Get a buyer
AI agents call get_my_purchases to retrieve information from Kreato MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves existing purchase information for the authenticated user. There are no side effects, no data modification, no code execution, and no financial transactions. While the server context involves Web3 monetization, this specific tool only queries data.
From the tool's definition Tool name 'get_my_purchases' and description 'Get a buyer' indicate retrieval of purchase history data without modification or execution. This is a read-only query operation.

Get a buyer. It is categorised as a Read tool in the Kreato MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Kreato MCP Server MCP server in PolicyLayer and add a rule for get_my_purchases: 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 Kreato MCP Server. Nothing to install.
get_my_purchases 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_my_purchases 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_my_purchases. 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_my_purchases is provided by the Kreato MCP Server MCP server (kreatospace/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
