kremis vs unity-mcp
kremis: Kremis is a deterministic knowledge graph MCP server written in Rust. It provides a local, single-binary solution for recording, associating, and retrieving knowledge without relying on LLMs. The system ensures determinism, inspectability, and grounding through ACID transactions and BLAKE3 hashing.; unity-mcp: MCP for Unity integrates AI assistants like Claude and VS Code Copilot with the Unity Editor using the Model Context Protocol. This allows developers to use Large Language Models to manage assets, control scenes, edit scripts, and automate various tasks within Unity, streamlining game development workflows.

TL;DR

AI agent memory via MCP
unity-mcpDev Tooling · ★ 15.3k
When to choose:
- You develop games in Unity and want AI assistants (Claude, Cursor) to manage assets, inspect hierarchy, edit C# scripts, and run Editor commands via MCP.
- You want to automate scene setup, prefab creation, and repetitive Unity Editor tasks using natural language.
When to skip:
- You use Unreal Engine or Godot; unity-mcp connects strictly to the Unity Editor.
- You only write gameplay C# logic outside of Unity and do not need Editor-level RPC integration.
