Gets complete workspace hierarchy (spaces, folders, lists). Returns tree structure with names and IDs for navigation. Resets all caches - useful after making changes or if not picking up expected results.
AI agents call get_workspace_hierarchy to retrieve information from ClickUp MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries and returns organizational structure data. While it has a side effect (cache reset), this is a housekeeping operation that doesn't alter data or trigger external actions. The primary function is information retrieval, making this a Read classification with low severity—useful for navigation but minimal risk of harmful misuse.
From the tool's definition Tool description states it 'Gets complete workspace hierarchy (spaces, folders, lists)' and 'Returns tree structure with names and IDs for navigation.' These are pure retrieval operations with no modification, deletion, or execution of external code.

Gets complete workspace hierarchy (spaces, folders, lists). Returns tree structure with names and IDs for navigation. Resets all caches - useful after making changes or if not picking up expected results. It is categorised as a Read tool in the ClickUp MCP MCP Server, which means it retrieves data without modifying state.
Register the ClickUp MCP server in PolicyLayer and add a rule for get_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. Nothing to install.
get_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 get_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 get_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.
get_workspace_hierarchy 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.
