MCP-native secret scanner in one fast Rust binary: engine, CLI, and MCP server. Finds API keys and secrets, skips known-public fixtures, verifies live keys with a real provider call, and applies env-var rewrites. Privacy invariant: the raw secret never leaves disk.
Setup
Choose your client, copy the config, then fill in any required environment variables.
