clickup-mcp

Lightweight ClickUp MCP server focused on task management. 39 tools with token-optimized responses - API responses automatically slimmed from thousands of characters to essentials.

Why This Server?

ClickUp's API returns extremely verbose JSON. This server strips it down:

Less tokens = faster responses, lower costs, more context for your AI.

Response Slimming

All responses are automatically trimmed to save tokens. The ClickUp API returns extremely verbose JSON - this server strips it down to what matters.

clickup_whoami - from ~3,500 chars to ~160:

// Before (ClickUp API raw)
{"user":{"id":12345678,"username":"Jane Doe","email":"jane@example.com","color":"#0388d1",
"profilePicture":"https://attachments.clickup.com/...","initials":"JD",

"date_invited":"..."},"invited_by":{"id":22222222,...},

Multi-List Membership (2)

These do not move a task. The ClickUp v2 API has no move-between-lists endpoint. Verified against the live API 2026-08-12: POST /list/{list}/task/{task} adds a secondary location and leaves the home list unchanged, while a list_id in PUT /task/{id} returns HTTP 200 and is silently ignored. To genuinely move a task and keep its custom ID and history, use the ClickUp web UI (right-click -> Move). Multi-list membership also requires the paid Tasks-in-Multiple-Lists feature.

Workspace Members (2)

• clickup_get_workspace_members - All workspace members

• clickup_get_list_members - List-specific members
