Build with the catalogue

Everything listed here is also yours to embed: ship the full index inside your app as a versioned npm package, or query the hosted API with a typed client.

@hotstack/catalogue-snapshot

v0.20260709.1 on npm

The whole catalogue, offline

Every listing in this catalogue as one versioned data package — MCP configs, plugin references, curated entries with their skills, brand logos, and removal provenance — already deduplicated and denylist-filtered. Build a plugin directory into your app with no service to run. Republished weekly.

npm i -D @hotstack/catalogue-snapshot

@hotstack/catalogue-client

v0.1.0 on npm

Typed client for the live API

A dependency-free fetch client for the catalogue API — search, entry detail, the registry feed, and per-source status, with honest degraded/stale semantics. For apps that want live search over the full index instead of a baked-in snapshot.

npm i @hotstack/catalogue-client
