What timed_capture does on Procmon
AI agents invoke timed_capture to trigger actions in Procmon. 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 timed_capture is rated High
The tool's core capability to launch shell commands at the start of a timed capture session makes this an Execute-class tool. While snapshot capture itself is observational (Read), the optional shell command execution component elevates it to Execute.
From the tool's definition Tool description states 'with optional shell trigger command launched at start' — this explicitly indicates execution of arbitrary shell commands.
Attacks that exploit this kind of access
The rule that runs timed_capture safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Procmon, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For timed_capture, this is the rule to start with:
timed_capture 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 Procmon, apply this rule, and every timed_capture call is checked against it from then on.
Questions about timed_capture
Repeated snapshots over a duration with optional shell trigger command launched at start. It is categorised as a Execute tool in the Procmon MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Procmon MCP server in PolicyLayer and add a rule for timed_capture: 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.
timed_capture 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 timed_capture 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 timed_capture. 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.
timed_capture 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.
