Local and network file transfer, FTP, FTPS and SFTP are built into Grid's File/FTP source and destination nodes and need no catalog. See Interfaces and Core Nodes.

The catalog is cloned into a staging area and validated before anything is installed. Once it is in, its adapters appear in the Builder's node palette and can be filtered by catalog. Full walkthrough: Subscribing to a Catalog.
Every catalog operation — subscribing, updating and removing — needs the Administration-tier Manage catalogs permission. See Users and Roles.

Libraries in this catalog
Shared Lua modules the adapters depend on. Grid installs the version an adapter pins automatically when you build a node from it — there is nothing to install by hand.
| Library | Version | What it does |
|---|---|---|
aws_s3 | 1.0.0 | AWS S3 client — Signature V4 signing, put/get/head/delete/list, ListObjectsV2 parsing, retry and backoff. Works against S3-compatible services too. |
A published library version is never changed. A fix ships as a new version, and each node stays pinned to the version it was built against, so updating a catalog cannot disturb a node already running.
Credentials
Every adapter here ships with its credential fields empty, deliberately. Password fields are encrypted with your own grid's key, so a value shipped from the repository could not be decrypted on your machine. Enter yours on the node after you build it, leave Live Mode off for the first run, and keep Verify TLS on.
