Show HN: Godot MCP – Give AI assistants full access to the Godot editor

Hi HN, I built an open-source MCP server + Godot editor plugin that gives AI assistants (Claude, Cursor, etc.) direct access to the running Godot editor. The problem: AI coding assistants can edit scripts, but they're blind to the Godot editor. They can't see your scene tree, add nodes, check for errors, or understand your project structure. You end up copy-pasting context back and forth. The solution: A Godot plugin connects to an MCP server via WebSocket. The AI gets 32 tools that execute inside the live editor - scene manipulation, script editing with validation, project search, console error reading, node property discovery, and more. How it works: Install the MCP server: npx -y godot-mcp-server Copy the plugin into your Godot project Enable it, and your AI assistant can now talk directly to the editor What makes this different from other Godot AI tools: Tools run inside the actual editor, not by parsing files from disk. When the AI adds a node, it appears in the editor immediately. When it reads errors, it gets real editor diagnostics, not regex guesses. Built with TypeScript (MCP server) and GDScript (plugin).
