What is the OpenAPI Validator Engine MCP Server?

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.

Built-in capabilities (1)

validate_openapi

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

FAQ

Frequently asked questions

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.

How do I add an MCP server to Claude Code?

Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.

Can Claude Code run MCP tools in headless mode?

Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.

How do I list all connected MCP servers?

Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
