// WHAT CAN GO WRONG

Write operations (generate_dkim_config, generate_dmarc_record, generate_fix_plan) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.

// RECOMMENDED RULES

Rate limit write operations

generate_dkim_config:
  rules:
    - rate_limit: 30/hour

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

analyze_drift:
  rules:
    - rate_limit: 60/minute

Controls API costs and prevents retry loops from exhausting upstream rate limits.

// FAQ

How do I prevent bulk modifications through Blackveil Dns? +

The Blackveil Dns server has 8 write tools including generate_dkim_config, generate_dmarc_record, generate_fix_plan. 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.

How many tools does the Blackveil Dns MCP server expose? +

51 tools across 2 categories: Read, Write. 43 are read-only. 8 can modify, create, or delete data.

How do I add Intercept to my Blackveil Dns setup? +

One line change. Instead of running the Blackveil Dns server directly, prefix it with Intercept: intercept -c com-blackveilsecurity-dns.yaml -- npx -y @blackveil-dns. Download a pre-built policy from policylayer.com/policies/com-blackveilsecurity-dns and adjust the limits to match your use case.
