List MindMup files from Google Drive (folders and non-.mup filtered by default). Returns id, name, folder_url, size, modified_time.
read_mindmap
Read a MindMup file by file_id or file_name (one required; name uses first partial match). Small files return content_type: 'full'. Large files return content_type: 'outline_only' with tree_outline, section_stats, and suggested_start_paths.
search_mindmap
Search nodes by keyword. Params: file_id, keyword, optional node_path (subtree scope), max_results=30, normalize_whitespace=True. Returns nodes with node_path, title_preview, breadcrumb, children_count.
get_mindmap_section
Drill into a section by node_path (dotted integers, root is '1', e.g. '1.2.3'). Optional max_depth, offset=0, limit=0. Returns content_type: 'full' | 'outline_only' | 'paginated' | 'truncated' — auto-switches when the section is still too large.
