Tripwire MCP server

Tripwire

made by alibolly

An MCP server that gives an AI coding agent real control of Roblox Studio and Roblox Open Cloud, with a test-and-security layer no other Studio MCP has.

Tripwire lets an assistant read, write, and edit the data model, drive playtests with simulated input, run tests-as-code headlessly in the real engine, flag client-trust exploits in game code, and call the Open Cloud APIs (DataStores, MessagingService, Memory Stores, and more). The Studio tools need no API key; the headless test, asset, and Open Cloud tools use an Open Cloud key.

Requirements

• An MCP client: Claude Code, Codex, Gemini, or any client that speaks MCP over stdio.
• Roblox Studio, for the Studio tools. These need no API key.
• Node.js, only if you run the server with npx. The prebuilt binary needs no Node.
• For the headless test, asset, and Open Cloud tools: a published place and a Roblox Open Cloud API key. See Open Cloud setup.

Quickstart

Tripwire is for Roblox developers who drive Studio through an AI coding agent.

1. Wire the server into your MCP client (one command or a small config block, see Install below).
2. Install the Studio plugin so the Studio tools can reach Studio (see the plugin step in Install).
3. Open your place in Studio, turn on Game Settings > Security > Allow HTTP Requests, then click the Tripwire toolbar button and press Connect in the panel. The panel shows Connected and the Output prints [Tripwire v...] connected.
4. Ask your agent to run studio_status. A connected Studio confirms the bridge works.
5. Optional: add an Open Cloud key for the headless test, asset, and Open Cloud tools (see Open Cloud setup).

Install

Tripwire's server is a single binary. The easiest way to run it is with npx, which fetches the prebuilt binary for your platform, so there is no Rust toolchain to install. Prefer a manual binary or a source build? See the Alternatives at the end of this section.

Claude Code

One command:

claude mcp add --transport stdio tripwire -- npx -y tripwire-roblox

Or add it to a project .mcp.json (or ~/.claude.json):

{
  "mcpServers": {
    "tripwire": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "tripwire-roblox"]
    }
  }
}

Codex

Add to ~/.codex/config.toml:

[mcp_servers.tripwire]
command = "npx"
args = ["-y", "tripwire-roblox"]

Or: codex mcp add tripwire -- npx -y tripwire-roblox

Gemini

Add to ~/.gemini/settings.json (or a project .gemini/settings.json):

{
  "mcpServers": {
    "tripwire": {
      "command": "npx",
      "args": ["-y", "tripwire-roblox"]
    }
  }
}

Or: gemini mcp add tripwire npx -y tripwire-roblox

Other MCP clients

Any client that speaks MCP over stdio can run it:

command: npx
args:    ["-y", "tripwire-roblox"]

Alternatives: prebuilt binary, or build from source

Prebuilt binary (no Node). Download the archive for your platform from the Releases page (for example tripwire-server-vX.Y.Z-aarch64-apple-darwin.tar.gz), extract it, and point your client's command at the extracted tripwire-server with empty args.
