Clickup MCP server

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.
