Replay-verified minimal JSON reproductions and deterministic TypeScript/OpenAPI drift checks. Local-first CLI and MCP server.

Zero-API OpenAPI 3.0 & 3.1 Breaking Change & Schema Drift Detector GitHub Action & CLI

Diff two MCP tools/list snapshots: added / removed / modified tools, with breaking-change detection (removed tools, added required fields, removed properties, type changes). Markdown changelog + JSON output + --strict CI gate.

Self maintaining API migration agent that detects API drift, analyzes affected code, generates migration patches, runs tests, and verifies changes automatically before creating a PR.

api-spec-generator - static Flask archaeology: OpenAPI 3.1 from legacy code plus API drift detection. ast-only, never imports user code.

Generate a publishable n8n community node from prose API docs, plus a conformance test that catches vendor API drift.

Codex skill for consumer-side third-party API drift detection.

Know when the APIs, LLMs and MCP servers you depend on go down — or silently change. Self-hosted API contract & drift monitoring.

Detects drift in the third-party APIs your AI agents depend on, explains it, warns your agents over MCP, and opens the pull request that adapts your code.

The weather report for the APIs the internet runs on: zero-infrastructure API contract monitoring with GitHub Actions and api-drift. Fork it to watch your own.
