Our reading of Custom Domain API, from the data
Custom Domain API is an MCP server from sireto, listed in the official MCP Registry.
We haven't measured its tool list yet, so its token cost is unknown.
It runs locally on your machine over stdio and needs one secret (CUSTOM_DOMAIN_API_KEY); use a scoped, least-privilege key.
