Can I send messages to members through the AI agent?

Yes. The `send_message` tool sends a direct message to a member. Provide a JSON payload with the `member_id`, `content` (the message text), and `type` (message type). Use `list_members` first to find the member ID.

Can I view the full conversation history with a member?

Yes. Use `list_conversations` to see all active conversations, then `get_conversation` with a specific conversation ID to retrieve the full message thread including sender, timestamp, and content for each message.

Can I create new member profiles and manage their contact information?

Yes. Use `create_member` with a JSON payload containing `first_name`, `last_name`, `email`, `phone`, and other contact details. Use `list_members` to browse existing members and `get_member` to inspect a specific profile.
