SSLMon

You deploy an MCP server that provides domain registration information and SSL certificate monitoring. This enables you to track domain expiration life cycles and SSL validity across your infrastructure, helping you stay compliant and secure.

How to use

Connect to sslmon MCP to look up domain details and SSL certificate status from your MCP client. Use the remote HTTP endpoint for centralized queries or run a local NPX-based server for ad-hoc or isolated testing. You can retrieve domain registration and expiration dates, along with SSL certificate validity periods, issuer, and subject, to monitor risk and plan renewals.

How to install

Prerequisites: you need Node.js installed on your machine. You also need an MCP client that can connect to an HTTP MCP server or run a local stdio MCP server.

Option 1: Use the remote HTTP MCP server from a client. This does not require running a local server.

Option 2: Run a local NPX-based MCP server for testing or development.

# NPX (Local MCP server) - add to your MCP client as a local server
# If you are configuring via a client, you can reference the local NPX-based server as shown below.

Configuration and usage notes

There are two explicit ways to connect to the MCP server depending on your setup.

HTTP remote MCP server configuration (preferred method): you connect to the remote endpoint at the given URL and use the MCP client to query tools like domain info and SSL info.

Environment and tools overview

The server exposes two primary tools you can use via MCP clients:

Available tools

get_domain_info

Retrieve domain registration and expiration information for a given domain, including registration date, expiration date, registrar, registrant, status, and days until expiry.

get_ssl_cert_info

Retrieve SSL certificate information for a domain, including validity period, issuer, subject, and whether the certificate is currently valid, plus days until expiry.
