Environment variables
  • STATS_EXPLORER_STREAM_MBCSV/TSV/Parquet files above this size (MB) are streamed in parallel passes; any size works. Default 512.
  • STATS_EXPLORER_CACHEKeep columns read from large files for fast follow-up questions: ask (default), on or off.
  • STATS_EXPLORER_GUIDEDon (default): classify each request and follow the six-step workflow for hypothesis tests. off: expose the individual test tools directly.
  • STATS_EXPLORER_CONFIRM_SELECTIONSon (default): the user confirms every column, chart type and report section before anything runs. off: run with the AI's choices.
  • STATS_EXPLORER_CONFIRM_VIAauto (default): forms where the client supports them. chat: always ask in the conversation (recommended for Claude Code).
  • STATS_EXPLORER_JEVIndependent checks by Jev (TypeSafe): off (default), cooperate (the AI calls your Jev MCP server), enforce (Stats Explorer calls the Jev API) or orchestrated (signed decisions from an orchestrator).
  • STATS_EXPLORER_JEV_CHECKPOINTSComma list of plan, conclusions, data. Default plan,conclusions (data sends column names and text samples to Jev).
  • TYPESAFE_API_KEYsecretEnforce mode only: TypeSafe API key Stats Explorer uses to call Jev.
  • STATS_EXPLORER_APPROVAL_SECRETsecretOrchestrated mode only: shared secret (32+ characters) the orchestrator signs decisions with.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
