Secure AI-generated APIs by immediately fixing code generated by Claude Code, GitHub Copilot, Cursor, Windsurf, and beyond.
Guardrails for code from
AI coding agents such as Claude Code, GitHub Copilot, Cursor, and Windsurf can scan source code, generate OpenAPI contracts, and now remediate their own work automatically — a real unlock for developer productivity and time to market. But as those agents connect to tools and business services through the Model Context Protocol (MCP), they stop being code generators and start executing business logic directly through APIs. Most MCP gateway implementations are built for connectivity, not control — without strong authentication, fine-grained authorization, and runtime policy enforcement, AI agents introduce a new, largely ungoverned attack surface.
42Crunch brings its proven API security platform into the agentic AI era, so APIs generated, remediated, and executed by AI agents stay secure at every stage. The moment an agent generates or modifies an API, 42Crunch's guardrails kick in autonomously — auditing the OpenAPI contract, remediating vulnerabilities directly inside the coding agent or IDE workflow, deploying the implementation, and running dynamic security tests against the live API.
For security and engineering leaders, this means:
Guardrails run at Design, Dev, Build, and Production — not bolted on after the fact.
Baked into every AI-assisted build, not a separate manual step someone has to remember to run.
API contract issues and vulnerabilities get fixed directly in code, in the same feedback loop the agent already works in.
One enterprise-wide API security policy enforced across every AI-assisted build, from every agent.
Audit of the OpenAPI specification and automatically remediate any blocking issues.
Automatically scan and remediate API code for vulnerabilities with 42Crunch.
AI-generated APIs raise the risk bar because they're created at high speed and scale, often without validation against security policy, and used directly by AI agents to execute business logic — with none of the consistent governance or audit trail a regulator or security team expects. That creates a new execution layer for AI systems that most teams haven't accounted for yet.
Missing or weak authentication, excessive data exposure, poor schema validation, injection vulnerabilities, business logic flaws, and inconsistent API contracts (OpenAPI drift) — plus AI-specific risks like hallucinated endpoints and unsafe tool usage, because agents optimize for functionality first, not security.

AI coding agents such as Claude Code, GitHub Copilot, and Codex can generate APIs quickly but may also introduce vulnerabilities. Guardrails ensure APIs are secure at design, validated during build, and controlled at runtime.
An MCP server enables AI agents to connect to tools and APIs, but without security controls it can introduce risks such as unauthorized access and data leakage. A secure MCP server acts as a governed control layer that validates, enforces, and audits all AI-to-API interactions.
AI-generated APIs increase risk because they're created at high speed and scale (amplifying vulnerabilities), often not validated against security policies, directly used by AI agents to execute business logic, and lacking consistent governance and auditability — creating a new attack surface where APIs become the execution layer for AI systems.
Commonly: missing or weak authentication (APIs exposed without proper access control), excessive data exposure, poor schema validation, injection vulnerabilities from a lack of input sanitization, business logic flaws, inconsistent API contracts (OpenAPI drift), and AI-specific risks such as prompt-driven misuse or hallucinated endpoints. These arise because AI agents prioritize functionality over security and don't follow enterprise security standards by default.
