About 42Crunch
What is 42Crunch?
42Crunch is an API security platform that automates security controls for APIs, with a specific focus on securing AI agent workflows. It provides guardrails from the design and development phase through to runtime protection, ensuring that AI agents interact with enterprise APIs securely.
What problem does it solve?
As AI coding agents and agentic workflows increasingly generate and consume APIs at machine speed, traditional security measures can't keep up. 42Crunch addresses this by providing deterministic guardrails, validating requests, and automating remediation of vulnerabilities. It bridges the gap between development and runtime security, helping security teams maintain governance over their API ecosystem.
Who is it for?
42Crunch is built for security and development teams in enterprises that are adopting AI agents and need to secure their API infrastructure. It's ideal for organizations using coding agents like Claude Code or Copilot, and those who need to expose existing business services to AI safely. It is not for individual developers looking for a simple API testing tool.
Real-world use cases
Common use cases include scanning APIs for vulnerabilities (SAST & DAST), ensuring OpenAPI contract governance, blocking attacks on production APIs, and securing MCP (Model Context Protocol) servers. It enables organizations to move fast with agentic AI without sacrificing security, governance, or auditability.
Key features
- API Security Audit & Scan — Automate vulnerability scanning (SAST & DAST) for your APIs across the development lifecycle.
- Design & Dev Time Guardrails — Enforce OpenAPI contract governance and security quality gates during the build process.
- Runtime Security Quality Gates — Validate and authorize every request, blocking AI-to-API threats in real time.
- Secure MCP Server — Secure AI agent access to APIs with a policy-driven abstraction layer that evolves with MCP standards.
- AI to API Threat Blocking — Immediately stop ongoing AI attacks on your API-driven applications.
- Automated Remediation — Automate remediation and redeployment of vulnerable APIs to prevent further outages.
- Auditability & Accountability — Gain clear visibility into agent activity with auditable execution trails for compliance.
