Godot Documentation MCP Server

A Model Context Protocol (MCP) server that provides queryable access to Godot Engine documentation.

Features

• Full-text search across 1066+ Godot classes using SQLite FTS5

• 8 powerful tools for querying classes, methods, properties, signals, and inheritance

• Fast queries with indexed database (~50-100MB)

• Zero deployment dependencies - single SQLite file

Installation

cd C:\GodotProjects\godot-docs-mcp
pip install -e .

Build Documentation Database

git -C C:\GodotProjects\godot-docs switch stable
git -C C:\GodotProjects\godot-docs pull --ff-only
python scripts/build_index.py C:\GodotProjects\godot-docs --version 4.7

This will parse the Godot 4.7 stable RST files and create src/data/godot_docs.db, which is the database loaded by the MCP server.

Usage with OpenCode

Add to your OpenCode configuration:

{
  "mcpServers": {
    "godot-docs": {
      "command": "python",
      "args": ["-m", "src.server"],
      "cwd": "C:\\GodotProjects\\godot-docs-mcp"
    }
  }
}

Available Tools

1. search_class - Search for classes by name or description

2. get_class_docs - Get full documentation for a class

3. get_method_docs - Get documentation for a specific method

4. search_methods - Search methods across all classes

5. list_class_members - List all members of a class

6. get_inheritance_tree - Get inheritance hierarchy

7. search_by_return_type - Find methods by return type

8. search_guides - Search tutorial documentation

Example Queries

# Search for Node class
search_class(query="Node")

# Get all methods of Control class
list_class_members(class_name="Control", member_type="methods")

# Find methods that return Vector2
search_by_return_type(return_type="Vector2")

# Get inheritance tree for CanvasItem
get_inheritance_tree(class_name="CanvasItem", direction="both")

Architecture

• Database: SQLite with FTS5 full-text search

• Parser: Regex-based RST parser for Godot class documentation

• Server: Python MCP server using official SDK

• Schema: Normalized tables for classes, methods, properties, signals, enums
