SSL Certificate Check — Claude Code MCP server: how to install
A hosted MCP server that inspects SSL/TLS endpoints. It checks certificate expiration dates, covered hostnames, and accepted TLS versions directly inside your coding agent.
claude mcp add --transport http ssl-certificate-check https://powmcp.com/ssl-certificate-check/mcpWhat SSL Certificate Check does
This server registers the ssl_check tool in your agent workflow. When invoked against an address, it retrieves the live certificate to inspect expiration timing, verify which domain names are covered, and see which TLS handshake versions the server permits.
PowMCP runs the service as a remote hosted endpoint over Streamable HTTP. You do not need to clone source files or run background Node or Python processes on your workstation. The backend implementation itself is proprietary, while descriptor files and setup documentation use the MIT license.
Because this connects via Streamable HTTP, your editor or CLI client must support remote HTTP MCP servers.
What it helps with
- inspect certificate expiration on a target endpoint
- check hostname coverage across domain certificates
- identify supported TLS versions for an external service
- audit endpoint encryption without terminal utilities
Example prompts for the agent
- Check the TLS certificate on
api.example.comand report when it expires. - Use
ssl_checkto see ifauth.mycompany.orgallows TLS 1.3. - Verify the hostname coverage for the certificate served by
portal.test.

Questions about SSL Certificate Check
How do I install SSL Certificate Check in Claude Code?
Run claude mcp add --transport http ssl-certificate-check https://powmcp.com/ssl-certificate-check/mcp in your terminal.
What does SSL Certificate Check do?
It provides the ssl_check tool to analyze live endpoint certificates. The tool reports expiration dates, covered domain names, and supported TLS versions.
Does this server require local installation?
No local runtime is required. PowMCP hosts the server remotely over HTTP, so your client only needs network access to the endpoint URL.
