Environment variables
  • FRANKFURTER_BASE_URLFrankfurter API base URL. Override for local testing or self-hosted instances.
  • FX_TIMESERIES_CANVAS_THRESHOLD_DAYSDay range above which fx_get_timeseries considers automatic DataCanvas staging for SQL analytics. Without canvas_id, series that fit the preview remain inline. DataCanvas is on by default; CANVAS_PROVIDER_TYPE=none returns ranges inline when canvas_id is omitted and rejects explicit staging.
  • FX_ENABLE_CANVAS_DROPEnable fx_dataframe_drop, which permanently removes one staged table or view from a DataCanvas. Disabled by default; the tool is not registered (absent from tools/list) until set to true.
  • MCP_LOG_LEVELSets the minimum log level for output (e.g., 'debug', 'info', 'warn').

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