42Crunch is the API and MCP security governance company. We help enterprises secure every interface their applications and AI agents depend on, from REST and GraphQL APIs to the Model Context Protocol (MCP) servers that give agents access to business systems. Our approach is contract-first. A machine-readable contract defines what each API or MCP server is allowed to do, and every audit, scan and runtime decision is checked against it. The result is security that developers can act on early, and evidence that auditors can rely on later. API Security Platform Audit: scores OpenAPI and GraphQL contracts at design time, with fixes inside the developer's IDE. Scan: tests live APIs for OWASP API Top 10 vulnerabilities and contract drift. Protect: enforces the contract at runtime with a lightweight micro API firewall. Govern: Security Quality Gates in CI/CD hold every team to the same standard. MCP Security Governance AI agents now call tools on their own, and unregistered MCP servers create shadow paths around enterprise controls. 42Crunch extends the same Contract, Audit, Scan and Protect model to MCP: it discovers MCP servers, generates a contract for each, scores their posture, tests them for OWASP MCP Top 10 risks such as tool poisoning, rug pulls and excessive permissions, and blocks non-compliant servers in CI/CD. Compliance evidence built in Scoring is deterministic, not judged by an LLM, so the same server or API always gets the same result. Findings map to NIST AI RMF, OWASP MCP Top 10, the EU AI Act, ISO/IEC 42001 and the CSA AI Controls Matrix, and every decision produces a versioned record that exports for auditors, regulators and customer security reviews. Built for how teams already work 42Crunch runs in developer IDEs, CI/CD pipelines and AI coding assistants such as GitHub Copilot, and integrates with Microsoft Defender for Cloud and Microsoft Sentinel. It is trusted by banks, fintechs, telcos and enterprises, and 42Crunch is ISO/IEC 27001 certified.

What is API Security software?
Compare and discover the best API Security software and tools for your team. Find the right solution for your needs. With 44 api security tools listed on Picari, you can compare features, pricing models, and real user experiences side-by-side, without speaking to a single sales rep until you're ready.
Who needs api security tools?
API Security software is typically adopted by teams that have outgrown manual processes and need repeatable, scalable workflows. You'll get the most value if:
- Your team spends more than 5 hours/week on tasks that could be automated
- You're scaling past 10 team members and need consistent processes
- You need better visibility into performance metrics and ROI
- Your current tools don't integrate well with the rest of your stack
Buying criteria checklist for api security
Before committing to a api security platform, run through this evaluation checklist:
Common mistakes when evaluating api security tools
- 1.Buying based on demos alone. A polished demo doesn't reveal how the tool handles your actual data and workflows. Always run a proof-of-concept.
- 2.Ignoring total cost of ownership. The sticker price is rarely the full cost, factor in implementation, training, integrations, and potential add-on fees.
- 3.Not involving end users in the evaluation. The people who'll use the tool daily should have a say. Top-down purchases often lead to low adoption.
- 4.Comparing too many tools at once. Shortlist 2–3 finalists max. Evaluating 5+ tools in parallel leads to decision fatigue and delayed timelines.
