Tools

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

Environment variables

NameDescription
VAARA_DB
Optional		Path to the SQLite audit DB. Defaults to vaara_audit.db in the working directory.
VAARA_API_KEY
Optional		Optional shared secret. When set, every tool call must include _api_key in its arguments. Leave unset for single-tenant stdio deployments where process isolation is enough.
