WHAT IT DOES

What get_kernel_info does on EMBA-MCP

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

RISK

Why get_kernel_info is rated Low

This tool retrieves kernel information from EMBA firmware analysis results. The 'get_' prefix indicates a read-only query operation. While the description is empty, the naming convention and context of sibling tools on the same EMBA analysis server—which query security findings, protection mechanisms, and system details—strongly suggests this retrieves kernel details for analysis purposes without side effects or…

From the tool's definition Tool name 'get_kernel_info' with 'get_' prefix and 'info' suffix, following the pattern of sibling tools like 'get_binary_protection_mechanisms', 'get_bootloader_info', 'get_credentials_and_secrets', and 'get_filesystem_overview' which all retrieve firmware…

RECOMMENDED RULE

The rule that runs get_kernel_info 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 get_kernel_info, this is the rule to start with:

get_kernel_info Allowed

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

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

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

The button opens the PolicyLayer dashboard: create your workspace, connect EMBA-MCP, apply this rule, and every get_kernel_info call is checked against it from then on.
