Compare VM/instance pricing across AWS, Azure, GCP, and OCI. Finds instances matching your vCPU and memory requirements.
AI agents call compare_compute 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 compares publicly available pricing data across cloud providers based on user-specified compute requirements. It performs a read-only query operation with no side effects, no code execution, no data modification, and no financial commitments.
From the tool's definition Tool description: 'Compare VM/instance pricing across AWS, Azure, GCP, and OCI. Finds instances matching your vCPU and memory requirements.' The verb 'compare' and 'finds' indicate data retrieval and querying of pricing information.
Attacks that exploit this kind of access
Compare VM/instance pricing across AWS, Azure, GCP, and OCI. Finds instances matching your vCPU and memory requirements. 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_compute: 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_compute 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_compute 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_compute. 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_compute 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.
