Implementation Reference
- src/index.ts:1140-1159 (handler)The handler function that implements the core logic for the 'extend_audio' tool. It validates input, makes a POST request to the '/extend' API endpoint with the audio URL and optional extension duration/webhook, and returns a status message with task details.
private async handleExtendAudio(args: any) { if (!args.audio_url) { throw new McpError(ErrorCode.InvalidParams, "audio_url is required"); } const response = await this.axiosInstance.post("/extend", { audio_url: args.audio_url, extension_duration: args.extension_duration, webhook_url: args.webhook_url, }); return { content: [ { type: "text", text: `Audio extension started!\n\n${JSON.stringify(response.data, null, 2)}\n\nUse get_conversion_by_id with the task_id to check the status.`, }, ], }; } - src/index.ts:445-466 (schema)The tool schema definition including name, description, and input schema for 'extend_audio', used for tool listing and validation.
