About 42Crunch
42Crunch is a security platform for AI agents and APIs. It finds the MCP servers that agents use, checks them for risk and helps prove compliance with AI security rules.
What it does
The platform scans an organisation for MCP servers, including ones that were set up without approval. Each server is audited and ranked by risk, and findings are mapped to frameworks such as the EU AI Act, ISO 42001, NIST AI RMF and the OWASP MCP Top 10. Every MCP server and the APIs behind it are described by a machine-readable contract. Testing measures the running system against that contract, and runtime enforcement applies the rules when an agent calls a tool. The result is one place where agent requests are checked before they reach internal systems.
Key features
- Find MCP servers that AI agents use, including unapproved ones
- Rank MCP servers by risk after an automatic audit
- Map findings to the EU AI Act, ISO 42001 and NIST AI RMF
- Test APIs against machine-readable contracts
- Enforce security rules at runtime between agents and APIs
Who it's for
Security teams, enterprise IT teams and API teams that are rolling out AI agents will find it relevant. Compliance staff can also use the mapped evidence during audits.
Pricing and good to know
A free MCP security assessment is offered as a way to start. Beyond that, the platform is sold to organisations, so pricing depends on the scope of the rollout and will need a sales conversation. Governance tools like this work best when the team already keeps an inventory of its APIs and agents.
