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.

ElevenAgents Guardrails 2.0 is a safety layer built on top of ElevenLabs' voice agent platform, designed for enterprises deploying customer-facing AI voice agents at scale. The core problem it solves: voice agents in production tend to drift, get manipulated through prompt injection, or go off-brand in ways that only surface after something embarrassing happens. Version 2.0 adds three main capabilities: real-time policy enforcement that monitors agent behavior as it happens, prompt injection protection against users trying to manipulate the agent's instructions, and configurable custom rules that enterprises can tailor to their specific compliance or brand requirements. Unlike static guardrails baked into the system prompt, these operate as a live enforcement layer during conversations. The timing matters. As more enterprises put voice agents on their phone lines and websites, the "what could go wrong" list has gotten longer — agents giving wrong pricing, going off-script with sensitive customers, or being jailbroken into saying things they shouldn't. Guardrails 2.0 positions ElevenLabs not just as a voice synthesis platform but as an enterprise-safe agent runtime.
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.”
“Static system prompt guardrails are a band-aid. Having a live enforcement layer that can catch drift and injection attempts as they happen is the right architecture for anything customer-facing. This is the kind of tooling that makes it reasonable to deploy voice agents in sensitive contexts like healthcare or finance.”
“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.”
“Guardrails as a paid add-on to your voice agent platform is a strange model — safety shouldn't be upsold. Also, ElevenLabs controlling both the voice synthesis and the safety layer means there's no independent verification that the guardrails are actually working. That's a dangerous single point of trust for enterprise compliance purposes.”
“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.”
“Voice agents are the new customer service reps, and companies are learning the hard way that they need guardrails. This is the beginning of a whole category: real-time behavioral safety systems for AI agents. The team that solves this at scale — across providers, not just ElevenLabs — will be enormous.”
“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.”
“Brand safety for voice is genuinely underserved. Written AI outputs can be reviewed and filtered; voice interactions happen in real time with no undo. Knowing your agent won't say something off-brand to a live customer is worth paying for, especially for high-volume contact centers.”
