Environment variables
  • CANVAS_PROVIDER_TYPEDataCanvas staging, on by default: stage=true or a canvas_id on an openfda_search_* tool or openfda_lookup_ndc stages the matched records as a SQL table for the openfda_dataframe_* tools. The DuckDB binding ships with the server. Set to 'none' to disable.
  • OPENFDA_DATAFRAME_DROP_ENABLEDEnable openfda_dataframe_drop, which deletes a table staged on a DataCanvas. Off by default; applies only when DataCanvas is enabled (CANVAS_PROVIDER_TYPE=duckdb).
  • OPENFDA_MIRROR_ENABLEDServe exact-key lookups for drug/label, drug/ndc, drug/enforcement, and drug/drugsfda from a local bulk mirror instead of the API. Off by default; the initial harvest runs out-of-band via the mirror:init script.
  • OPENFDA_MIRROR_PATHDirectory holding one SQLite file per mirrored dataset.
  • OPENFDA_MIRROR_FALLBACK_LIVEFall back to the live API when the mirror is cold, missing the record, or failing. Disable to fail loudly instead.
  • OPENFDA_MIRROR_REFRESH_TIMEOUT_MSWall-clock budget for one scheduled refresh before it is aborted. Raise it for drug/label, the only multi-partition dataset.
  • OPENFDA_MIRROR_BASE_URLHost serving the openFDA bulk download manifest. Override only to harvest from a private mirror of the dumps.
  • 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.
