add_queue_item · UiPath MCP Server MCP: Risk & Policy

WHAT IT DOES

What add_queue_item does on UiPath MCP Server

AI agents use add_queue_item to create or update resources in UiPath MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your UiPath MCP Server environment.

WHY IT NEEDS A POLICY

Why add_queue_item needs a policy

Adding a queue item is a write operation that creates new data within UiPath Orchestrator. While it modifies state, it is reversible and does not rise to Execute (no code execution) or Destructive (no permanent deletion).

From the tool's definition Tool description states 'Add a new queue item to the given UiPath queue' — this creates new data in a queue system. The action is reversible (queue items can be removed), and does not execute arbitrary code or permanently destroy data.

Verdict

add_queue_item Rate-limited

add_queue_item stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

What risk level is add_queue_item? +

add_queue_item is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit add_queue_item? +

Yes. Add a rate_limit block to the add_queue_item 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.

How do I block add_queue_item completely? +

Set action: deny in the PolicyLayer policy for add_queue_item. 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.

What MCP server provides add_queue_item? +
