AI agents call get_pricing 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 retrieves pricing information from the Hetzner Cloud API, which is a read-only operation. It does not create, modify, delete, or execute any infrastructure changes. There are no financial transactions, destructive actions, or code execution involved. The severity is low because accessing pricing data poses minimal risk to infrastructure or security even if an AI agent calls it unexpectedly.
From the tool's definition Tool name is 'get_pricing' with description 'Get all prices'. The verb 'get' and the read-only nature of pricing retrieval indicate a query operation that retrieves data without modification or side effects.
Attacks that exploit this kind of access
Get all prices. 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 get_pricing: 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.
get_pricing 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_pricing 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_pricing. 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_pricing 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.
