unity-mcp-plugin vs fastmcp
unity-mcp-plugin: This package runs a lightweight HTTP bridge inside the Unity Editor on localhost:7890. The companion Unity MCP Server connects to it, exposing 288 tools to AI assistants across 30+ feature categories. It enables AI to control the Unity Editor for game development tasks like scene creation, scripting, building, and profiling.; fastmcp: FastMCP is a standard framework for building Model Context Protocol (MCP) applications, which connect LLMs to tools and data. It simplifies the process by automatically generating schemas, validation, and documentation for tools, and managing transport negotiation and authentication for server connections. FastMCP offers a comprehensive solution for developing, deploying, and scaling MCP-powered systems.
