It runs as a remote server. In Claude Code: claude mcp add --transport http certguard 'https://certguard.mike-tusa.workers.dev/mcp' --header 'Authorization: <Optional. '\''Bearer <key>'\'' (free cg_ key) for higher limits. Works without a key.>'. For other clients, paste the JSON configuration from this page into their MCP settings.

Who maintains CertGuard?
