Get list of detected ISM band devices (weather stations, sensors, etc.)
AI agents call ism_get_devices to retrieve information from AetherLink SDR MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation by listing detected ISM band devices. It has no side effects, does not execute commands or control hardware, and does not modify any state. The passive nature of device detection and enumeration places it squarely in the Read category.
From the tool's definition Tool name 'ism_get_devices' and description 'Get list of detected ISM band devices' indicate a passive query operation that retrieves information about detected devices without modifying, executing, or controlling anything.
Documented attack patterns abuse exactly the kind of access ism_get_devices gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AetherLink SDR MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for ism_get_devices:
{
"version": "1",
"default": "deny",
"tools": {
"ism_get_devices": {}
}
}ism_get_devices is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get list of detected ISM band devices (weather stations, sensors, etc.). It is categorised as a Read tool in the AetherLink SDR MCP MCP Server, which means it retrieves data without modifying state.
Register the AetherLink SDR MCP server in PolicyLayer and add a rule for ism_get_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 AetherLink SDR MCP. Nothing to install.
ism_get_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 ism_get_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 ism_get_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.
ism_get_devices is provided by the AetherLink SDR MCP server (n-erickson/aetherlink-sdr-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from AetherLink SDR MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
