9 tools. 3 can modify or destroy data without limits.
1 destructive tool with no built-in limits. Policy required.
Last updated:
Financial operations (send_money) can move real money. An agent caught in a loop could drain accounts before anyone notices.
Write operations (login_with_api_key, request_payment_link) 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 My Smithery App. Every tool call checked against your policy before it executes — so your agent can do its job without breaking things.

Yes. The My Smithery App server exposes 1 financial tools including send_money. 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 My Smithery App server has 2 write tools including login_with_api_key, request_payment_link. 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.
9 tools across 3 categories: Financial, Read, Write. 6 are read-only. 3 can modify, create, or delete data.
One line change. Instead of running the My Smithery App server directly, prefix it with Intercept: intercept -c paracetamol951-my-smithery-app.yaml -- npx -y @paracetamol951/my-smithery-app. Download a pre-built policy from policylayer.com/policies/paracetamol951-my-smithery-app 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.
