Validate openapi on OpenAPI Validator Engine
Pass the spec as a JSON string. The engine validates against the official OpenAPI JSON Schemas and returns all errors with paths. Supports Swagger 2.0, OpenAPI 3.0, 3.1, and 3.2. Validates OpenAPI/Swagger specifications (2.0, 3.0.x, 3.1.x, 3.2.x) offline. Returns version, validity, and detailed error list
What the OpenAPI Validator Engine MCP Server unlocks
Your agent is about to generate an SDK from an OpenAPI spec. But the spec has a missing $ref, an invalid schema type, and a path parameter that doesn't match the URL template. The generated code compiles but crashes at runtime. Nobody finds it until production.
This MCP validates OpenAPI/Swagger specifications against the official JSON Schema before any code generation happens. It catches every structural error with the exact path where it occurred.
The Superpowers
- 4 Versions: OpenAPI 2.0 (Swagger), 3.0, 3.1, and 3.2 — auto-detected.
- Exact Error Paths: Each error includes the JSON pointer (e.g. paths./users.get.responses.200.content) for surgical fixes.
- Local: No external API calls. The validation schema is embedded.
- Quality Gate: Use as a CI/CD gate — reject code generation from invalid specs.
Frequently asked questions about the OpenAPI Validator Engine MCP Server
Which OpenAPI versions does it support?
Swagger 2.0, OpenAPI 3.0.x, OpenAPI 3.1.x, and OpenAPI 3.2.x. The version is auto-detected from the spec.
Does it validate $ref references?
Yes. The validator checks that all $ref pointers resolve to existing schema definitions. Missing or circular references are reported as errors.
Can I use this as a CI/CD quality gate?
Absolutely. If isValid is false, block code generation and SDK publishing. The error paths pinpoint exactly what to fix.
