Installation

ChEddi is installed like any other TYPO3 extension. All required dependencies, in particular the AI Suite and the MCP server, are installed automatically and do not have to be added separately.

1. Install extension via Composer

composer require autodudes/cheddi

Steps in the backend

Activate the extension. It ships its own database tables, so run the database compare afterwards.
Grant the permission. The backend groups concerned need the right “Enable Chat Interface”. Without it the chat is not injected at all, see Permissions.
Check the model permissions. Every group additionally needs the right for at least one chat-capable model. Without it the model selection stays empty and the input area shows a hint.

Clear all caches afterwards.

No API key of its own

The server address and the API key are not stored with ChEddi, they are read from the AI Suite configuration (aiSuiteServer and aiSuiteApiKey), including the per-backend-group overrides.

Without the API key the chat does not start a turn. The input area stays locked and shows the same hint as the AI Suite module.
