Package Version Check MCP Server

# package-version-check-mcp

A MCP server that returns the latest stable versions of packages you use as dependencies in a variety of ecosystems, such as Python, NPM, Go, or GitHub Actions.

It also supports looking up the latest versions of almost 1000 tools, such as **development runtimes** like `python`, `node`, `dotnet`, **development tools** like `gradle`, and various **DevOps tools** like `kubectl` or `terraform`, via the [mise-en-place](https://mise.jdx.dev/) tool.

## Why do I need this?

Whenever an AI coding agents generates files that pin dependency versions, they insert **outdated versions** because their training happened weeks or months ago, and new dependency versions have been released since then. As a developer, it is annoying having to manually fix these outdated versions.

This MCP fixes this problem. Use it together with an MCP such as [Context7](https://context7.com/) to avoid that your AI agent produces outdated code.

## Features

Supported ecosystems / tools:
- Developer ecosystems:
  - **NPM** - Node.js packages from registry.npmjs.org
  - **PyPI** - Python packages from PyPI
  - **NuGet** - .NET packages from NuGet
  - **Maven / Gradle** - Java/Kotlin/Scala packages from Maven repositories (Maven Central, Google Maven, etc.)
  - **Go** - Go modules from proxy.golang.org
  - **PHP** - PHP packages from Packagist (used by Composer)
  - **Ruby** - Ruby gems from rubygems.org
  - **Rust** - Rust crates from crates.io
  - **Swift** - Swift packages from GitHub repositories
  - **Dart** - Dart packages from pub.dev
- DevOps ecosystems:
  - **Docker** - Docker container images from Docker registries
  - **Helm** - Helm charts from ChartMuseum repositories and OCI registries
  - **GitHub Actions** - Actions hosted on GitHub.com, returning their current version, their inputs and outputs, and (optionally) their entire README with usage examples
  - **Terraform _Providers_ and _Modules_** - Providers & Modules from Terraform Registry, OpenTofu Registry, or custom registries
  - Various _tools_ such as `kubectl`, `terraform`, `gradle`, `maven`, etc. supported by mise-en-place

## Usage

### Adding the MCP to Your Agent

There are three ways to make this MCP available to your AI coding agent:

#### Option 1: Use the Hosted Service (Easiest)

Point your agent to the free hosted service:
```
https://package-version-check-mcp.onrender.com/mcp
```
in (streamable) HTTP mode.

This is the quickest way to get started. Note that the hosted service may have rate limits from the underlying package registries.

#### Option 2: Run with uvx (for local use)

Use `uvx` to run the MCP server locally:
```bash
uvx package-version-check-mcp --mode=stdio
```

This automatically installs and runs the latest version from PyPI.

**Requirements:**
- You need the `mise` binary on PATH if you want to call the tools `get_supported_tools` or `get_latest_tool_versions`

**Optional but recommended:** Set the `GITHUB_PAT` environment variable to a GitHub Personal
