AI agents call get_kernel_info to retrieve information from EMBA-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
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…
Documented attack patterns abuse exactly the kind of access get_kernel_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and EMBA-MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_kernel_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_kernel_info": {}
}
}get_kernel_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_kernel_info. It is categorised as a Read tool in the EMBA-MCP MCP Server, which means it retrieves data without modifying state.
Register the EMBA- MCP server in PolicyLayer and add a rule for get_kernel_info: 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.
get_kernel_info is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_kernel_info 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.
Set action: deny in the PolicyLayer policy for get_kernel_info. 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.
get_kernel_info 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.
Start from EMBA-MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
