Sleeps for a specified amount of time (in milliseconds). Args: sleep_milliseconds: Number of milliseconds to sleep for
AI agents call sleep as a supporting operation in OBS MCP Server workflows.
This tool simply pauses execution for a given duration. It does not read, write, execute, destroy, or move money. It is a timing/delay utility with minimal blast radius — the worst misuse is introducing unnecessary delays.
From the tool's definition 'Sleeps for a specified amount of time (in milliseconds)'
Documented attack patterns abuse exactly the kind of access sleep gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OBS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for sleep:
{
"version": "1",
"default": "deny",
"tools": {
"sleep": {
"limits": [
{
"counter": "sleep_rate",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
}
}sleep gets a rate cap, and everything else on the server is denied unless you say otherwise.

Sleeps for a specified amount of time (in milliseconds). Args: sleep_milliseconds: Number of milliseconds to sleep for. It is categorised as a Other tool in the OBS MCP Server MCP Server, which means it performs auxiliary operations.
Register the OBS MCP Server MCP server in PolicyLayer and add a rule for sleep: 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 OBS MCP Server. Nothing to install.
sleep is a Other tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the sleep 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 sleep. 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.
sleep is provided by the OBS MCP Server MCP server (royshil/obs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
