Resolves an array of assignee names or emails to ClickUp user IDs. Returns an array of user IDs, or errors for any that cannot be resolved.
AI agents call resolve_assignees 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.
This tool only looks up and returns user IDs based on names or emails — a pure read/query operation with no side effects on any data. It cannot modify, create, or delete anything.
From the tool's definition 'Resolves an array of assignee names or emails to ClickUp user IDs. Returns an array of user IDs, or errors for any that cannot be resolved.'
Attacks that exploit this kind of access
Resolves an array of assignee names or emails to ClickUp user IDs. Returns an array of user IDs, or errors for any that cannot be resolved. 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 resolve_assignees: 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.
resolve_assignees 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 resolve_assignees 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 resolve_assignees. 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.
resolve_assignees 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.
