Point-in-time snapshot of matching processes: processes, modules, network connections.
AI agents call capture_snapshot to retrieve information from Procmon without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool captures and returns information about running processes, loaded modules, and active network connections without altering system state. 'Snapshot' denotes a retrieval operation. While the blast radius is medium (detailed internal system visibility could inform attacks), the action itself is purely observational with no side effects, clearly placing it in the Read category.
From the tool's definition Tool description states 'Point-in-time snapshot of matching processes: processes, modules, network connections' - a read-only operation that retrieves system state without modification.
Documented attack patterns abuse exactly the kind of access capture_snapshot gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Procmon, and nothing reaches the server without passing your rules. This is the rule we recommend for capture_snapshot:
{
"version": "1",
"default": "deny",
"tools": {
"capture_snapshot": {}
}
}capture_snapshot is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Point-in-time snapshot of matching processes: processes, modules, network connections. It is categorised as a Read tool in the Procmon MCP Server, which means it retrieves data without modifying state.
Register the Procmon MCP server in PolicyLayer and add a rule for capture_snapshot: 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 Procmon. Nothing to install.
capture_snapshot 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 capture_snapshot 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 capture_snapshot. 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.
capture_snapshot is provided by the Procmon MCP server (0xhackerfren/procmon-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
