Get IIO (Industrial I/O) sensor data for a specific node
AI agents call get_node_iio_data to retrieve information from Sage MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves industrial I/O sensor readings from Sage nodes. The verb 'get' and the context of querying sensor data indicates a read-only operation that merely fetches existing information. There are no side effects, data modifications, code execution, or destructive operations involved.
From the tool's definition Tool name contains 'get_' and description states 'Get IIO (Industrial I/O) sensor data for a specific node' — retrieval of sensor data with no modification, deletion, or execution of arbitrary code.
Attacks that exploit this kind of access
Get IIO (Industrial I/O) sensor data for a specific node. It is categorised as a Read tool in the Sage MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Sage MCP Server MCP server in PolicyLayer and add a rule for get_node_iio_data: 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 Sage MCP Server. Nothing to install.
get_node_iio_data 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_node_iio_data 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_node_iio_data. 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_node_iio_data is provided by the Sage MCP Server MCP server (waggle-sensor/sage-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
