Manage app records - Niblet Docs

MCP manages the record around an app, not its source code. Build, validate, preview, and upload revisions with the Niblet CLI on your computer.

What each tool does

Tool	Purpose
`app_list`	List your developer projects
`app_get`	Read one project and its immutable revision history
`app_create`	Create an app record before the first CLI upload
`app_update`	Change the public name, summary, and description
`app_submit_for_review`	Submit an uploaded revision for review

Plan the app

Ask the assistant to help refine the name, public app handle, listing copy, data sources, and settings.

Build locally

Create and edit source on your system. Run niblet apps validate and niblet apps preview until the result is ready.

Push with the CLI

Run niblet apps push .. The CLI creates the project when needed and uploads an immutable source-and-preview pair.

Inspect and submit with MCP

Call app_get to confirm the revision, then use app_submit_for_review with its revision UUID.

Submitting through MCP starts the same review as niblet apps submit. It never grants direct publication access.
