WHAT IT DOES

What scan_bios does on Mcp Control Plane

AI agents call scan_bios to retrieve information from Mcp Control Plane without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why scan_bios is rated Low

The tool performs file system enumeration/listing of BIOS files in a specific directory. This is a read-only information retrieval operation. While BIOS files could theoretically be sensitive, the tool itself does not execute code, modify files, or cause destructive changes. The context of 'without validating copyrighted contents' suggests it simply lists directory contents.

From the tool's definition Tool description states 'List BIOS files' — a query operation with no side effects. The phrase 'without validating copyrighted contents' indicates passive enumeration rather than modification or execution.

RECOMMENDED RULE

The rule that runs scan_bios safely

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

scan_bios Allowed

scan_bios is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "scan_bios": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Control Plane, apply this rule, and every scan_bios call is checked against it from then on.

How do I enforce a policy on scan_bios? +

Register the Mcp Control Plane MCP server in PolicyLayer and add a rule for scan_bios: 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 Mcp Control Plane. Nothing to install.

What risk level is scan_bios? +

Can I rate-limit scan_bios? +

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

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

scan_bios is provided by the Mcp Control Plane MCP server (albertik322-sudo/mcp-control-plane). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
