Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

NameDescription
MASKBREAK_API_KEY
Optional, secret
Maskbreak API key for your plan's lookup allowance (100,000 a month on the Free plan). Without it, lookups use the rate-limited keyless endpoint. The older SENTINEL_API_KEY name is still read.
SENTINEL_BASE_URL
Optional
API base URL override, for testing.
