dex-mcp
Debug and inspection tooling for Roblox projects, exposed as an MCP server so an AI agent can explore the instance tree, read/write properties, call remotes, and run Luau in a Roblox client driven by an executor.
Repository: https://github.com/972jesko/dex-mcp
Intended use: debugging, inspecting, and learning from your own Roblox projects locally. See GUIDELINES.md.
Install
npm install
npm run buildRun
node dist/index.jsOn startup the server prints (to stderr) the local WebSocket URL and a shared token. The Luau bridge connects to that URL. Configure your MCP client to launch node /absolute/path/to/dist/index.js over stdio.
Configuration (environment variables)
Variable | Default | Purpose |
|
| WebSocket hub port |
| auto-generated | Shared token required by the bridge |
|
| Enable |
|
| Enable remote calling/spying |
|
| Enable |
|
| Per-request timeout |
The bridge
The Luau bridge that runs inside the executor is documented in its own plan/spec. It connects to the printed WebSocket URL and answers the RPC protocol in docs/superpowers/specs/2026-06-07-dex-mcp-design.md §4.
