Implementation Reference
- src/index.ts:162-167 (handler)The handler function that executes the tool logic: extracts projectName and message from arguments, sends an OS notification using node-notifier, and returns a confirmation response.(args) => { // Use inferred args type const { projectName, message } = args; notifier.notify({ title: projectName, message }); return { content: [{ type: 'text', text: 'Notification sent.' }] }; },
- src/index.ts:155-169 (registration)Registration of the message_complete_notification tool using server.tool(), including dynamic description handling, schema reference, and inline handler function.server.tool( 'message_complete_notification', // Description is a string here, but handle consistently typeof messageCompleteNotificationTool.description === 'function' ? messageCompleteNotificationTool.description(globalTimeoutSeconds) // Should not happen based on definition, but safe : messageCompleteNotificationTool.description, messageCompleteNotificationTool.schema, // Use schema property (args) => { // Use inferred args type const { projectName, message } = args; notifier.notify({ title: projectName, message }); return { content: [{ type: 'text', text: 'Notification sent.' }] }; }, ); }
- Zod schema (raw shape) defining input parameters: projectName and message, used for input validation.const rawSchema: ZodRawShape = { projectName: z.string().describe('Notification title'), message: z.string().describe('Notification body'), };
- ToolCapabilityInfo including JSON schema for parameters (input schema advertised to MCP client).const capabilityInfo: ToolCapabilityInfo = { description: 'Notify when a response has completed via OS notification.', parameters: { type: 'object', properties: { projectName: { type: 'string', description: 'Identifies the context/project making the notification (appears in notification title)', }, message: { type: 'string', description: 'The specific notification text (appears in the body)', }, }, required: ['projectName', 'message'], }, };
- src/tool-definitions/message-complete-notification.ts:72-76 (registration)Export of the ToolDefinition object aggregating capability, description, and schema, imported and used for registration in index.ts.export const messageCompleteNotificationTool: ToolDefinition = { capability: capabilityInfo, description: registrationDescription, schema: rawSchema, // Use the raw shape here };
