The record

What it does: ProofLayer scans AI code before deployment, red-teams agents continuously, and protects MCP traffic at runtime, turning findings into audit-ready evidence.
Coding agent scanner: The open-source scanner checks coding agents, MCP servers, prompts, skills, code, and packages from a developer workstation, CI, or as an MCP tool.
Scanner coverage: The scanner flags prompt injection, hallucinated packages, exposed secrets, unsafe MCP tools, and vulnerable generated code.
Red teaming: Autonomous attack campaigns test LLM applications, multi-agent systems, RAG pipelines, and MCP servers; verified breaches include replay traces and audit-ready evidence.
Attack classes: Campaigns test prompt injection, jailbreaks, data exfiltration, tool abuse, RAG poisoning, and memory injection.
Integrations and targets: Listed targets include OpenAI, Anthropic, Azure OpenAI, self-hosted Qwen/Llama/Mistral, LangGraph, LangChain, ChromaDB, and MCP servers.
Runtime integrations: The MCP runtime security page lists LangChain, OpenAI Agents SDK, CrewAI, AutoGen, Semantic Kernel, and Pydantic AI integrations.
Runtime protection: MCP runtime security tests for tool poisoning, prompt injection, excessive permissions, unsafe tool execution, data exfiltration, and supply-chain risk.
Compliance evidence: ProofLayer says it generates evidence for SOC 2, NIST AI RMF, EU AI Act, and ISO/IEC 42001.
Enterprise features: The Enterprise plan lists continuous autonomous red-teaming, proof-of-exploit reports, SSO/SAML, SLA guarantees, a CISO executive portal, dedicated support and onboarding, and custom attack scenarios.
Deployment options: The pricing comparison lists ProofLayer deployment as SaaS or VPC and access as private preview.
Intended users: The Community plan is described for individual developers and small teams; the Enterprise plan is positioned for dedicated red-teaming and compliance needs.
