Identify the user and their environment. Returns email, local timezone of this MCP process, the Maito instance URL, and number of workspaces. Call first when you need user context.

List all workspaces. Each workspace is an isolated container — spaces/boards/cards/notes do not cross workspace boundaries. Call this first to orient yourself.

List spaces. If workspaceId is omitted and there is exactly one workspace, uses it; otherwise returns spaces from all workspaces labelled with workspaceId.

List boards. Filter by workspaceId and/or spaceId. Each board includes workspaceId + spaceId.

List columns (statuses) of a board, ordered left-to-right. Use before create_card / update_card to pick the right column by name.

List tags. Tags are scoped to a space. Filter by spaceId or workspaceId. Use to resolve tagIds to human-readable names.

List cards (summaries). Filter by workspaceId, boardId, done, archived, priorityOnly. Each card includes workspaceId + boardId + columnId.

Return a single card with full details: description, resolved tag names, journal entries, subtasks, plus board/column/workspace context.

Full-text search across card titles and descriptions. Optionally scope to workspaceId / boardId.

Create a task card. Either columnId (precise) or boardId (uses first column). Workspace inherited from column/board.

Update card fields. patch.columnId MOVES the card to another column (mark Done by moving, or pass done:true). Omit fields you do not want to change.

Archive a card (soft-delete — recoverable from Archive view).

Add a comment / journal entry to a card. Use for status updates, notes, decisions.

Create a new space (top-level container) within a workspace.

Create a new board inside a space. Spawns 3 default columns: Todo / In Progress / Done.

Create a new column (status) in a board.

Search notes by title and body. Optionally scope to workspace.

Get full body of a note by id.

Create a new note. workspaceId required when multiple workspaces exist.

Return cards scheduled for today in the local timezone of this MCP process. Pass dayOffset=1 for tomorrow, -1 for yesterday. Filter by workspaceId.

Activity feed: card_created, card_done, card_moved, board_created, space_created, note_created, etc. Answers "what did I do recently".
