Our reading of Nan, from the data

Nan is a memory MCP server from luciferfran.

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, 68% of memory servers are active or maintained.

With 12 GitHub stars it ranks #304 of 1,597 memory servers we index.

It runs locally on your machine over stdio.
