Tools

Tool	Description
`list_projects`	List all projects in your workspace
`get_project`	Get details of a specific project
`list_tasks`	List tasks in a project — paginated (6 per page by default, up to 50), with `search` (matches title, description, and the human-readable ID like `EL-90`), `statusIds`/`assigneeIds` filters, and `sortBy`/`sortOrder`
`get_task`	Get details of a specific task by its internal ID
`get_task_by_external_id`	Get a task by its human-readable ID (e.g. `EL-90`), without needing the internal task ID or paging through `list_tasks`
`create_task`	Create a task (title, description, assignees, status, priority, labels, due date, cycle). Pass `parentTaskId` to create it directly as a subtask
`update_task`	Update an existing task. Pass `parentTaskId` to nest it under another task, or `null` to detach it from its current parent
`list_subtasks`	List the subtasks of a given task
`list_comments`	List comments on a task
`add_comment`	Add a comment to a task
`list_members`	List all members of the workspace
`list_statuses`	List a project’s task statuses — each project has its own set, statuses aren’t shared workspace-wide
`list_labels`	List labels available for a project (workspace-wide labels plus labels scoped to that project)

Notes

Task descriptions and comments are plain text — elean converts them to its internal rich text format automatically.
create_task and update_task accept up to 5 assignee IDs. On update_task, assigneeIds and labelIds replace the existing list rather than merging into it.
priority is one of low, medium, high, or urgent — custom priorities aren’t exposed over MCP.
statusId and labelIds take IDs, not names — use list_statuses and list_labels to look them up for a project first.
list_tasks is paginated; prefer get_task_by_external_id or list_tasks with search over paging through everything when you already know which task you’re after.
Subtasks only support one level of nesting — the task you nest under (parentTaskId) can’t itself already be a subtask.
