\n\n---\n\n## Tools\n\nFourteen tools for querying FDA data across drugs, food, devices, animal/veterinary products, and recalls — plus an optional DataCanvas SQL surface for large result sets:\n\n| Tool | Description |\n|:---|:---|\n| `openfda_drug_profile` | One drug name → consolidated FDA profile: identity, label, adverse events, recalls, approval, shortage |\n| `openfda_search_adverse_events` | Search adverse event reports across drugs, food, and devices |\n| `openfda_search_animal_events` | Search adverse event reports for veterinary drugs and devices |\n| `openfda_search_drug_shortages` | Search FDA drug shortage records — status, availability, therapeutic category, manufacturer |\n| `openfda_search_tobacco_reports` | Search problem reports for tobacco products, e-cigarettes, and vaping devices |\n| `openfda_search_recalls` | Search enforcement reports and recall actions across drugs, food, and devices |\n| `openfda_count_values` | Aggregate and tally unique values for any field across any openFDA endpoint |\n| `openfda_describe_fields` | Return searchable field paths for an openFDA endpoint, grouped by category |\n| `openfda_get_drug_label` | Look up FDA drug labeling (package inserts / SPL documents) |\n| `openfda_search_drug_approvals` | Search the Drugs@FDA database for NDA/ANDA application approvals |\n| `openfda_search_device_clearances` | Search FDA device premarket notifications — 510(k) clearances and PMA approvals |\n| `openfda_lookup_ndc` | Look up drugs in the NDC (National Drug Code) Directory |\n| `openfda_dataframe_query` | Run read-only SQL over a result set staged on a DataCanvas (opt-in) |\n| `openfda_dataframe_describe` | List tables and column schemas staged on a DataCanvas (opt-in) |\n\n### `openfda_drug_profile`\n\nResolve one drug name to its FDA identity, then return a consolidated profile in a single call — replacing four or five chained lookups.\n\n- Resolves a brand or generic name to canonical FDA identifiers once (generic name, NDC, RxCUI, SPL set ID), then keys every sub-query off that identity to avoid the identifier drift that breaks naive tool chaining\n- Single-ingredient resolution: a single-drug query won't resolve to a combination product\n- Sections: label highlights, adverse-event summary (top reactions, serious count), recall history, Drugs@FDA approval, and current shortage status\n- Best-effort — a miss on any section returns `null` rather than failing the whole call; use the dedicated tool for a deep dive into any area\n\n---\n\n### `openfda_search_adverse_events`\n\nSearch adverse event reports across drugs, food, and devices. Use to investigate safety signals, find reports for a specific product, or explore reactions by demographics.\n\n- Category selection: `drug`, `food`, or `device` — each returns different field schemas\n- Elasticsearch query syntax for filtering by product, reaction, seriousness, date range\n- Pagination via `limit` (up to 1000) and `skip` (up to 25000)\n- Formatted output includes report ID, seriousness, patient demographics, reactions, drugs with characterization/indication/route, and all remaining fields\n\n---\n\n### `openfda_count_values`\n\nAggregate and tally unique values for any field across any openFDA endpoint. Returns ranked term-count pairs sorted by count descending.\n\n- Works across all 20 openFDA endpoints (drugs, food, devices, animal/veterinary, tobacco, other)\n- Use `.exact` suffix on field names for whole-phrase counting\n- Optional `search` filter to scope the aggregation\n- Returns up to 1000 terms per query\n\n---\n\n### `openfda_search_recalls`\n\nSearch enforcement reports and recall actions across drugs, food, and devices.\n\n- Supports `enforcement` (all categories) and `recall` (devices only) endpoints\n- Filter by classification (Class I/II/III), recalling firm, reason, status\n- Formatted output includes recall number, classification, product description, reason, distribution pattern\n\n---\n\n### `openfda_search_device_clearances`\n\nSearch FDA device premarket notifications — 510(k) clearances and PMA approvals.\n\n- Two pathways: `510k` (174K+ records, most common) and `pma` (higher-risk devices)\n- Filter by applicant, product code, advisory committee, device name\n- Formatted output adapts to pathway: 510(k) shows K-number/clearance type, PMA shows supplement info\n\n---\n\n### `openfda_get_drug_label`\n\nLook up FDA drug labeling (package inserts / SPL documents). Check indications, warnings, dosage, contraindications, active ingredients, or any structured label section.\n\n- Search by brand name, generic name, manufacturer, or set ID\n- Formatted output dynamically renders all label sections and openfda metadata present in the record\n- Large sections are automatically truncated to keep output readable\n- Default limit of 5 — labels are large documents\n\n---\n\n### `openfda_search_drug_approvals`\n\nSearch the Drugs@FDA database for drug application approvals (NDAs and ANDAs). Returns application details, sponsor info, and full submission history.\n\n- Filter by brand name, sponsor, submission type, review priority\n- Formatted output includes products with active ingredients, dosage forms, routes, and marketing status\n- Full submission history with type, status, date, and review priority\n- Pagination via `limit` (up to 1000) and `skip` (up to 25000)\n\n---\n\n### `openfda_lookup_ndc`\n\nLook up drugs in the NDC (National Drug Code) Directory. Identify drug products by NDC code, find active ingredients, packaging details, or manufacturer info.\n\n- Search by product NDC, brand name, generic name, manufacturer, or active ingredient\n- Returns product details, active ingredients with strengths, and packaging information\n- Sortable by listing expiration date or other fields\n\n---\n\n### `openfda_search_animal_events`\n\nSearch adverse event reports for veterinary drugs and devices submitted to the FDA Center for Veterinary Medicine (1.3M+ records).\n\n- Filter by animal species, breed, drug name, VeDDRA reaction term, or seriousness\n- Records include animal details (species, gender, age, weight), administered drugs, reactions, and outcomes\n- Formatted output surfaces key clinical fields; remaining fields rendered via catch-all\n\n---\n\n### `openfda_search_tobacco_reports`\n\nSearch problem reports submitted to the FDA for tobacco products, including e-cigarettes, vaping products, cigarettes, and smokeless tobacco.\n\n- Filter by product type, reported health problems (e.g. seizure, chest pain), product problems (e.g. battery explosion), or non-user involvement\n- Formatted output surfaces products, health effects, product defects, and report counts\n\n---\n\n### `openfda_search_drug_shortages`\n\nSearch FDA drug shortage records (1,700+ entries, refreshed daily). Returns shortage status, availability notes, therapeutic category, dosage form, manufacturer, and timeline.\n\n- Filter by status (`Current`, `Resolved`), therapeutic category, generic name, or manufacturer\n- The `openfda` block carries `brand_name`, `product_ndc`, and `rxcui` for chaining into `openfda_get_drug_label` or `openfda_lookup_ndc`\n- Pagination via `limit` (up to 1000) and `skip` (up to 25000)\n\n---\n\n### `openfda_describe_fields`\n\nReturn the searchable field paths for an openFDA endpoint, grouped by category with type and description. Use before constructing a search query to discover the correct dotted field paths.\n\n- Covers all major endpoints: `drug/event`, `drug/label`, `drug/shortages`, `drug/drugsfda`, `drug/ndc`, `drug/enforcement`, `food/event`, `food/enforcement`, `device/event`, `device/510k`, `device/pma`, `device/recall`, `device/enforcement`, `animalandveterinary/event`, `tobacco/problem`\n- Returns fields grouped by category (identifiers, dates, clinical fields, etc.) with data type and one-line description\n- Complements the reactive field hints that appear in `notice` enrichment when a search returns empty\n\n---\n\n### `openfda_dataframe_query` · `openfda_dataframe_describe`\n\nA DataCanvas SQL surface over staged result sets — **opt-in**, enabled with `CANVAS_PROVIDER_TYPE=duckdb`.\n\n- With canvas enabled, the multi-row search tools page the full matched set (up to openFDA's 25,000-row ceiling) into a DuckDB table and return an inline preview plus a `canvas_id` and `canvas_table`. `openfda_dataframe_query` runs read-only `SELECT` (GROUP BY, SUM/COUNT, joins) across the staged rows; `openfda_dataframe_describe` lists the table and column schemas needed to write valid SQL.\n- Scalar fields are stored as text (`CAST` for numeric math); nested openFDA blocks (`openfda`, `patient`, `products`, …) are JSON columns. Pass a `canvas_id` back into a search tool to accumulate result sets on one canvas for cross-table joins.\n- Off by default — without `CANVAS_PROVIDER_TYPE=duckdb` the search tools return inline results exactly as before and the two dataframe tools report that canvas is disabled. Requires the optional `@duckdb/node-api` dependency; unsupported on Cloudflare Workers.\n\n## Features\n\nBuilt on [`@cyanheads/mcp-ts-core`](https://www.npmjs.com/package/@cyanheads/mcp-ts-core):\n\n- Declarative tool definitions — single file per tool, framework handles registration and validation\n- Unified error handling across all tools\n- Pluggable auth (`none`, `jwt`, `oauth`)\n- Swappable storage backends: `in-memory`, `filesystem`, `Supabase`, `Cloudflare KV/R2/D1`\n- Structured logging with optional OpenTelemetry tracing\n- Runs locally (stdio/HTTP) or on Cloudflare Workers from the same codebase\n\nopenFDA-specific:\n\n- Generic API client for all openFDA endpoints with retry (exponential backoff) and rate-limit awareness\n- Automatic error normalization — 404 returns empty results, 429/5xx retries, 400 provides actionable messages\n- Optional API key support — works without a key (1K requests/day), increases to 120K/day with a free key\n- Optional DataCanvas spillover (`CANVAS_PROVIDER_TYPE=duckdb`) — stage large result sets as DuckDB tables and run SQL via `openfda_dataframe_query`\n\n## Getting Started\n\n### Public Hosted Instance\n\nA public instance is available at `https://openfda.caseyjhand.com/mcp` — no installation required.
