AI agents call get_devices to retrieve information from Zont without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves device information from a ZONT heating system. Even without explicit description, 'get_devices' is a quintessential read operation that queries system state without side effects.
From the tool's definition Tool name 'get_devices' follows a retrieval pattern (get_*). Empty description limits certainty, but naming convention and context within a monitoring/diagnostic server (alongside get_boiler_errors, get_device_state, get_energy_analysis, etc.) strongly…
Attacks that exploit this kind of access
get_devices. It is categorised as a Read tool in the Zont MCP Server, which means it retrieves data without modifying state.
Register the Zont MCP server in PolicyLayer and add a rule for 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 Zont. Nothing to install.
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 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 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.
get_devices is provided by the Zont MCP server (mab2908/zont-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
