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.

Shannon is an autonomous AI security research agent from Keygraph that takes a target (web app, API, or codebase) and runs a full offensive security workflow: static analysis, attack surface mapping across OWASP Top 10, and then actual proof-of-concept exploit execution — all without manual intervention. It orchestrates real security tools (Nmap, Subfinder, SQLMap, Playwright) under the hood, not just generating reports. The Lite tier (AGPL-3.0) handles web apps and API endpoints, running browser automation and fuzzing attacks autonomously. Shannon Pro (commercial) adds SAST/SCA integration, CI/CD pipeline hooks for PR scanning, and team-level finding management. The model layer is pluggable — defaults to GPT-4o for planning with Claude Sonnet for exploit reasoning, but can be pointed at local models. What sets Shannon apart from tools like Burp Suite or ZAP is the agentic loop: it doesn't just surface a list of potential issues, it attempts exploitation and logs what worked. For small security teams and solo founders doing pre-launch security checks, this compresses days of pentesting work into a single automated run. The open-source Lite tier is the real news here — genuine autonomous exploitation capability, freely available.
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 paying $400/month for a pentesting retainer for pre-launch checks. Shannon Lite ran against my staging environment and surfaced an actual SQLi vulnerability in 20 minutes that my last manual audit missed. The AGPL license means I can self-host it in my CI pipeline without worrying about data leaving my network.”
“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.”
“Autonomous exploitation tools have serious dual-use liability. The AGPL license doesn't prevent anyone from running Shannon against systems they don't own — and AI-generated PoC exploits at this speed are a real threat multiplier for less-sophisticated attackers. I'd want to see proper authorization checks and rate limiting baked into the Lite tier before recommending this broadly.”
“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.”
“Security tooling is going through the same shift coding did with Copilot — autonomous agents are going to make pentesting accessible to every small team that currently can't afford it. Shannon is an early version of what eventually becomes a background daemon watching your entire attack surface 24/7.”
“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.”
“Less relevant to my workflow directly, but I've started including 'ran Shannon against my portfolio site' in client pitches as a trust signal. The fact that indie creators can now point a professional-grade security tool at their own work without a $5K budget is a shift worth noting.”
