What events_wait does on OpenClaw
AI agents invoke events_wait to trigger actions in OpenClaw. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why events_wait is rated High
This tool performs a blocking wait/poll on an external event queue, which constitutes triggering an external operation rather than a simple passive read. It interacts with a live event system and its effects depend on what events are queued. Severity is medium because misuse could stall agent workflows or cause unintended event consumption, though it does not directly destroy data or move money.
From the tool's definition 'Wait for the next queued OpenClaw conversation event' — blocking wait/poll operation that triggers external system interaction
Attacks that exploit this kind of access
The rule that runs events_wait 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 events_wait, this is the rule to start with:
events_wait stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect OpenClaw, apply this rule, and every events_wait call is checked against it from then on.
Questions about events_wait
Wait for the next queued OpenClaw conversation event. It is categorised as a Execute tool in the OpenClaw MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the OpenClaw MCP server in PolicyLayer and add a rule for events_wait: 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.
events_wait 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 events_wait 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 events_wait. 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.
events_wait is provided by the OpenClaw MCP server (openclaw). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
