The Manuscript/Archived
The Manuscript is a curated catalog of tools and MCP servers, grouped by the job each one does, with an install line and a source link for every entry. The catalog count shown anywhere on this site is computed from the catalog source at build. An earlier version of this site printed a hand-typed figure that was wrong by a factor of eight, and that class of defect is what the computed count exists to prevent.
This volume is kept for reference and is no longer maintained, so a tool listed here may have moved, changed name or stopped being developed. It stays at its original URL. The same catalog is served as JSON at /api/catalog, and the three volumes are introduced together on the learn hub.

Honest limits
Inclusion here is not a ranking and it is not an endorsement of current quality. Each entry was checked when it was added; the volume is archived, so none of them has been rechecked since the archive date above. Follow the source link before you install anything.
