Our reading of HorizonX, from the data
HorizonX is an MCP server from mdx2025, 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.
Maintenance is active: the last public signal was in the last day (2026-10-17).
It runs as a hosted endpoint, so there is nothing to install.
