WHAT IT DOES

What stop_emba_scan does on EMBA-MCP

AI agents invoke stop_emba_scan to trigger actions in EMBA-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_emba_scan is rated High

Stopping an active scan is an Execute action that triggers an external operation (halting the EMBA firmware analysis engine). While not destructive of data or financial in nature, it interrupts a system operation whose continuation state depends on the tool's invocation. This could disrupt analysis workflows and has blast radius potential if invoked by an AI agent without user intent.

From the tool's definition Tool name 'stop_emba_scan' indicates termination of an active firmware analysis scan process.

RECOMMENDED RULE

The rule that runs stop_emba_scan safely

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

stop_emba_scan Rate-limited

stop_emba_scan 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.

How do I enforce a policy on stop_emba_scan? +

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

What risk level is stop_emba_scan? +

How do I block stop_emba_scan completely? +

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

stop_emba_scan is provided by the EMBA MCP server (0xbuz3r/emba-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
