OpenAPI Validator Engine

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

Why Windsurf?

Windsurf's Cascade agent chains multiple OpenAPI Validator Engine tool calls autonomously. query data, analyze results, and generate code in a single agentic session. Paste Vinkius Edge URL, reload, and all 1 tools are immediately available. Real-time tool feedback appears inline, so you see API responses directly in your editor.

  • Windsurf's Cascade agent autonomously chains multiple tool calls in sequence, solving complex multi-step tasks without manual intervention

  • Purpose-built for agentic workflows. Cascade understands context across your entire codebase and integrates MCP tools natively

  • JSON-based configuration means zero code changes: paste a URL, reload, and all 1 tools are immediately available

  • Real-time tool feedback is displayed inline, so you see API responses directly in your editor without switching contexts

FAQ

Frequently asked questions

01

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.

02

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.

03

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.

04

How does Windsurf discover MCP tools?

Windsurf reads the mcp_config.json file on startup and connects to each configured server via Streamable HTTP. Tools are listed in the MCP panel and available to Cascade automatically.

05

Can Cascade chain multiple MCP tool calls?

Yes. Cascade is an agentic system. it can plan and execute multi-step workflows, calling several tools in sequence to accomplish complex tasks without manual prompting between steps.

06

Does Windsurf support multiple MCP servers?

Yes. Add as many servers as needed in mcp_config.json. Each server's tools appear in the MCP panel and Cascade can use tools from different servers in a single flow.

07
