AI agents call list_floating_ips to retrieve information from Hcloud without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about floating IP resources without modifying, deleting, or executing anything. It is a pure information retrieval operation. The blast radius of misuse is minimal—an agent could enumerate floating IP resources, which may expose infrastructure topology but poses no direct risk to data or operations.
From the tool's definition Tool name 'list_floating_ips' and description 'List all floating IPs' indicate a retrieval operation with no side effects. The verb 'list' is explicitly called out in the schema as a Read category example.
Attacks that exploit this kind of access
List all floating IPs. It is categorised as a Read tool in the Hcloud MCP Server, which means it retrieves data without modifying state.
Register the Hcloud MCP server in PolicyLayer and add a rule for list_floating_ips: 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 Hcloud. Nothing to install.
list_floating_ips 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 list_floating_ips 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 list_floating_ips. 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.
list_floating_ips is provided by the Hcloud MCP server (xodus-co/hcloud-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
