AI agents call list_emba_scans 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.
The 'list_' prefix conventionally denotes read-only retrieval. No description is provided, but the pattern matches sibling tools like 'get_emba_scan_status' which query existing data. Listed firmware scans are informational artifacts; accessing them has no side effects on the firmware, system, or security posture. Confidence is slightly reduced due to missing description, but the naming convention is clear.
From the tool's definition Tool name 'list_emba_scans' indicates a listing/querying operation. Description is empty, but the tool name and context (sibling tools query firmware analysis results) strongly suggest this retrieves a list of previously run EMBA scans without modification or…

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 list_emba_scans:
{
"version": "1",
"default": "deny",
"tools": {
"list_emba_scans": {}
}
}list_emba_scans is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_emba_scans. 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 list_emba_scans: 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.
list_emba_scans 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 list_emba_scans 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 list_emba_scans. 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.
list_emba_scans 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.
