Integrations

  • Provides tools for checking AWS Bedrock AI models, including searching, listing, and getting information about available models

  • Provides tools for checking available tags for Docker container images from Docker Hub

  • Provides tools for checking available tags for container images from GitHub Container Registry (ghcr.io)

Package Version MCP Server

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: As of version 2.0.0, mcp-package-version has been rewritten in Go, as such the configuration needs to be updated in your client - see the Installation section for more details.

Installation

Requirements:

Using go install (Recommended for MCP Client Setup):

go install github.com/sammcj/mcp-package-version/v2@HEAD

Then 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

Other Installation Methods

Or clone the repository and build it:

git clone https://github.com/sammcj/mcp-package-version.git cd mcp-package-version make

You can also run the server in a container:

docker run -p 18080:18080 ghcr.io/sammcj/mcp-package-version:main

Note: 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", } } }
Tip: Go Path

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 $GOPATH

The go install command downloads and compiles Go packages, placing the resulting binary executable in the bin subdirectory of your $GOPATH. By default, $GOPATH is > usually located at $HOME/go on Unix-like systems (including macOS). If you haven't configured $GOPATH explicitly, Go uses this default.

The location $GOPATH/bin (e.g., /Users/your_username/go/bin) needs to be included in your system's PATH environment 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 $GOPATH to the default if it's not already set, and ensure $GOPATH/bin is in your PATH:

[ -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.

Usage

The server supports two transport modes: stdio (default) and SSE (Server-Sent Events).

STDIO Transport (Default)

mcp-package-version

SSE Transport

mcp-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!).

Command-line Options
  • --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

Docker images are available from GitHub Container Registry:

docker pull ghcr.io/sammcj/mcp-package-version:main

You can also see the example docker-compose.yaml.

Releases and CI/CD

This project uses GitHub Actions for continuous integration and deployment. The workflow automatically:

  1. Builds and tests the application on every push to the main branch and pull requests
  2. Creates a release when a tag with the format v* (e.g., v1.0.0) is pushed
  3. Builds and pushes Docker images to GitHub Container Registry
