Server

You know how spinning up internal dev environments with proper HTTPS is always a pain? This handles the certificate authority side of that problem. It lets Claude create and manage CA certificates, sign server certs, and handle the whole PKI dance so your local services can run with valid TLS. Reach for this when you're setting up internal tools, development clusters, or self-hosted services that need trusted certificates without paying for or exposing them to public CAs. It's the streamable HTTP transport flavor, so it runs as a web service rather than locally. Saves you from manually running openssl commands or writing your own CA scripts every time you need to issue another cert.
