Close an active debug session and stop any attached pwncli driver.
AI agents use close_debug_session to create or update resources in Pwno — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pwno environment.
An AI agent can call close_debug_session faster than any human can review — one bad instruction and it creates or modifies resources in Pwno by the hundred, each call as confident as the last.
Documented attack patterns abuse exactly the kind of access close_debug_session gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Pwno, and nothing reaches the server without passing your rules. This is the rule we recommend for close_debug_session:
{
"version": "1",
"default": "deny",
"tools": {
"close_debug_session": {
"limits": [
{
"counter": "close_debug_session_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}close_debug_session stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Close an active debug session and stop any attached pwncli driver. It is categorised as a Write tool in the Pwno MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Pwno MCP server in PolicyLayer and add a rule for close_debug_session: 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 Pwno. Nothing to install.
close_debug_session is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the close_debug_session 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 close_debug_session. 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.
close_debug_session is provided by the Pwno MCP server (pwno-io/pwno-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
