Wait for the specified number of seconds. Args: seconds (int, optional): Number of seconds to wait. Defaults to 3. Returns: str: A message confirming the wait
AI agents invoke wait to trigger actions in Mcp Browser Use. 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.
The wait function executes code (a timer/sleep operation) and could be chained with other browser actions to create timed sequences or timing-based attacks. However, severity is low because the operation has no direct side effects on data or external systems—it merely introduces delays.
From the tool's definition Tool executes a wait/sleep operation with a specified duration. While the operation itself is benign (merely introduces a delay), the ability to execute arbitrary control flow operations that modify timing behavior constitutes execution capability.
Documented attack patterns abuse exactly the kind of access wait gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Browser Use, and nothing reaches the server without passing your rules. This is the rule we recommend for wait:
{
"version": "1",
"default": "deny",
"tools": {
"wait": {
"limits": [
{
"counter": "wait_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
} 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.

Wait for the specified number of seconds. Args: seconds (int, optional): Number of seconds to wait. Defaults to 3. Returns: str: A message confirming the wait. It is categorised as a Execute tool in the Mcp Browser Use MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Mcp Browser Use MCP server in PolicyLayer and add a rule for 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 Mcp Browser Use. Nothing to install.
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 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 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.
wait is provided by the Mcp Browser Use MCP server (vinayak-mehta/mcp-browser-use). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
