create_debug_session

THE RISK

High Risk

Creating a debug session initializes an external process (GDB/pwndbg) and establishes a stateful runtime environment. This goes beyond a simple write operation as it triggers external execution infrastructure. Misuse could allow an agent to begin debugging arbitrary binaries or processes, though the session creation itself is a prerequisite step rather than directly executing exploits.

From the tool's definition 'Create or return a debug session' combined with server description 'stateful debugging and binary research system integrating GDB + pwndbg'

Documented attack patterns abuse exactly the kind of access create_debug_session gives an agent:

HOW TO CONTROL CREATE_DEBUG_SESSION

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 create_debug_session:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_debug_session": {
      "limits": [
        {
          "counter": "create_debug_session_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

create_debug_session 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.

Create a free account and register Pwno — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

What does the create_debug_session tool do? +

Create or return a debug session by id. It is categorised as a Execute tool in the Pwno MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on create_debug_session? +

Register the Pwno MCP server in PolicyLayer and add a rule for create_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.

What risk level is create_debug_session? +

create_debug_session is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit create_debug_session? +

Yes. Add a rate_limit block to the create_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.

How do I block create_debug_session completely? +

Set action: deny in the PolicyLayer policy for create_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.

What MCP server provides create_debug_session? +

create_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.

Enforce policy on every Pwno tool call.
