Package Version Check Mcp
Ask your coding agent for the latest PyPI, npm, Go module, Docker image, or Helm chart versions while upgrading dependencies or scaffolding a new service.
Overview
package-version-check-mcp is a MCP server for the Build phase that returns the latest versions of Python, npm, Go, Docker, Helm, and related packages on demand.
What is this MCP server?
- Resolves latest versions across Python (PyPI), npm, Go, Docker, and Helm from one MCP server
- Stdio MCP transport via PyPI package package-version-check-mcp v1.1.0
- Optional GITHUB_PAT avoids GitHub unauthenticated rate limits when metadata is fetched from GitHub
- PACKAGE_VERSION_CACHE_ENABLED toggles caching for repeated version checks in long agent sessions
- Server schema version 1.1.0
- Single PyPI package with stdio transport
- Covers Python, npm, Go, Docker, and Helm ecosystems per catalog description
Community signal: 5 GitHub stars.
What problem does it solve?
Agents and builders routinely recommend stale dependency versions because registry lookups are tedious to do by hand in the middle of a coding session.
Who is it for?
Solo builders bumping dependencies across polyglot repos who want one MCP call instead of opening five registry tabs.
Skip if: Teams that need licensed vulnerability scanning, license compliance reports, or automated PR bots like Dependabot as their primary workflow.
What do I get? / Deliverables
After you register the server, your agent can cite up-to-date package and image versions while it writes upgrade diffs and setup instructions.
- Latest published version strings for requested packages or images
- Agent-ready answers usable in lockfile and Dockerfile edits
- Reduced duplicate lookups when PACKAGE_VERSION_CACHE_ENABLED is true

Journey fit
Dependency freshness decisions happen while you are wiring stacks and bumping lockfiles, before you ship or operate in production. Version lookups are an integration/DevOps task tied to package registries and container ecosystems, not a standalone testing or launch activity.
How it compares
Registry version lookup MCP, not a security audit skill or full dependency graph analyzer.
