Common questions

Is Warcraft III Map Tools safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 2 days ago, and the latest version (0.5.40) reached the registry 2 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB, Node.js on your computer.

What can I use instead?

wc3-mcp

Made by GodMephisto

An MCP server that lets AI assistants such as Claude read, audit and edit Warcraft III .w3x and .w3m maps byte-faithfully (files you do not touch keep their bytes).

It is the MCP server of wc3ctl, which also has a command line tool and a desktop editor. Install wc3ctl if you want those as well. It carries the same server as wc3ctl mcp serve.

What you need

64-bit Windows. The game data reader (CascLib) is a Windows library.
Warcraft III Reforged, only for the tools that read base game data. Map tools work without it.
Any AI app that speaks MCP. Nothing else, the release carries its own .NET.

Install

Open PowerShell and run

irm https://raw.githubusercontent.com/GodMephisto/wc3-mcp/main/install.ps1 | iex

That downloads the latest release, checks its SHA-256, unpacks it into %LOCALAPPDATA%\Programs\wc3-mcp, adds that folder to your PATH and sets up every supported AI app it finds. No admin rights. Run the same line again to update. Restart your AI app afterwards.

Prefer to do it by hand? Download the zip from the Releases page, unzip it into any folder you like, then from that folder run

.\wc3-mcp.exe install --all

The setup records wherever the exe actually is, so any folder works. It also adds that folder to your user PATH once, so from then on plain wc3-mcp works in any new terminal. Pass --no-path to skip that, and use .\wc3-mcp.exe from its folder instead.

Using Claude Desktop only? Download wc3-mcp- -win-x64.mcpb from the Releases page and double-click it. Claude Desktop installs it as an extension. Its one setting, the Warcraft III folder, can stay empty to have the install detected. The server is also listed in the MCP Registry as io.github.GodMephisto/wc3-mcp, for apps that install from there.

Context and RAG

Out of the box the server answers docs_search from the bundled Warcraft III references, the Big UI-Frame Tutorial and the Editor Ability Insight doc, lexical and offline, and serves each whole as an MCP resource.

For the full corpus and semantic search, install the local index. From your AI app, call the rag_install tool, or from a shell

wc3ctl rag install

It fetches two files, once, and verifies each against a pinned digest. The embedding model BAAI/bge-small-en-v1.5, about 130 MB, and the corpus, about 61 MB from this repo's dataset-v1 release. It then builds a local vector index and a graph. No database, no service, no key, and it is set low on CPU by default. After that docs_search is semantic and the graph tools graph_neighbors, graph_hubs and graph_path are live. wc3ctl rag status reports what is installed.

Set up your AI app

These need wc3-mcp on your PATH, which the one-line install and the first wc3-mcp.exe install both arrange. Until then, run them as .\wc3-mcp.exe ... from the folder the exe is in.

wc3-mcp install --all            set up every supported app found on this PC

wc3-mcp install cursor vscode set up only the apps named wc3-mcp uninstall --all remove it again wc3-mcp config print the settings to paste by hand wc3-mcp clients list supported apps and whether each is set up wc3-mcp doctor check the install, the game folder and the apps

App	Name to use	Where it is written
Claude Code	`claude-code`	through `claude mcp add --scope user`
Claude Desktop	`claude-desktop`	`%APPDATA%\Claude\claude_desktop_config.json` (Store build too)
Cursor	`cursor`	`%USERPROFILE%\.cursor\mcp.json`
VS Code (GitHub Copilot)	`vscode`	`%APPDATA%\Code\User\mcp.json`
Windsurf	`windsurf`	`%USERPROFILE%\.codeium\windsurf\mcp_config.json` or `%APPDATA%\devin\mcp_config.json`
Gemini CLI	`gemini`	`%USERPROFILE%\.gemini\settings.json`
Codex CLI	`codex`	`%CODEX_HOME%` or `%USERPROFILE%\.codex\config.toml`
Cline	`cline`	`cline_mcp_settings.json` in VS Code's storage for Cline
LM Studio	`lmstudio`	`%USERPROFILE%\.lmstudio\mcp.json`
Zed	`zed`	`%APPDATA%\Zed\settings.json`

Setup only changes the one wc3 entry. Every other server and setting in the file stays as it was, and the file is copied to NAME.wc3-mcp.bak first. A file with comments in it (common in Zed and VS Code) is never rewritten, because that would delete the comments. The settings to paste are printed instead.

Any other MCP app

It is a standard stdio MCP server. Point your app at wc3-mcp.exe with no arguments. wc3-mcp config cursor prints a ready-made JSON entry with the real path filled in, which most apps accept as is.

Configuration

The Warcraft III folder is found automatically from the Windows registry, then C:\Warcraft III, C:\Program Files (x86)\Warcraft III and C:\Program Files\Warcraft III. When yours is somewhere else, either

install with wc3-mcp install --all --game-dir "D:\Games\Warcraft III", which sets WC3_GAME_DIR in each app's entry, or
pass game_dir to a single tool call.

A game_dir argument wins over WC3_GAME_DIR, which wins over the automatic search. wc3-mcp doctor shows which folder it is using.

Build from source

In PowerShell, with the .NET 8 SDK installed,

git clone https://github.com/GodMephisto/wc3-mcp

cd wc3-mcp dotnet test --filter "Category!=Corpus&Category!=GameData&Category!=Doctor" dotnet publish src/Wc3.Mcp/Wc3.Mcp.csproj -c Release --self-contained -r win-x64 -o dist-mcp .\dist-mcp\wc3-mcp.exe install --all

The apps then start the exe inside your clone's dist-mcp folder, and that folder is what goes on your PATH, so keep the clone where it is or rerun the last line after moving it.

Exact SDK and package versions are in REQUIREMENTS.md. CascLib.dll must stay beside wc3-mcp.exe.
