Our reading of syn.tax, from the data
syn.tax is an MCP server, 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 6 days ago (2026-10-12).
It runs as a hosted endpoint, so there is nothing to install.
