[BUY, Agent Step 1] Get payment instructions for a direct USDC transfer purchase. Use this if you are an AI agent that cannot sign EIP-712 permits. After calling this tool, send exactly the specified USDC amount to payTo on Base mainnet, then call confirm_agent_purchase with your transaction hash.

AI agents use initiate_agent_purchase to create or modify resources in Real Real Genuine. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call initiate_agent_purchase repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Real Real Genuine.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

[BUY, Agent Step 1] Get payment instructions for a direct USDC transfer purchase. Use this if you are an AI agent that cannot sign EIP-712 permits. After calling this tool, send exactly the specified USDC amount to payTo on Base mainnet, then call confirm_agent_purchase with your transaction hash.. It is categorised as a Write tool in the Real Real Genuine MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Real Real Genuine MCP server in PolicyLayer and add a rule for initiate_agent_purchase: 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 Real Real Genuine. Nothing to install.
initiate_agent_purchase is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the initiate_agent_purchase 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 initiate_agent_purchase. 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.
initiate_agent_purchase is provided by the Real Real Genuine MCP server (https://realrealgenuine.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
