The server provides a tool calledsend-messagethat accepts the following parameters:
{ type: 'prompt' | 'notification', // Type of message title: string, // Message title content: string, // Message content actions?: Array<{ // Optional action buttons label: string, // Button label value: string // Value returned when clicked }>, timeout?: number // Optional timeout in milliseconds }
-
Notification: Simple message that doesn't expect a response
{ "type": "notification", "title": "Hello", "content": "This is a notification" }
Prompt: Message that waits for a response
{ "type": "prompt", "title": "Question", "content": "Do you want to proceed?", "actions": [ { "label": "Yes", "value": "yes" }, { "label": "No", "value": "no" } ], "timeout": 60000 // Optional: 1 minute timeout }
- Prompts can be answered either by clicking action buttons or sending a text message
- Only one response is accepted per prompt
- If a timeout is specified, the prompt will fail after the timeout period
- Notifications don't wait for responses and return immediately
