Package Version Checker MCP Server

Overview

Package Version Checker is an MCP server that provides real-time access to the latest stable package versions from multiple package registries. This helps ensure that when an LLM generates code, it uses current and secure dependencies rather than outdated versions.

Installation

Using Docker (Recommended)

The easiest way to run the Package Version Checker is using Docker:

docker run -p 8080:8080 ghcr.io/sammcj/mcp-package-version:latest

You can also use the provided docker-compose file:

# Clone the repository
git clone https://github.com/sammcj/mcp-package-version.git
cd mcp-package-version

# Start the server
docker-compose up -d

Building from Source

If you prefer to build from source, you'll need Go installed:

1. Clone the repository:

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

2. Build and run:

   go build
   ./mcp-package-version
   

Configuration

The server runs on port 8080 by default. You can configure it using environment variables:

• PORT: The port to run the server on (default: 8080)
• LOG_LEVEL: Set the logging level (default: info)
• CACHE_TTL: Time to live for the cache in seconds (default: 3600)

Integrating with LLM Tools

To use this MCP server with your LLM tools, add it to your configuration:

1. For Claude/Anthropic:

   • Add the server to your Claude settings
   • Use the tools as described in the Tools section below

2. For other LLM tools that support the Model Context Protocol:

   • Configure the tool to connect to your running instance
   • The server endpoint is http://localhost:8080 (or your custom host/port)

Troubleshooting

If you encounter issues:

1. Check that the server is running and accessible
2. Verify your firewall settings allow connections to the server port
3. Check the server logs for any error messages
4. Ensure your LLM tool is properly configured to use the MCP server
