AI agents call victron_network_scan to retrieve information from Victron Tcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Network scanning and device discovery are read-only operations that retrieve information about available services and devices on the local network. No data is modified, no commands are executed on target devices, and no destructive or financial operations occur. This aligns with the 'Read' category for retrieval and querying operations.
From the tool's definition Tool name and description indicate network scanning and discovery functionality: 'Scan the local network to find Victron GX devices.

Scan the local network to find Victron GX devices. Probes for Modbus TCP (port 502) and MQTT (port 1883) services, then verifies Victron devices via Modbus. Use this when you don\. It is categorised as a Read tool in the Victron Tcp MCP Server, which means it retrieves data without modifying state.
Register the Victron Tcp MCP server in PolicyLayer and add a rule for victron_network_scan: 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 Victron Tcp. Nothing to install.
victron_network_scan 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 victron_network_scan 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 victron_network_scan. 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.
victron_network_scan is provided by the Victron Tcp MCP server (lubosstrejcek/victron-tcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
