AI agents use set_parameter to create or modify resources in Genieacs. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call set_parameter repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Genieacs.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access set_parameter gives an agent. Each links to the full case and the policy that stops it:

Set one or more TR-069 parameter values on a CPE device through GenieACS. Use this tool to change device configuration such as WiFi SSID, management server URL, periodic inform interval, or any writable TR-069 parameter. The parameter_values argument must be a JSON array of tuples, where each tuple is [parameterPath, value] or [parameterPath, value, xsdType]. Example: [["InternetGatewayDevice.LANDevice.1.WLANConfiguration.1.SSID","MySSID","xsd:string"]]. Valid xsd types include xsd:string, xsd:boolean, xsd:unsignedInt, xsd:int, xsd:dateTime. If the type is omitted, GenieACS infers it from the value. The task is queued and a connection request is sent to the CPE for immediate execution. Returns the raw ACS JSON response confirming the task. Limitations: the CPE must be reachable for immediate execution; otherwise the task remains queued until the next periodic inform. Not all parameters are writable — the CPE will fault if you attempt to set a read-only parameter. Use refresh_parameter or genieacs://device/{id} first to discover valid parameter paths.. It is categorised as a Write tool in the Genieacs MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Genieacs MCP server in PolicyLayer and add a rule for set_parameter: 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 Genieacs. Nothing to install.
set_parameter is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the set_parameter 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 set_parameter. 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.
set_parameter is provided by the Genieacs MCP server (genieacs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
