# Versionly

> Versionly is self-maintaining API software for engineering teams. It monitors third-party HTTP APIs, detects breaking OpenAPI and changelog changes, maps impact to GitHub repositories you connect, and opens reviewable auto-fix pull requests. It never merges by itself.

Versionly is a product of WoWSQL Technologies Private Limited (India). GitHub App access is scoped to repos you choose. The npm SDK is `@wowsql/sma`. Hosted MCP lives at https://mcp.versionly.dev/mcp for Cursor and ChatGPT.
