Godot MCP Documentation Server

A Model Context Protocol (MCP) server that provides AI assistants with access to the complete Godot Engine documentation, helping developers with Godot development by serving documentation directly to LLMs.

Purpose

This server bridges the gap between AI assistants and Godot documentation, allowing developers to get instant, accurate answers about Godot classes, tutorials, and features without leaving their AI chat interface.

Deployment

1. Clone the repository:

   git clone https://github.com/Nihilantropy/godot-mcp-docs.git
   cd godot-mcp-docs

2. Build the Docker image:

   docker build -f deploy/Dockerfile -t godot-mcp-docs:local .

3. Configure your MCP client (Claude Desktop example):

   {
     "mcpServers": {
       "godot-mcp-docs": {
         "command": "docker",
         "args": [
           "run",
           "--rm",
           "-i",
           "godot-mcp-docs:local"
         ]
       }
     }
   }

Recommended System Prompt

For optimal results when working with Godot, use this system prompt:

"When working with Godot game development questions, always search for the latest available documentation using the godot-mcp-docs tools. Start with get_documentation_tree() to understand the documentation structure, then use get_documentation_file() to retrieve specific information about classes, tutorials, or features. Prioritize official Godot documentation over general knowledge when providing Godot-related assistance."
