Do I need the server prefix combined with my API key automatically?

Mailchimp API keys usually have a suffix (like `key-us6`). The system will parse everything internally. Just paste the full API key into our simplified authentication box naturally.

Can I bulk add 5,000 users directly in a single conversational prompt?

While structurally possible via API logic, context windows prohibit reading arrays of 5000 units. Adding is handled dynamically unit by unit securely or in exceptionally tiny batches to bypass hard egress caps effectively.

Does the system allow firing off actual live campaigns immediately to massive audiences?

No. The MCP server prioritizes safe state changes (subscribers). Launching massive destructive dispatches is omitted from the handler array to avoid rogue AI actions firing misconfigured commercial payload sets blindly.
