Our reading of InboxMCP, from the data

InboxMCP is a communication MCP server from breakcold, listed in the official MCP Registry.

Its endpoint requires sign-in or an API key just to list tools, so we haven't measured its token cost; we never use real credentials.

With 0 GitHub stars it ranks #344 of 858 communication servers we index.

It runs as a hosted endpoint, so there is nothing to install.
