AI agents call await_output to retrieve information from Interactive Automation MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite empty description, the name 'await_output' and context of terminal automation indicates this passively reads/retrieves program output. It has no side effects—it observes rather than modifies, executes, or deletes. Confidence is moderate-high due to missing description but strong naming semantics and server context.
From the tool's definition Tool name 'await_output' combined with sibling tools like 'get_screen_content' and 'send_input' suggests this reads or waits for terminal/program output without modifying state.
Documented attack patterns abuse exactly the kind of access await_output gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Interactive Automation MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for await_output:
{
"version": "1",
"default": "deny",
"tools": {
"await_output": {}
}
}await_output is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

await_output. It is categorised as a Read tool in the Interactive Automation MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Interactive Automation MCP Server MCP server in PolicyLayer and add a rule for await_output: 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 Interactive Automation MCP Server. Nothing to install.
await_output 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 await_output 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 await_output. 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.
await_output is provided by the Interactive Automation MCP Server MCP server (wehnsdaefflae/terminal-control-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Interactive Automation MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
