Creates multiple tasks in one list. Use listId (preferred) or listName + array of tasks (each needs name). Configure batch size/concurrency via options. Tasks can have custom fields as {id, value} array and assignees as array of user IDs, emails, or usernames.
AI agents use create_bulk_tasks to create or update resources in ClickUp MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ClickUp MCP environment.
This tool creates/inserts data (tasks) into ClickUp reversibly—tasks can be edited or deleted afterward. The bulk action capability increases blast radius (multiple records created at once) compared to single-task creation, elevating severity to medium. No financial impact, no irreversible destruction, and no code execution. Categorized as Write because creation of structured data is the primary action.
From the tool's definition Tool creates multiple tasks in a list via array input; description states 'Creates multiple tasks in one list' with configurable batch size/concurrency for bulk operations.
Attacks that exploit this kind of access
Creates multiple tasks in one list. Use listId (preferred) or listName + array of tasks (each needs name). Configure batch size/concurrency via options. Tasks can have custom fields as {id, value} array and assignees as array of user IDs, emails, or usernames. It is categorised as a Write tool in the ClickUp MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the ClickUp MCP server in PolicyLayer and add a rule for create_bulk_tasks: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches ClickUp MCP. Nothing to install.
create_bulk_tasks is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_bulk_tasks rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for create_bulk_tasks. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
create_bulk_tasks is provided by the ClickUp MCP server (twofeetup/clickup-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
