Write operations (vigil_add_travel_plan, vigil_generate_report, vigil_update_alert) 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 Vigil Fraud Alert. 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 @ebenova/vigil-fraud-alert vigil_add_travel_plan:
rules:
- rate_limit: 30/hour Prevents bulk unintended modifications from agents caught in loops.
vigil_analyze_transaction:
rules:
- rate_limit: 60/minute Controls API costs and prevents retry loops from exhausting upstream rate limits.
The Vigil Fraud Alert server has 5 write tools including vigil_add_travel_plan, vigil_generate_report, vigil_update_alert. 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.
13 tools across 2 categories: Read, Write. 8 are read-only. 5 can modify, create, or delete data.
One line change. Instead of running the Vigil Fraud Alert server directly, prefix it with Intercept: intercept -c ebenova-vigil-fraud-alert.yaml -- npx -y @ebenova/vigil-fraud-alert. Download a pre-built policy from policylayer.com/policies/ebenova-vigil-fraud-alert and adjust the limits to match your use case.
Set budgets, approvals, and hard limits across MCP servers.
