AI agents call get_parameter to retrieve information from Genieacs without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_parameter only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access get_parameter gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Read specific TR-069 parameter values from the GenieACS cache for a device without contacting the CPE. Use this tool to quickly retrieve known parameter values such as firmware version, serial number, uptime, WiFi SSID, or IP addresses. This reads the last-known values stored in the ACS database — the data may be stale if the device has not informed recently. Use refresh_parameter first if you need a guaranteed fresh value from the CPE. The parameter_path can be a single parameter (e.g. "Device.DeviceInfo.SoftwareVersion") or a comma-separated list for multiple parameters. Returns the matching device document fields as JSON. Limitations: only returns data that the ACS has previously collected. If a parameter has never been read from the CPE, it will not appear in the response.. It is categorised as a Read tool in the Genieacs MCP Server, which means it retrieves data without modifying state.
Register the Genieacs MCP server in PolicyLayer and add a rule for get_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.
get_parameter 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 get_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 get_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.
get_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.
