Get shipping rates for a package between two addresses. Returns available service options with prices, transit times, and delivery guarantees. Omit the service code to get rates for ALL available services (shop rates). Common codes: 03=Ground, 02=2nd Day Air, 01=Next Day Air, 12=3 Day Select.
AI agents call get_rates to retrieve information from UPS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
get_rates queries the UPS API to retrieve rate information for specified addresses and service types. It performs no data modification, deletion, or external operations—it only retrieves and displays information. No financial transaction is committed (rates are informational quotes, not actual charges or payment processing).
From the tool's definition Tool retrieves shipping rates and returns available service options with prices and transit times. The verb 'Get' and the description 'Returns available service options' indicate a read-only query operation with no side effects.

It is categorised as a Read tool in the UPS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the UPS MCP Server MCP server in PolicyLayer and add a rule for get_rates: 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 UPS MCP Server. Nothing to install.
get_rates 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_rates 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_rates. 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.
