AI agents call get_checkout to retrieve information from Creem without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward read operation that queries checkout session information. The verb 'Retrieve' and the read-only nature of fetching details by ID indicate no side effects or data modification. Severity is low because checkout session metadata retrieval poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'get_checkout' with description 'Retrieve checkout session details by ID' explicitly performs data retrieval with no modification capability.
Attacks that exploit this kind of access
Retrieve checkout session details by ID. It is categorised as a Read tool in the Creem MCP Server, which means it retrieves data without modifying state.
Register the Creem MCP server in PolicyLayer and add a rule for get_checkout: 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 Creem. Nothing to install.
get_checkout 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_checkout 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_checkout. 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.
get_checkout is provided by the Creem MCP server (selenium39/mcp-server-creem). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
