MCP Certificate Monitor

Monitor SSL/TLS certificate expiry across your domains by asking Claude — no dashboards, no command-line tools.

Prerequisites

• uv installed
• Claude Desktop installed

Setup

1. Add the server to your Claude Desktop config

Open the Claude Desktop configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Add the following:

{
  "mcpServers": {
    "cert-monitor": {
      "command": "uvx",
      "args": ["mcp-certificate-monitor"]
    }
  }
}

uvx downloads and runs the package automatically — no cloning or installation step needed.

2. Restart Claude Desktop

After saving the config file, restart Claude Desktop. The server starts automatically when Claude needs it.

3. Verify the connection

Open a new conversation in Claude Desktop and ask:

What certificate monitoring tools do you have available?

Claude should describe the tools exposed by this server (check certificate, add host, scan all, etc.).

Alternative: run from source

If you prefer to run from a local clone:

git clone https://github.com/natesilva/mcp-certificate-monitor
cd mcp-certificate-monitor

Then use this config instead:

{
  "mcpServers": {
    "cert-monitor": {
      "command": "uv",
      "args": ["run", "mcp-certificate-monitor"],
      "cwd": "/path/to/mcp-certificate-monitor"
    }
  }
}
