Discover Switcher devices on the network
AI agents call discover_devices to retrieve information from Switcher MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the local network to identify Switcher KIS devices and return their information. It has no side effects—it does not turn devices on/off, create/delete schedules, or execute arbitrary operations. It is a passive information-gathering action, fitting the 'Read' category.
From the tool's definition Tool name 'discover_devices' and description 'Discover Switcher devices on the network' indicate a discovery/enumeration operation that retrieves information about available devices without modifying or controlling them.

Discover Switcher devices on the network. It is categorised as a Read tool in the Switcher MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Switcher MCP Server MCP server in PolicyLayer and add a rule for discover_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 Switcher MCP Server. Nothing to install.
discover_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 discover_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 discover_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.
discover_devices is provided by the Switcher MCP Server MCP server (liebstein/switcher-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
