Ask the human operator a question and wait for their response. Use this when you need human input, decision-making, or information that only a human would know.
AI agents call ask_human to retrieve information from Human-Controlled MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a human for information and waits for a response — it retrieves data (human input) without creating, modifying, or deleting anything. The primary action is requesting and receiving information, which maps to Read.
From the tool's definition "Ask the human operator a question and wait for their response" and "need human input, decision-making, or information that only a human would know"
Attacks that exploit this kind of access
Ask the human operator a question and wait for their response. Use this when you need human input, decision-making, or information that only a human would know. It is categorised as a Read tool in the Human-Controlled MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Human-Controlled MCP Server MCP server in PolicyLayer and add a rule for ask_human: 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 Human-Controlled MCP Server. Nothing to install.
ask_human 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 ask_human 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 ask_human. 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.
ask_human is provided by the Human-Controlled MCP Server MCP server (lardratboy/human_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
