ReferenceError: storage is not defined when running mcp.js

[Adhishtanaka]

When I try to run mcp.js in LibreSprite, I get a runtime error in the console.
It looks like the script is trying to use storage, but that variable is not defined in the environment.

Steps to Reproduce

1. Open LibreSprite (SDL build v1.2-973d0e3d).
2. Run mcp.js.
3. Observe the error console.

Error Output

ReferenceError: storage is not defined
    at _get (<anonymous>:10:9)
    at get (<anonymous>:142:9)
    at checkServerHealth (<anonymous>:182:9)
    at onEvent (<anonymous>:335:17)
    at <anonymous>:1:36

Environment

• OS: Windows 11
• LibreSprite version: v1.2-973d0e3d-SDL
• MCP script: mcp.js

Expected Behavior

The script should run without referencing an undefined variable.

Actual Behavior

Execution fails with ReferenceError: storage is not defined.

Possible Cause

The storage object might not be available in the SDL build, or it was not initialized before being used in mcp.js.

The server fully relies on LibreSprite's storage class (ref: https://github.com/LibreSprite/LibreSprite/blob/master/SCRIPTING.md#global-storage-class-storage) for communication between the tool and the MCP server. Unfortunately, I don't think there's a way around it except using a supported LibreSprite build with the storage object.

Just to double-check, can you manually run storage in the scripting console to confirm if it's actually not available (it should throw the same error), so we know it is not an issue with the script itself? Thanks!
