8 tools. 7 can modify or destroy data without limits.
1 destructive tool with no built-in limits. Policy required.
Last updated:
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.
Intercept sits between your agent and Ra Pay. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.
npx -y @policylayer/intercept scan -- npx -y @rapay/mcp-server ra_refund:
rules:
- action: deny Financial tools should be explicitly enabled per use case, not open by default.
ra_add_card:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
ra_history:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
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. Intercept lets you block financial tools by default or set per-tool rate limits.
The Ra Pay server has 6 write tools including ra_add_card, ra_balance, ra_dashboard. Set rate limits in your policy file -- for example, rate_limit: 10/hour prevents an agent from making more than 10 modifications per hour. Intercept enforces this at the transport layer.
8 tools across 3 categories: Financial, Read, Write. 1 are read-only. 7 can modify, create, or delete data.
One line change. Instead of running the Ra Pay server directly, prefix it with Intercept: intercept -c ra-pay.yaml -- npx -y @@rapay/mcp-server. Download a pre-built policy from policylayer.com/policies/ra-pay and adjust the limits to match your use case.
Starter policies available for each. Same risk classification, same one-command setup.
Set budgets, approvals, and hard limits across MCP servers.
