Get tasks from a list with optional filtering
AI agents call list_tasks to retrieve information from ClickUp MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries task data from ClickUp lists with optional filtering capabilities. There are no side effects, data modifications, deletions, or external operations triggered. It falls squarely into the Read category as a data retrieval operation. Severity is low because unauthorized access to task lists, while a privacy concern, does not enable direct harm, destruction of data, or financial impact.
From the tool's definition Tool name 'list_tasks' and description 'Get tasks from a list with optional filtering' indicate data retrieval without modification. The verb 'Get' and action of filtering existing tasks confirms read-only behavior.
Attacks that exploit this kind of access
Get tasks from a list with optional filtering. It is categorised as a Read tool in the ClickUp MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ClickUp MCP Server MCP server in PolicyLayer and add a rule for list_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 Server. Nothing to install.
list_tasks is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_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 list_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.
list_tasks is provided by the ClickUp MCP Server MCP server (yihaowang/clickup-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
