Add a user to a Kanboard project with the given role. Role defaults to 'project-member' if not specified. Use list_project_users to find user ids and list_projects to find project ids; to unlink a member use remove_project_user. Returns { user_id, project_id, role } on success.
Upload a file to a Kanboard task as an attachment. Provide either file_path (local file) or content_base64 (inline base64 content) — not both. project_id is resolved automatically from the task (no need to provide it). Maximum file size: 5 MB (5,242,880 bytes) — larger files return VALIDATION_ERROR before any HTTP request is made. Returns { file_id } on success.
Close (archive) an active Kanboard task. The task is set inactive and leaves the active board but is preserved — this is NOT a delete. Reversible: restore it with reopen_task. To permanently remove a task instead, use delete_task. Returns { ok: true, task_id } on success.
Add a column to a Kanboard project board. Project resolved from explicit project_id/project_identifier or .kanboard.yaml. To reorder it use move_column, to rename or change its WIP limit use update_column, to remove it use delete_column. Returns { column_id } on success.
Create a comment on a Kanboard task. The comment author is automatically set to the authenticated user (via getMe() cache); do NOT pass user_id — it is injected server-side. To edit a comment's body use update_comment; to remove one use delete_comment. Returns { comment_id } on success.
Create a new Kanboard project. Requires a name (1–255 chars). Optionally provide a description, short identifier, owner user id, start_date / end_date (ISO 8601 string or epoch seconds), and email. After creating, adjust the board with create_column / create_swimlane, add members with add_project_user, and edit attributes with update_project. Returns { project_id } on success.
Create a subtask under an existing Kanboard task. Status: 0 = todo (default), 1 = in progress, 2 = done. To list a task's subtasks use list_subtasks; to edit one use update_subtask. Returns { subtask_id, task_id } on success.
Add a swimlane to a Kanboard project. Project resolved from explicit project_id/project_identifier or .kanboard.yaml. To reorder it use move_swimlane, to rename it use update_swimlane, to remove it use delete_swimlane. Returns { swimlane_id } on success.
Create a new task in a Kanboard project. Project is resolved from explicit project_id or project_identifier, or from .kanboard.yaml. Optional fields (column_id, owner_id, category_id, swimlane_id) fall back to .kanboard.yaml defaults when not provided. To create many tasks at once use create_tasks_batch; to move the task afterward use move_task_position. Returns { task_id, project_id } on success.
Bulk-create tasks in a Kanboard project using a single JSON-RPC batch request. Accepts 1–100 tasks per call. Non-atomic: partial failure is possible — check failed[] for per-task errors. Optional fields (column_id, owner_id, category_id, swimlane_id) fall back to .kanboard.yaml defaults when not provided. Returns { created: [...], failed: [...] } — never throws on partial failure.
Permanently delete a Kanboard column from a project board. DESTRUCTIVE and irreversible — requires explicit `confirm: true`. To rename a column or change its WIP limit use update_column; to reorder it use move_column. Returns { ok: true, column_id } on success.
Permanently delete a Kanboard comment. DESTRUCTIVE and irreversible — requires explicit `confirm: true`. To edit a comment's text instead of deleting it use update_comment. Returns { ok: true, comment_id } on success.
