What is mcp-click-up?

A ClickUp connector that chooses between the cupt command-line tool and ClickUp's official MCP connector for different task-management operations.

It is for creating and updating ClickUp tasks, managing documents and goals, handling bulk operations, and reading Markdown descriptions correctly.

It prevents Markdown from being stored incorrectly as plain text in ClickUp descriptions and routes routine, document, goal, and bulk work to the appropriate interface.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00034	$0.06109
Opus 5	$0.00017	$0.03054
Sonnet 5	$0.00007	$0.01222
Haiku 4.5	$0.00003	$0.00611

Security

Grade A, and why

mcp-click-up scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

The scan reads SKILL.md. This mod also ships 2 executable files (examples/task-queue-workflow.sh, examples/time-tracking-workflow.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 493 lines — stays where its author put it; the contents beside it link to each section on GitHub.

mcp-click-up Skill

ClickUp task management via cupt CLI (primary) and official ClickUp MCP (secondary). Operation-based routing: cupt handles daily task ops, MCP handles documents, goals, and bulk operations.

MARKDOWN FORMATTING CONTRACT — READ BEFORE ANY CLICKUP WRITE

ClickUp stores the plain description field literally. Markdown submitted there shows up in the ClickUp UI as raw ### Heading, **bold**, and - [ ] text. Whenever the content contains ANY markdown syntax, use the markdown-aware parameter for the operation:

Operation	Required parameter
Task create	`markdown_description`
Task update (raw v2 API / Code Mode server)	`markdown_content` (`markdown_description` also accepted)
Task update (claude.ai ClickUp connector)	`markdown_description`
Document or page create	`content` plus `content_format: "markdown"` (connector pages: `"text/md"`)
Task read-back	`include_markdown_description=true`

This contract applies identically on every surface: Code Mode (clickup_official.clickup_official_*), the claude.ai ClickUp connector (clickup_create_task and friends), and the raw ClickUp v2 REST API. Live-verified 2026-07-15 (scratch-task round trips plus a full Product Owner task export, all rendering headings, bold, dividers, and checkboxes correctly).

Push shape for a markdown artifact: the document's H1 becomes the task name (drop it from the body); strip internal HTML comments and processing metadata; everything else travels verbatim.

Failure symptom: literal ### or ** visible in a ClickUp task means someone used the plain description field. That is the defect, not a rendering bug.

Worked examples: references/mcp-tools.md (Markdown Transport Contract + invocation patterns).

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
