Membrane Universe

Membrane Universe gives self-hosted instances access to the same library of connectors, apps, and actions available on Membrane Cloud. Your self-hosted instance fetches these elements from the Membrane Cloud API on demand.

Configuration

Membrane Universe requires two environment variables on the API service:

Variable	Description	Example
`SELF_HOSTING_TOKEN`	Your self-hosting token. Generate from your organization settings.	`sht_abc123...`
`CLOUD_API_URL`	Membrane Cloud API URL.	`https://api.getmembrane.com`

Both variables must be set for Membrane Universe to be enabled.

Available Elements

When Membrane Universe is enabled, the following elements from Membrane Cloud become available on your self-hosted instance:

Connectors — pre-built connectors with their auth specs, operations, and data collections. Available automatically.
External Apps — the full app catalog with logos, categories, and metadata. Available automatically.
Actions — pre-built actions from app packages. Requires the Enable Action Packages workspace setting (see below).

Enable Action Packages

The Enable Action Packages setting in workspace settings controls whether pre-built actions from app packages appear in action listings.

Connectors and external apps are available automatically regardless of this setting. Actions require it because they are loaded from public packages, which may affect the number of elements shown in listings.
