Implementation Reference
- src/index.ts:854-873 (handler)The handler function that implements the core logic for the 'create_cover_song' tool. It validates inputs, makes a POST request to the MusicGPT API '/cover' endpoint, and returns the task details with instructions for status checking.
private async handleCreateCover(args: any) { if (!args.audio_url || !args.voice_id) { throw new McpError(ErrorCode.InvalidParams, "audio_url and voice_id are required"); } const response = await this.axiosInstance.post("/cover", { audio_url: args.audio_url, voice_id: args.voice_id, webhook_url: args.webhook_url, }); return { content: [ { type: "text", text: `Cover song creation 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:164-181 (schema)The input schema defining parameters for the create_cover_song tool: required audio_url and voice_id, optional webhook_url.
