AI agents call sdr_get_status 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 queries and returns information about the current state and settings of the Software Defined Radio without performing any actions, executing code, or modifying system state. It is a passive information retrieval operation, fitting squarely into the Read category with minimal risk even if called inappropriately by an AI agent.
From the tool's definition Tool name 'sdr_get_status' and description 'Get current SDR status and configuration' indicate a retrieval operation with no modification or execution of commands.
Documented attack patterns abuse exactly the kind of access sdr_get_status 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 sdr_get_status:
{
"version": "1",
"default": "deny",
"tools": {
"sdr_get_status": {}
}
}sdr_get_status 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.
Get current SDR status and configuration. 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 sdr_get_status: 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.
sdr_get_status 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 sdr_get_status 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 sdr_get_status. 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.
sdr_get_status 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.
Free to start. No card required.
