Open Source Python Tool Fixes Roblox Studio MCP Handshake Issues

Kars_32 · reddit · 2026-08-14

While trying to get Roblox Studio MCP working with an agent (Antigravity), the author encountered several issues with the official setup.

To resolve this, they developed a lightweight Python wrapper that fixes the MCP handshake and properly handles the Studio connection. Additionally, they identified a batch syntax error in the official mcp.bat file: MCP server fails to start if the Windows path contains spaces (such as a username).

The fix tool is open-sourced on GitHub for other developers facing the same issues.
