TLS Radar MCP Server

Independent monitoring from a vendor that doesn't sell certificates - built for the 90-day-cert era, where manual renewal tracking is already finished. It is available as a remote MCP endpoint.

Teams that work with acme, certificate monitoring and certificates and want a hosted endpoint instead of running a local process. The project is written in Python.

    "tls-radar-tlsradar-claude-plugin": {
      "url": "https://tlsradar.com/api/v1/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
