Modal

The Modal connector adapts an already-initialized Modal Sandbox from the modal JavaScript SDK into Flue’s sandbox interface. Use it for provider-backed command execution and files when your application provisions Modal sandbox resources.

Add the connector

pnpm exec flue add modal

Requirements

Requirement	Value
Provider package	modal
Runtime	Node.js 22 or later for the connector recipe’s Modal SDK use
Credentials	MODAL_TOKEN_ID and MODAL_TOKEN_SECRET
Image behavior	Choose an image with the shell/system utilities needed by your agent work

Choose this connector when

Use Modal when your application already manages Modal applications, images, or sandbox lifetimes and needs to expose that compute boundary to Flue operations. The connector adapts the created sandbox; creation, shutdown, secret handling, networking, and image content remain your responsibility.
