About

42Crunch API Security Platform provides API security testing and runtime protection, and applies contract-driven governance to MCP servers used by AI agents. Static and dynamic API tests are generated from OpenAPI definitions, with findings mapped to the OWASP API Security Top 10. Its runtime micro-firewall builds an allowlist from an API contract and blocks traffic not declared there, with stated sub-millisecond overhead. For MCP, the platform discovers servers across registries, gateways, and repositories, then generates contracts for their advertised tools, resources, and prompts. MCP security findings map to NIST AI RMF, OWASP MCP Top 10, EU AI Act, ISO/IEC 42001, and CSA AICM controls. Integration options include IDEs, CI/CD systems, Kubernetes, Docker, Postman, and MuleSoft. Individual costs $9 per month and Individual Pro costs $20 per month; an enterprise plan is listed without a price, with cloud, on-premises, or hybrid deployment options. The 14-day trial requires a corporate email and no credit card. CI/CD documentation notes that GraphQL federation is unsupported there, and Jenkins instructions say GraphQL scanning needs a separate subscription.

Who it is for

It suits teams governing OpenAPI-based APIs and MCP servers within AI-agent environments. The listed IDE, CI/CD, and deployment options may fit teams working across development pipelines and cloud, on-premises, or hybrid infrastructure.

What is good

Tests are generated from OpenAPI definitions.
Runtime micro-firewall blocks undeclared traffic.
Discovers MCP servers and generates contracts.
CI/CD documentation lists eight pipeline options.
Enterprise deployment can be cloud, on-premises, or hybrid.

What to know first

GraphQL federation is unsupported in CI/CD integration.
Jenkins GraphQL scanning requires a separate subscription.
Enterprise pricing is not listed.

Verdict

42Crunch links contract-based API testing and runtime enforcement with security governance for MCP servers. Teams relying on GraphQL federation in CI/CD should account for the stated integration limit.
