Implementation Reference
- MCP tool handler and registration for 'get_node_types'. This decorated function defines the tool's input (language: str) and output (Dict[str, str]), and delegates execution to describe_node_types.@mcp_server.tool() def get_node_types(language: str) -> Dict[str, str]: """Get descriptions of common node types for a language.
