SkyrimCK-MCP

A Model Context Protocol (MCP) server that lets Claude Code create and edit Skyrim SE ESP/ESM files without opening Creation Kit. Built primarily to make the Creation Kit accessible to blind modders: describe what you want in plain language and Claude writes the ESP directly — records, subrecords, VMAD, ALPC, CTDA conditions, PACK templates, scenes, aliases, SNDR/SOUN, CELL overrides, etc.

Why

Creation Kit's GUI is unusable with screen readers. This project replaces it with Claude Code + a thin C# server that drives the esper library (by matortheeternal, author of zEdit / Mator Smash, built on xEdit record definitions).

The first real use case is the autowalk ESP for SkyrimNVDA — a full accessibility plugin that uses this ESP for its pathfinding feature.

Requirements

  • .NET 8.0 SDK
  • Skyrim SE (for testing the generated ESPs)
  • Papyrus Compiler (ships with the Creation Kit or Skyrim AE install)

Setup

This repo depends on two external libraries that need to be cloned alongside it:

git clone https://github.com/Pyrhame/SkyrimCK-MCP.git
cd SkyrimCK-MCP
git clone https://github.com/matortheeternal/esper.git
git clone https://github.com/matortheeternal/balsa.git
dotnet build src/SkyrimCkMcp.csproj

The esper/ and balsa/ directories are not committed here — they're full upstream clones you should keep updated independently.

What it can build

  • QUST (quests with VMAD, aliases, ALPC, DNAM, scripts)
  • PACK (Travel packages, template-based, with CTDA conditions)
  • SCEN (scenes with phase markers)
  • SNDR / SOUN (custom sounds, with proper Papyrus-compatible wrapping)
  • CELL overrides (with REFR overrides, Initially Disabled flags)
  • PKDT / PSDT / ALPC / VMAD binary subrecords

Most of the sharp edges (e.g. SOUN wrapping required for Papyrus Sound type, GetFormFromFile vs GetForm, VMAD v2 Object format, template-based Travel packages) are documented in CLAUDE.md.

Status

Alpha. Works for the SkyrimNVDA autowalk use case and some basic quest/sound records. Many record types are still unsupported.
