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 💬

  1. 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.
  1. 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.
  1. 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:

You can verify your Node.js installation by running:

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

Installation 🛠️

  1. Clone the repository:

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

npm install
  1. Build the project:

npm run build
  1. 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:

  1. Completely quit Claude Desktop (not just close the window)

  2. Start Claude Desktop again

  3. Look for the 🔌 icon to verify the EOL server is connected

Troubleshooting 🔧

Common Issues

  1. Server Not Found

    • Verify the npm link is correctly set up

    • Check Claude Desktop configuration syntax

    • Ensure Node.js is properly installed

  2. API Issues

    • Check if endoflife.date API is accessible

    • Verify the API response format hasn't changed

    • Check network connectivity

  3. Connection Issues

    • Restart Claude Desktop completely

    • Check Claude Desktop logs:

      # macOS tail -n 20 -f ~/Library/Logs/Claude/mcp*.log
