Package Version Check Mcp

This server solves a specific pain point in AI-assisted coding: agents trained on older data will confidently insert outdated dependency versions into your package.json, requirements.txt, or Dockerfile. It exposes tools to check latest versions across npm, PyPI, Maven, Go modules, Docker images, Helm charts, GitHub Actions, Terraform providers, and about a dozen other ecosystems. The get_latest_package_versions tool handles batch lookups and returns version numbers plus digests where available. There's also get_github_action_versions_and_args for fetching action metadata with inputs and outputs. You can run it via the hosted HTTP endpoint, locally with uvx, or as a Docker container. Cache configuration is available to reduce registry API calls during longer sessions.
