EOL MCP Server 📅

A Model Context Protocol (MCP) server that enables AI assistants like Claude to check software end-of-life (EOL) dates and support status using the endoflife.date API. This helps AI models provide accurate information about software lifecycle and security status in real-time.

What is MCP? 🤔

The Model Context Protocol (MCP) is a system that lets AI apps, like Claude Desktop, connect to external tools and data sources. It provides a standardized way for AI assistants to work with local services and APIs while keeping the user in control.

What does this server do? 🚀

The EOL MCP server:

Checks software end-of-life dates and support status
Scans for CVE vulnerabilities in software versions
Provides version comparison and upgrade recommendations
Supports natural language queries about software lifecycle
Handles multiple software products (Python, Node.js, Ubuntu, etc.)
Caches recent queries for quick reference

Example Conversations 💬

Basic Version Check:

Human: Is Python 3.8 still good to use?
Claude: Let me check the status of Python 3.8.
[Uses check_version tool]
Based on the EOL data, Python 3.8:
- Security support ends: October 2024
- Current status: Security fixes only
Recommendation: Consider upgrading to Python 3.11 for new projects.

Security Analysis:

Human: Any security concerns with Node.js 16?
Claude: I'll analyze the security status of Node.js 16.
[Uses check_version tool]
[Uses check_cve tool]
Found:
- Support Status: LTS until September 2023
- Critical CVEs: 2 in last 6 months
- CVSS Score Range: 7.5-9.8
Recommendation: Update to latest 16.x patch or consider Node.js 18 LTS.

Version Comparison:

Human: Which Ubuntu version should I use?
Claude: I'll help you compare Ubuntu versions.
[Uses version-comparison prompt]
Analysis:
- 22.04 LTS: Supported until 2027, recommended for new deployments
- 20.04 LTS: Supported until 2025, stable and widely used
- 18.04 LTS: Approaching EOL, plan migration
Recommendation: Use 22.04 LTS for best long-term support.

Prerequisites 📋

Before you begin, ensure you have:

Node.js (v18 or higher)
Claude Desktop installed
Git installed

You can verify your Node.js installation by running:

node --version  # Should show v18.0.0 or higher

Installation 🛠️

Clone the repository:

git clone https://github.com/ducthinh993/mcp-server-endoflife
cd mcp-server-endoflife

Install dependencies:

npm install

Build the project:

npm run build

Create a global link:

npm link

Configuration ⚙️

1. Claude Desktop Configuration

Configure Claude Desktop to recognize the EOL MCP server:

For macOS:

code ~/Library/Application\ Support/Claude/claude_desktop_config.json

For Windows:

code %APPDATA%\Claude\claude_desktop_config.json

Add the EOL server configuration:

{
  "mcpServers": {
    "eol": {
      "command": "npx",
      "args": ["/path/to/eol-mcp-server/build/index.js"]
    }
  }
}

2. Restart Claude Desktop

For the changes to take effect:

Completely quit Claude Desktop (not just close the window)
Start Claude Desktop again
Look for the 🔌 icon to verify the EOL server is connected

Troubleshooting 🔧

Common Issues

Server Not Found
- Verify the npm link is correctly set up
- Check Claude Desktop configuration syntax
- Ensure Node.js is properly installed
API Issues
- Check if endoflife.date API is accessible
- Verify the API response format hasn't changed
- Check network connectivity
Connection Issues
- Restart Claude Desktop completely
- Check Claude Desktop logs:
  # macOS tail -n 20 -f ~/Library/Logs/Claude/mcp*.log
