ProofLayer
What it is
ProofLayer helps teams scan AI code before deployment, test AI systems with automated attacks and protect MCP traffic at runtime. Its open-source scanner can examine coding agents, MCP servers, prompts, skills, code and packages from a workstation, CI workflow or as an MCP tool. It flags risks such as prompt injection, exposed secrets, unsafe MCP tools, hallucinated packages and vulnerable generated code. Autonomous campaigns test LLM applications, multi-agent systems, RAG pipelines and MCP servers for issues including jailbreaks, data exfiltration, tool abuse, RAG poisoning and memory injection. Verified breaches include replay traces and audit-ready evidence. Runtime checks cover MCP risks such as tool poisoning, excessive permissions, unsafe execution and supply-chain issues. Listed targets include OpenAI, Anthropic, Azure OpenAI, self-hosted Qwen, Llama and Mistral, along with LangGraph, LangChain, ChromaDB and MCP servers. ProofLayer says it generates evidence for SOC 2, NIST AI RMF, the EU AI Act and ISO/IEC 42001. Its free Community plan includes a CLI and MCP scanner, more than 1,700 detection rules, prompt-injection probes, MCP tool testing and a community rule library.
For and against
For
- Free Community scanner is CLI- and MCP-enabled
- Includes more than 1,700 detection rules
- Automated campaigns cover multiple AI system types
- Verified breaches include replay traces and audit evidence
- Lists SaaS or VPC deployment
Against
- Access is described as private preview
- Enterprise red-teaming and compliance features are not in the free plan
The verdict
ProofLayer covers pre-deployment scanning, automated red-teaming and runtime MCP checks, with a free scanner for smaller teams.
Who it suits
The free Community plan is aimed at individual developers and small teams that want a CLI and MCP security scanner. Enterprise is positioned for teams with dedicated red-teaming and compliance needs.
