Our reading of Cyber Library, from the data

Cyber Library is a notes & knowledge MCP server, listed in the official MCP Registry.

We haven't measured its tool list yet, so its token cost is unknown.

Maintenance is active: the last public signal was 7 days ago (2026-10-11). For comparison, 71% of notes & knowledge servers are active or maintained.

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