The Agent Governance Toolkit is Microsoft's open-source (MIT) answer to one of the biggest gaps in the agentic AI ecosystem: runtime governance. As AI agents gain the ability to execute code, make API calls, and take consequential real-world actions, enforcing policies at runtime — without human checkpoints — has become critical. This toolkit addresses it at the framework level. The core is a stateless policy engine that intercepts every agent action before execution, running at sub-millisecond latency. It maps directly to all 10 risks in OWASP's Agentic AI Top 10 — including goal hijacking, tool misuse, identity abuse, memory poisoning, and rogue agent behavior — and generates compliance evidence for the EU AI Act, HIPAA, and SOC2. The toolkit supports Python, TypeScript, Rust, Go, and .NET, integrating with LangChain, CrewAI, Google ADK, and Microsoft Agent Framework via native extension points. Microsoft has stated intent to eventually move the project to a neutral OWASP foundation for community governance.

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
“This fills a real gap — most agent frameworks have no native governance layer and you're left writing your own. Sub-millisecond policy enforcement with full OWASP coverage and multi-framework support is exactly what production agent deployments need, and the multi-language support is practical.”
“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.”
“Covering 10 OWASP risks in a single toolkit means each coverage is inevitably shallow. Framework-agnostic integrations tend to have leaky abstractions, and the EU AI Act compliance mapping needs to be independently audited by actual compliance lawyers before you rely on it in regulated environments.”
“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.”
“Runtime governance for AI agents is going to be mandatory — regulatory pressure is building globally and OWASP is already defining the standard risks. Getting this infrastructure in place early and under neutral foundation governance is the right architectural bet for organizations building production agentic systems.”
“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.”
“For creative tools and non-enterprise deployments this level of governance overhead is overkill. Sub-millisecond OWASP policy enforcement is a solution for regulated industries, not indie AI apps. Skip unless you're building something with genuine enterprise compliance requirements.”
“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.”
