Overview

AI-generated overview

Lets an assistant list scanned GitHub repos, run API-change scans, and open reviewable auto-fix pull requests through Versionly.

What it does: Versionly watches third-party APIs in the GitHub repositories you connect. Through its MCP tools an assistant can list scanned repos, run scans, and open auto-fix pull requests that map breaking changes to affected files. It also provides a skill for monitoring vendor API changes from chat. Pull requests are opened for team review rather than merged automatically.
When to use it: Useful when your project depends on third-party APIs and you want an assistant to surface breaking changes and prepare fix pull requests for review. Best suited to teams already using Versionly and GitHub repositories they control.
Requirements: A remote MCP endpoint at mcp.versionly.dev; no local package or runtime is needed. You authenticate the Versionly MCP connector when your client prompts, and connect repositories in the Versionly web app. The auto-fix pull request tools are listed as a paid plan feature.

Before you install

The server connects to your GitHub repositories and can open pull requests, so review what it writes before merging. Auto-fix pull request tools require a paid plan, so usage may incur cost. Authentication is handled through the Versionly connector and app rather than declared keys or headers.
