This MCP server provides a specialized engine for auditing OpenAPI 3.x specifications. It automates the detection of critical errors through several specialized tools. Use validate_meta_schema to ensure the document adheres to the fundamental structural rules of the OAS. The detect_orphaned_components tool identifies reusable components like schemas that are defined but never referenced in paths. With verify_path_parameter_consistency, you can catch mismatches between path templates and parameter definitions. Finally, audit_response_and_requirement_integrity checks for missing response definitions and undocumented required fields within schemas.

Available Tools

validate_meta_schema, detect_orphaned_components, verify_path_parameter_consistency, and audit_response_and_requirement_integrity.

Are there any unused components in this specification?

Yes, the following orphaned components were detected: Schemas/User, Parameters/AuthHeader.

Check for path parameter errors in the provided spec.

The validator found a mismatch in path `/users/{id}` because the `{id}` parameter is missing its definition in the parameters section.

Verify that all required fields are properly defined in the schemas.

The audit found one error: property 'email' is listed as required in 'UserSchema' but is not defined in the properties object.

It performs structural checks using `validate_meta_schema`, finds unused components with `detect_orphaned_components`, and verifies path parameters. Tools available: `your_tool_name`.
