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.

QSAG-Core is a Python security scanner specifically designed for the OWASP Top 10 for Agentic Applications 2026 threat model. It provides three core detection capabilities: MCP tool poisoning (26 malicious patterns across 7 categories), prompt injection (28+ attack patterns including goal hijacking, jailbreak attempts, and memory poisoning), and ghost agent detection for unauthorized API key usage. It runs as pure pattern matching — no ML, no cloud dependency — and can be integrated as a pre-execution guard in any Python-based agent pipeline. Released April 10, 2026 by the Neoxyber team, QSAG-Core fills a real operational gap as MCP-based agent deployments proliferate. While Microsoft's Agent Governance Toolkit addresses similar territory, it's heavyweight and enterprise-focused. QSAG-Core is a pip install and a few lines of code — the security-focused indie alternative that fits into a CI/CD pipeline or an existing agent framework without an enterprise contract. The threat model it addresses is timely. As MCP becomes the de facto standard for tool-calling in AI agents, malicious MCP servers and prompt injection via tool outputs are becoming documented attack vectors. Having a lightweight, open-source scanner that specifically targets these patterns is exactly what the community has been building toward. MIT licensed, 24 commits in its first day.
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.”
“I've been manually reviewing MCP tool schemas before deploying them — QSAG-Core automates that. 26 MCP poisoning patterns and 28 prompt injection patterns in a single pip install is a no-brainer to add to any agent pipeline's security layer.”
“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.”
“Pattern matching is a starting point, not a solution. Sophisticated prompt injection and MCP poisoning attacks are designed specifically to evade signature-based detection. QSAG-Core will catch known-bad patterns, but a determined attacker will trivially bypass it. This is necessary but not sufficient security.”
“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.”
“Every major software ecosystem eventually got linters, scanners, and static analysis tools. QSAG-Core is the beginning of that toolchain for AI agents. The OWASP Agentic AI threat model it implements will become the industry baseline. Early adopters of agent-specific security tooling will be ahead of the curve when regulations arrive.”
“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.”
“Non-technical teams building AI-powered tools with MCP have no idea what tool poisoning even is. QSAG-Core gives developers a way to add a meaningful security layer that they can explain to stakeholders without a security engineering background.”
