Get detailed information about a specific device by IP or MAC address.
AI agents call get_device_info to retrieve information from Network Scanner MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves device metadata by querying network state. It performs a read-only lookup operation with no capacity to modify, delete, or execute actions. However, severity is medium rather than low because detailed device information (IP, MAC, service fingerprints) in the context of a network scanner could enable reconnaissance for malicious purposes if an AI agent is compromised.
From the tool's definition Tool name 'get_device_info' and description 'Get detailed information about a specific device by IP or MAC address' indicate pure data retrieval with no side effects. Descriptor verbs are 'Get' (read operation).
Attacks that exploit this kind of access
Get detailed information about a specific device by IP or MAC address. It is categorised as a Read tool in the Network Scanner MCP MCP Server, which means it retrieves data without modifying state.
Register the Network Scanner MCP server in PolicyLayer and add a rule for get_device_info: 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 Network Scanner MCP. Nothing to install.
get_device_info 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_device_info 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_device_info. 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_device_info is provided by the Network Scanner MCP server (marc-shade/network-scanner-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
