Register the UPS MCP Server MCP server in PolicyLayer and add a rule for track_package: 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.
track_package 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 track_package 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 track_package. 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.
track_package is provided by the UPS MCP Server MCP server (roscoej/ups-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
