Introduction

wc3-forge is a native Warcraft III map editor (Go + TypeScript, a single Wails binary) with an embedded MCP server. The GUI and Claude Code talk to the same editor session — every edit you make by hand can also be made by an agent, and vice versa, and they share one undo stack.

What it does today

Read + write across most surfaces, exposed through both the GUI and MCP:

• Placed units and doodads — move / rotate / scale, plus create and delete.
• Terrain — tile and height editing.
• A full Object Editor for all 7 definition kinds: units, items, abilities, buffs, destructables, doodads, and upgrades (read + write, custom and stock).
• A complete Trigger Editor — GUI tree + Monaco code view + WC3 IntelliSense, GUI→Lua/JASS codegen, native JASS-map editing, Convert-Map-to-Lua, and Test Map.
• Saves in place, including packaged .w3x / MPQ archives.

Older JASS maps open, edit, save, and Test Map directly — no conversion required.

Why an MCP-native editor?

Most editors are built for a human at a mouse. wc3-forge is built so that the same session can be driven by a person and by Claude Code at the same time. A JSON-RPC units.move and a viewport drag end up in the same mutator and emit the same change events, so:

• Claude can read the map, reason about it, and make precise edits.
• You keep full manual control and a live view of everything the agent does.
• Both share one history stack — Ctrl+Z undoes Claude's edits and vice versa.
