30 tools. 16 can modify or destroy data without limits.
5 destructive tools with no built-in limits. Policy required.

Financial operations (create_refund, pay_order, send_invoice) can move real money. An agent caught in a loop could drain accounts before anyone notices.
Destructive tools (cancel_sent_invoice, cancel_subscription) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Write operations (accept_dispute_claim, create_invoice, create_order) 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 PayPal. 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 @paypal/paypal-mcp-server create_refund:
rules:
- action: deny Financial tools should be explicitly enabled per use case, not open by default.
cancel_sent_invoice:
rules:
- action: deny Destructive tools should never be available to autonomous agents without human approval.
accept_dispute_claim:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
generate_invoice_qr_code:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
Yes. The PayPal server exposes 3 financial tools including create_refund, pay_order, send_invoice. 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.
Yes. The PayPal server exposes 2 destructive tools including cancel_sent_invoice, cancel_subscription. These permanently remove resources with no undo. Intercept blocks destructive tools by default so they never reach the upstream server.
The PayPal server has 11 write tools including accept_dispute_claim, create_invoice, create_order. 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.
30 tools across 4 categories: Destructive, Financial, Read, Write. 14 are read-only. 16 can modify, create, or delete data.
One line change. Instead of running the PayPal server directly, prefix it with Intercept: intercept -c paypal.yaml -- npx -y @@paypal/paypal-mcp-server. Download a pre-built policy from policylayer.com/policies/paypal 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.
