WHAT IT DOES

What host does on OpenClaw

AI agents call host as a supporting operation in OpenClaw workflows.

RISK

Why host is rated Low

The description lists nouns (sandbox, gateway, node) without indicating what the tool does. It could read, write, execute, or configure network/host settings. With no actionable information, classification defaults to Other with very low confidence.

From the tool's definition Tool description is 'sandbox, gateway, or node' — extremely vague and uninformative; no clear action or side effect can be determined from name or description alone.

RECOMMENDED RULE

The rule that runs host safely

PolicyLayer is an MCP gateway: it sits between your AI agents and OpenClaw, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For host, this is the rule to start with:

host Rate-limited

host gets a rate cap, and everything else on the server is denied unless you say otherwise.

FAQ

Questions about host

What does the host tool do? +

sandbox, gateway, or node. It is categorised as a Other tool in the OpenClaw MCP Server, which means it performs auxiliary operations.

How do I enforce a policy on host? +

Register the OpenClaw MCP server in PolicyLayer and add a rule for host: 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 OpenClaw. Nothing to install.

What risk level is host? +

host is a Other tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit host? +

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

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