**Roslyn-enriched C# exception telemetry for Godot Engine, exposed over MCP.**
---
What is Wick?
When a Godot C# game crashes, your AI assistant sees a raw stack trace and spends 8+ turns asking you to open files. Wick captures that exception, enriches it with Roslyn-powered source context (the actual method body, caller chain, recent logs, scene state), and hands the full picture to the AI in one call. **One turn to diagnosis instead of ten.**
What makes Wick different?
Other Godot MCP servers (like the excellent GoPeak) focus on scene manipulation and GDScript tooling. Wick focuses on the C#/.NET developer experience:
- **Roslyn-enriched exception telemetry** -- stderr-captured C# exceptions enriched with the calling method body, surrounding source lines, enclosing type, and caller chain. No other Godot MCP server does this.
- **In-process exception capture** -- optional Wick.Runtime NuGet companion catches TaskScheduler.UnobservedTaskException and async exceptions that stderr can't see.
- **Build diagnostics with source context** -- dotnet build errors enriched with Roslyn source context through the same pipeline as runtime exceptions.
- **C# analysis tools** -- find symbol, find references, member signatures via Roslyn workspace.
- **5-pillar tool group system** -- activate only what you need: core, runtime, csharp, build, scene.
Getting Started
Prerequisites
- .NET 10 SDK (10.0.201 or later)
- Godot 4.6.1+ with .NET/Mono support
Installation
Wick has two parts: a Godot-side bridge addon (/addons/wick/) and the .NET MCP server.
**Godot bridge** — install via the Godot Asset Library in-editor (recommended), or copy /addons/wick/ into your project manually.
**MCP server** — clone and build:
MCP Configuration
Add Wick to your AI coding assistant's MCP configuration:
Tool Groups
Activate tool pillars via WICK_GROUPS env var or --groups CLI flag:
| Pillar | What it includes | Default |
|---|---|---|
| core | GDScript tools, scene parsing, GDScript LSP, introspection | Always on |
| runtime | Exception pipeline, game launch/stop, log tail, runtime_diagnose | Opt-in |
| csharp | Roslyn analysis, find symbol, find references, member signatures | Opt-in |
| build | dotnet build/test/clean, NuGet management, build_diagnose | Opt-in |
| scene | Scene create/modify via headless Godot dispatch | Opt-in |
Example: WICK_GROUPS=core,runtime,csharp,build or --groups=all.
Optional: Wick.Runtime Companion
For in-process exception capture (async exceptions, TaskScheduler.UnobservedTaskException) and live scene-tree queries, add the Wick.Runtime NuGet companion to your Godot C# project:
Wire both Install() and Tick() into your game's entry point — both are required:
> **If your in-process bridge tools (runtime_query_scene_tree, etc.) hang forever, you forgot Tick().** Install() alone covers exception capture, but live RPC handlers need Tick() to drain the main-thread dispatcher. See docs/getting-started.md and the package README for the full story.
