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.

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
“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.”
“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.”
“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.”
“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.”
“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.”
“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.”
“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.”
“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.”
