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 4.7This 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": {
