clickup-mcp

Lightweight ClickUp MCP server focused on task management. 37 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.
