AI Song Generator

The Challenge: Music Assets for Content Creation

Creating a fitting song for a short video, podcast, or brand campaign traditionally involves significant budget and production timelines. Independent creators and small teams often face a dilemma: opt for generic stock music that lacks uniqueness, or find custom composition services prohibitively expensive. The AI Song Generator skill addresses this by enabling rapid iteration of musical directions from a simple Chinese-language description.

Core Capabilities and Workflow

The skill centers around a local CLI (Command Line Interface) tool named aimv, integrated with the Sponge Music backend service. The workflow is as follows:

1. Initialization & Connection: The first run requires aimv init. This generates a unique connection page link. After you log in via the browser (new users are registered automatically), paste the returned API Key back into the conversation, and the Agent completes the setup. The Key is long-term and only needed once.
2. Description & Generation: Use the aimv song create command with your creative brief. For example: aimv song create "An upbeat Chinese pop song about urban nights, with a touch of jazz." You can also specify parameters for mood, style, etc.
3. Retrieving Results: After generation, the CLI outputs links for audio preview, download options, and a project URL pointing to the management page on lexuan.club. All works are synced to your Sponge Music account.

Important Note: This tool relies on network API calls. If you encounter connectivity issues in a restricted environment (e.g., certain Agent sandboxes), you can set the environment variable AIMV_FORCE_CURL=1 to switch transmission to the system's curl. When the CLI is completely unusable, you can also directly use curl to interact with its HTTP API for the full cycle.

Use Cases and Boundaries

Ideal Scenarios:
* Quickly generate original song sketches from a single Chinese idea to explore chorus hooks or arrangement styles.
* Create custom-feel background music for short videos, podcast intros, etc.
* Serve as an initial inspiration source for brand or event theme songs.

Please note its boundaries:
* The skill produces AI music based on model capabilities, which may differ from deeply customized work by professional musicians.
* All operations require connection to the Sponge Music service. Your account's points and membership status affect generation quotas and permissions. Errors like insufficient_points or quota_limited will return links for top-up or membership upgrade.
* It is a local CLI tool, not an MCP server. The Agent should operate it by executing node /bin/aimv.js ... or by invoking the registered aimv tool, rather than registering it as an MCP stdio service.
