What enqueue_task does on State Trace

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

Why enqueue_task needs a policy

This tool creates a new task entry in an existing run's queue. It modifies the state of the system by adding a task (a reversible write operation), but does not execute code, delete data, or involve financial transactions. Misuse could cause unintended task scheduling or resource consumption, warranting medium severity.

From the tool's definition Enqueue a task onto an existing run. Supports dependencies, priority, maxAttempts, retry policy, and an optional per-attempt timeoutMs wall-clock budget.

Questions about enqueue_task

What does the enqueue_task tool do? +

Enqueue a task onto an existing run. Supports dependencies, priority, maxAttempts, retry policy, and an optional per-attempt timeoutMs wall-clock budget. It is categorised as a Write tool in the State Trace MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on enqueue_task? +

Register the State Trace MCP server in PolicyLayer and add a rule for enqueue_task: 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 State Trace. Nothing to install.

What risk level is enqueue_task? +

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

Can I rate-limit enqueue_task? +

Yes. Add a rate_limit block to the enqueue_task 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 enqueue_task completely? +

Set action: deny in the PolicyLayer policy for enqueue_task. 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 enqueue_task? +

enqueue_task is provided by the State Trace MCP server (agent-pattern-labs/state-trace). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
