FAQ from VIBE-BLOCKS-MCP-FOR-ROBLOX-STUDIO

What is VIBE-BLOCKS-MCP-FOR-ROBLOX-STUDIO?

It is a tool that bridges Roblox Studio and AI-assisted editors using the Model Context Protocol, allowing AI agents to read and modify a live Roblox Studio session.

Which AI editors or models does it support?

It works with any MCP client that supports Server-Sent Events (SSE), such as Cursor, Windsurf, or future versions of Claude Desktop. No specific model is required.

Is there a cost to use it?

The README does not mention any pricing; the project appears to be open-source and free to use.

Do I need a Roblox API key?

Only for optional Open Cloud features (DataStores, asset uploading, cloud Luau execution, publishing). For basic Studio interaction, no API key is needed.

What are the known limitations?

Cloud tools require a valid API key and proper permissions. The companion plugin polls localhost:8000/plugin_command; changing the server port requires updating the SERVER_URL in the plugin script and rebuilding. Some cloud tools (get_asset_details, list_user_assets) are marked as not implemented.
