WolvenKit MCP — Cyberpunk 2077 Modding Tools

MCP server that gives Claude Code access to WolvenKit for Cyberpunk 2077 modding. Extract archives, convert game files to JSON, inspect meshes and textures, manage mods, and build mod projects — all from your terminal.

Works offline (no game running needed). Pairs with CET MCP for a complete AI-assisted modding pipeline.

How it works

Claude Code → stdio/JSON-RPC → MCP Server → WolvenKit CLI (cp77tools) → filesystem
