What is the 42Crunch MCP Server?
Connect your 42Crunch account to any AI agent to continuously test, audit, and secure your API lifecycle through natural conversation. Say goodbye to manual spec uploads and cumbersome dashboard navigations.
What you can do
- API Collections — List and view your organizational API collections, evaluating their aggregated security scores
- API Management — Import OpenAPI/Swagger definitions directly into collections, list imported definitions, or delete them when decommissioned
- Static Security Audits — Trigger fresh static security audits over your OpenAPI specifications and retrieve comprehensive audit reports scoring design risks
- Dynamic Conformance Scans — List historical scans and retrieve detailed execution reports highlighting undocumented behavior or implementation flaws
How it works
- Subscribe to this server
- Enter your 42Crunch API Token
- Start managing your API security governance from Claude, Cursor, or any MCP-compatible client
Who is this for?
- DevSecOps Engineers — integrate security audits seamlessly and ask for immediate remediation steps for OWASP vulnerabilities
- Platform Teams — govern your microservices ecosystem, track security hygiene across collections, and spot uncompliant endpoints
- Backend Developers — quickly import a new spec iteration, trigger a scan, and compare the security grade evolution without context switching

Frequently asked questions
Can my AI agent explain the vulnerabilities found in a 42Crunch audit?
Yes. After retrieving an audit report using your agent, you can ask the agent to act as a DevSecOps engineer. It can break down exactly why you received a low score, explain specific OWASP findings, and write the YAML or JSON patch needed to fix your OpenAPI spec instantly.
How do I test a new API update before merging?
Simply paste your updated OpenAPI definitions into your AI agent's chat context. Ask the agent to import the new API definition into a staging collection. The platform will automatically run a static security audit upon import, and your agent can report back the new security score before you hit merge.
What is the difference between static audits and dynamic conformance scans?
Audits strictly verify the design of your JSON/YAML contract against security best practices without making network calls. Scans, however, send live HTTP traffic against your implemented endpoint to make sure your back-end truly conforms to what you wrote. Your agent can retrieve both reports for side-by-side comparison.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your 42Crunch MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
