WHAT IT DOES

What stop_smb_process does on Pentester-MCP

AI agents invoke stop_smb_process to trigger actions in Pentester-MCP. 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.

RISK

Why stop_smb_process is rated High

This tool executes a command to kill a running process. While it does not create, modify, or delete persistent data (ruling out Write/Destructive), it actively controls system state by terminating a subprocess. The effect is immediate and depends on the process identifier or state argument provided.

From the tool's definition Terminates a background impacket-smbclient process — directly stops an active system process, which is an execution action that triggers external operations whose effects depend on which process is terminated.

RECOMMENDED RULE

The rule that runs stop_smb_process safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Pentester-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For stop_smb_process, this is the rule to start with:

stop_smb_process Rate-limited

stop_smb_process 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.

FAQ

Questions about stop_smb_process

What does the stop_smb_process tool do? +

Terminates a background impacket-smbclient process. It is categorised as a Execute tool in the Pentester-MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on stop_smb_process? +

Register the Pentester MCP server in PolicyLayer and add a rule for stop_smb_process: 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 Pentester-MCP. Nothing to install.

What risk level is stop_smb_process? +

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

Can I rate-limit stop_smb_process? +

Yes. Add a rate_limit block to the stop_smb_process 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 stop_smb_process completely? +

Set action: deny in the PolicyLayer policy for stop_smb_process. 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 stop_smb_process? +

stop_smb_process is provided by the Pentester MCP server (halilkirazkaya/pentester-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
