About 42Crunch

42Crunch sells a platform for governing the security of MCP servers, APIs and AI agents at enterprise scale. 42Crunch says it helps enterprises bring AI security under control. 42Crunch describes the job as discovering every MCP server that AI agents expose or consume, securing each one against attack, and assessing compliance with AI regulations and security frameworks.[4][10]

42Crunch says AI coding agents ship MCP servers faster than any manual inventory process can track. 42Crunch discovers every MCP server across an organization automatically, both sanctioned and shadow alike, audits each one and ranks it by risk. 42Crunch says every request from an AI agent passes through the MCP server before it ever reaches an enterprise system or the API behind it. 42Crunch also says an MCP tool is only as secure as the API it wraps.[4]

42Crunch says its deterministic contract-driven model applies equally to the MCP and API layer. Every MCP server and every API behind it gets a machine-readable contract of its declared surface. In the 42Crunch model, discovery writes the contract, testing measures against it, and runtime enforces it. 42Crunch says the model it uses to secure APIs now extends to the MCP servers AI agents call and expose.[4][6]

On the MCP side, 42Crunch sweeps registries, gateways and repos to surface the shadow servers agents are already calling, then reads each server's advertised tools, resources and prompts and emits a contract. Every finding carries severity, evidence and the fix. 42Crunch fails the build when a server leaves its approved contract, then keeps watching the one in production for new tools, rewritten descriptions and widened permissions.[4]

Tests are generated from the OpenAPI definition and run in the pipeline, covering broken object-level authorization, broken auth, mass assignment and unrestricted resource consumption. All AI generated code is automatically fixed by 42Crunch. For runtime, 42Crunch describes a positive-security firewall assembled from the contract itself, where unknown paths, extra parameters, malformed payloads and over-sharing responses are rejected before they reach the backend.[4]

For compliance, 42Crunch says the EU AI Act, ISO 42001, NIST AI RMF, CSA AICM and OWASP are all tagged automatically on every audit. A security review doubles as compliance evidence without extra work. Each finding arrives already tied to the control it answers, so the audit trail for an AI estate is a by-product of the scan. 42Crunch computes compliance posture control by control on every audit and every scan, not assembled from documents afterward. Each audit and scan checks a server against all applicable frameworks at the same time.[4][5][11]

A server below the threshold does not reach production.[12]

42Crunch is built for enterprise security and platform teams governing MCP servers, APIs and AI agent security at scale. 42Crunch pairs API Audit, Scan and Protection with MCP Contract, Audit, Scan and Protect on one platform, with one set of SQG policies and one CI/CD pattern. Pricing includes a dedicated encrypted tenant, SSO and a dedicated support manager, sized to the number of APIs, MCP servers and users. Individual developers who use the 42Crunch AI coding agent plugins have a self-serve pricing option.[2][3][4][5][6][7][10][12]
