AI agents call list_bluetooth_devices to retrieve information from SeldomMaster without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs discovery/enumeration of local network resources (Bluetooth devices) without executing code, modifying state, or deleting data. It is therefore a Read operation. Severity is elevated to medium because enumeration of local wireless devices could reveal sensitive infrastructure, personal devices, or network topology in a restricted environment, enabling downstream attacks.
From the tool's definition Tool name 'list_bluetooth_devices' and description 'Discovers locally visible Bluetooth devices' indicate passive enumeration of nearby Bluetooth peripherals without modification or execution.
Documented attack patterns abuse exactly the kind of access list_bluetooth_devices gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SeldomMaster, and nothing reaches the server without passing your rules. This is the rule we recommend for list_bluetooth_devices:
{
"version": "1",
"default": "deny",
"tools": {
"list_bluetooth_devices": {}
}
}list_bluetooth_devices is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Discovers locally visible Bluetooth devices. It is categorised as a Read tool in the SeldomMaster MCP Server, which means it retrieves data without modifying state.
Register the SeldomMaster MCP server in PolicyLayer and add a rule for list_bluetooth_devices: 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 SeldomMaster. Nothing to install.
list_bluetooth_devices 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_bluetooth_devices 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_bluetooth_devices. 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_bluetooth_devices is provided by the SeldomMaster MCP server (paralax/seldommonster). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SeldomMaster, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
