AI agents invoke wait-task to trigger processes or run actions in Mcp Codex Worker. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
wait-task can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access wait-task gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Block until a task settles or asks for input. Returns as soon as the task reaches a terminal state (completed, failed, cancelled) or enters input_required. If timeout_ms elapses first, it returns the current status. PATTERN: loop wait-task → if input_required, call respond-task → loop back. Give each call enough time to catch meaningful progress.. It is categorised as a Execute tool in the Mcp Codex Worker MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Mcp Codex Worker MCP server in PolicyLayer and add a rule for wait-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 Mcp Codex Worker. Nothing to install.
wait-task is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the wait-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.
Set action: deny in the PolicyLayer policy for wait-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.
wait-task is provided by the Mcp Codex Worker MCP server (mcp-codex-worker). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
