Base44

Create a new application using Base44's AI-powered builder. This operation is asynchronous — the app builds in the background, typically takes around 5 minutes but can take longer. IMPORTANT: After calling this tool, you MUST first respond to the user with the editorUrl from the response. Only AFTER you've sent the user the editor link, use get_app_status to poll until status is 'ready' or 'error'. All app editing is done through the Base44 Editor, not through this chat.

Edit an existing Base44 app by sending a change request to the AI builder. This operation is asynchronous — changes are applied in the background, typically takes around 5 minutes but can take longer. IMPORTANT: After calling this tool, you MUST first respond to the user with the editorUrl from the response. Only AFTER you've sent the user the editor link, use get_app_status to poll until status is 'ready' or 'error'. Further editing is done through the Base44 Editor, not through this chat.

Get the live preview URL for a Base44 app. Only returns a URL when the app build status is 'ready'. Returns null if the app is still building or has no sandbox.

Check the build status of a Base44 app. Returns one of: 'ready', 'processing', or 'error'. Use this to poll after calling create_base44_app or edit_base44_app. Poll every 30 seconds until the status is 'ready' or 'error'.

List the entity schemas (data models) defined in a Base44 app. Returns the JSON schema structure for each entity, including field names, types, and constraints. Use this to understand the data model before querying entities.

List all apps owned by the authenticated user. Always returns both app names and their IDs. Optionally filter by name.

Query entity records (rows) from a Base44 app using MongoDB-style filters. Supports filtering, sorting, pagination, and field selection. Use list_entity_schemas first to understand the available entities and their fields. Every app has a built-in 'User' entity — to list app users, query entityName='User'.
