Financial operations (ra_refund) can move real money. An agent caught in a loop could drain accounts before anyone notices.
Write operations (ra_add_card, ra_balance, ra_dashboard) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.

Yes. The Ra Pay server exposes 1 financial tools including ra_refund. Without a policy, an autonomous agent can call these with no spend caps, no rate limits, and no approval flow. PolicyLayer lets you block financial tools by default, require human approval, or set per-tool rate limits — enforced on every call.
The Ra Pay server has 6 write tools including ra_add_card, ra_balance, ra_dashboard. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Ra Pay.
8 tools across 3 categories: Financial, Read, Write. 1 are read-only. 7 can modify, create, or delete data.
Register the Ra Pay MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.
Starter policies for each. Same risk classification, live on your fleet in minutes.
