Overview

FDA data on drugs, food, devices, and recalls from the openFDA public API. Search adverse events, recalls, drug approvals, and device clearances; look up NDC codes and drug labels; aggregate field counts across any endpoint. Runs as a stdio process, a local Streamable HTTP server, or the public hosted endpoint above.

Credentials it needs

OPENFDA_API_KEYFree API key from open.fda.gov — increases daily limit from 1K to 120K requests.
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_REFRESH_CRONCron expression for the in-process mirror refresh. HTTP transport only; stdio operators run mirror:refresh from the host. Requires the optional node-cron peer dependency.
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').
OPENFDA_API_KEYFree API key from open.fda.gov — increases daily limit from 1K to 120K requests.
MCP_TRANSPORT_TYPESelects the HTTP transport.
MCP_HTTP_HOSTThe hostname for the HTTP server.
MCP_HTTP_PORTThe port to run the HTTP server on.
MCP_HTTP_ENDPOINT_PATHThe endpoint path for the MCP server.
MCP_AUTH_MODEAuthentication mode to use: 'none', 'jwt', or 'oauth'.
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.
