OpenAPI Consumer Breakage Gate

Catch consumer-breaking MCP tool contract changes before agents break. Compare HTTPS tool catalogs to a baseline and export Dataset findings, SUMMARY, SARIF, and JUnit for CI or schedules.

Compare two OpenAPI 3.0/3.1 specs (JSON or YAML) and emit per-endpoint / per-operation / per-schema change rows with a `breaking` flag. Pairs with the api-response-delta-monitor.

Monitor OpenAPI JSON/YAML specifications and output structured breaking/non-breaking API change records.

Monitor public OpenAPI specs for removed paths, operations, operation IDs, and security schemes.

Audit one inline OpenAPI 3.0 or 3.1 document. Get a bounded deterministic score, operation inventory, and machine-readable contract findings without remote URL fetching.

OpenAPI Example Runner

junipr/openapi-example-runner

Extract and run safe bounded examples from OpenAPI specs and report pass/fail results.

OpenAPI Spec Diff Auditor

junipr/openapi-spec-diff-auditor

Diff OpenAPI specs for breaking changes, added or removed endpoints, required parameters, response drift, and schema compatibility. by default.

Convert OpenAPI and Swagger specs into LLM-ready endpoint Markdown, API reference JSONL, schema summaries, and agent context.

Turn OpenAPI 3.x or Swagger operations into agent-ready tool names, input schemas, response schemas, auth and risk metadata.

Openapi To Mcp Converter
