Compare object and block storage pricing across all clouds.
AI agents call compare_storage to retrieve information from Cloud Cost MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and presents storage pricing information to enable cost analysis. It has no side effects, does not modify data, does not execute code or commands, does not delete anything, and does not move money. It is purely informational, analogous to a search or query operation on a pricing database.
From the tool's definition Tool performs comparison of pricing data across clouds. The verb 'compare' and the context of a pricing comparison server indicates data retrieval and querying.
Attacks that exploit this kind of access
Compare object and block storage pricing across all clouds. It is categorised as a Read tool in the Cloud Cost MCP MCP Server, which means it retrieves data without modifying state.
Register the Cloud Cost MCP server in PolicyLayer and add a rule for compare_storage: 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 Cloud Cost MCP. Nothing to install.
compare_storage 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 compare_storage 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 compare_storage. 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.
compare_storage is provided by the Cloud Cost MCP server (jasonwilbur/cloud-cost-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
