Fetch latest Azure VM pricing from the public Azure Retail Prices API. No authentication required.
AI agents call refresh_azure_pricing 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 queries the Azure Retail Prices API to retrieve current pricing information. It is a read-only operation that retrieves data without modifying, deleting, or executing arbitrary code. The public, unauthenticated nature and fetch-only semantics confirm a Read classification. Severity is low because pricing data is non-sensitive public information, and misuse would result in negligible harm.
From the tool's definition Tool description explicitly states it 'fetches' data from a public API with 'no authentication required'. The action is a retrieval operation with no side effects.

Register the Cloud Cost MCP server in PolicyLayer and add a rule for refresh_azure_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 Cloud Cost MCP. Nothing to install.
refresh_azure_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 refresh_azure_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.
