List complete hierarchy of the ClickUp workspace
AI agents call workspace_hierarchy 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 queries and returns organizational structure information from the ClickUp workspace without modifying, deleting, or executing operations. It is a read-only retrieval operation, making it the lowest-severity category. The low severity reflects that exposing workspace hierarchy has minimal blast radius—it reveals structural organization but cannot directly harm data or operations.
From the tool's definition Tool name is 'workspace_hierarchy' and description states 'List complete hierarchy of the ClickUp workspace'. The verb 'list' and action of retrieving workspace structure indicate data retrieval with no side effects.
Attacks that exploit this kind of access
List complete hierarchy of the ClickUp workspace. 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 workspace_hierarchy: 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.
workspace_hierarchy 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 workspace_hierarchy 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 workspace_hierarchy. 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.
workspace_hierarchy is provided by the ClickUp MCP Server MCP server (mcpflow/taazkareem_clickup-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
