they're actually getting before investing in the stack.”
