An MCP server that provides tools for checking latest stable package versions from multiple package registries:
- npm (Node.js/JavaScript)
- PyPI (Python)
- Maven Central (Java)
- Go Proxy (Go)
- Swift Packages (Swift)
- AWS Bedrock (AI Models)
- Docker Hub (Container Images)
- GitHub Container Registry (Container Images)
- GitHub Actions
This server helps LLMs ensure they're recommending up-to-date package versions when writing code.
IMPORTANT: I'm slowly moving across this tool to a component of my mcp-devtools server
Requirements:
- A modern go version installed (See Go Installation)
Using go install (Recommended for MCP Client Setup):
go install github.com/sammcj/mcp-package-version/v2@HEADThen setup your client to use the MCP server. Assuming you've installed the binary with go install github.com/sammcj/mcp-package-version/v2@HEAD and your $GOPATH is /Users/sammcj/go/bin, you can provide the full path to the binary:
{
"mcpServers": {
"package-version": {
"command": "/Users/sammcj/go/bin/mcp-package-version"
}
}
}- For the Cline VSCode Extension this will be
~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json - For Claude Desktop
~/Library/Application\ Support/Claude/claude_desktop_config.json - For GoMCP
~/.config/gomcp/config.yaml
Or clone the repository and build it:
git clone https://github.com/sammcj/mcp-package-version.git
cd mcp-package-version
makeYou can also run the server in a container:
docker run -p 18080:18080 ghcr.io/sammcj/mcp-package-version:mainNote: If running in a container, you'll need to configure the client to use the URL instead of command, e.g.:
{
"mcpServers": {
"package-version": {
"url": "http://localhost:18080",
}
}
}If $GOPATH/bin is not in your PATH, you'll need to provide the full path to the binary when configuring your MCP client (e.g. /Users/sammcj/go/bin/mcp-package-version).
If you haven't used go applications before and have only just installed go, you may not have a $GOPATH set up in your environment. This is important for any go install command to work correctly.
Understanding
$GOPATHThe
go installcommand downloads and compiles Go packages, placing the resulting binary executable in thebinsubdirectory of your$GOPATH. By default,$GOPATHis > usually located at$HOME/goon Unix-like systems (including macOS). If you haven't configured$GOPATHexplicitly, Go uses this default.The location
$GOPATH/bin(e.g.,/Users/your_username/go/bin) needs to be included in your system'sPATHenvironment variable if you want to run installed Go binaries directly by name from any terminal location.You can add the following line to your shell configuration file (e.g.,
~/.zshrc,~/.bashrc) to set$GOPATHto the default if it's not already set, and ensure$GOPATH/binis in yourPATH:[ -z "$GOPATH" ] && export GOPATH="$HOME/go"; echo "$PATH" | grep -q ":$GOPATH/bin" || export PATH="$PATH:$GOPATH/bin"After adding this line, restart your terminal or MCP client.
The server supports two transport modes: stdio (default) and SSE (Server-Sent Events).
mcp-package-versionmcp-package-version --transport sse --port 18080 --base-url "http://localhost:18080"This would make the server available to clients at http://localhost:18080/sse (Note the /sse suffix!).
--transport,-t: Transport type (stdio or sse). Default: stdio--port: Port to use for SSE transport. Default: 18080--base-url: Base URL for SSE transport. Default: http://localhost
Docker images are available from GitHub Container Registry:
docker pull ghcr.io/sammcj/mcp-package-version:mainYou can also see the example docker-compose.yaml.

}This project uses GitHub Actions for continuous integration and deployment. The workflow automatically:
- Builds and tests the application on every push to the main branch and pull requests
- Creates a release when a tag with the format
v*(e.g.,v1.0.0) is pushed - Builds and pushes Docker images to GitHub Container Registry
