Documentation
Answers, not just records
The Analytics tools do the work an analyst would: join trials, adverse events, labels and recalls, and hand back a finished view.
Drug & company dossiers
One drug or one company on a page: trials by phase, what reads out next, trials open past their estimated completion, stopped trials and why, FAERS trend, label changes, recalls.
asset_dossier company_dossier
Label gap
FAERS disproportionality signals (PRR, ROR) for a drug, checked against every brand's current label — which reported reactions the label never names.
label_gap
Class compare
Every drug in a mechanism or class side by side on FAERS, so you can tell a class effect from one drug's problem — with the protein target and PDB structures.

Federated Search
Federated search across MAUDE, FAERS, ClinicalTrials.gov, DailyMed, openFDA SPL, FDA Recalls, ChEMBL, and PubChem
Search adverse events, clinical trials, drug labels, recalls, and chemistry together — by keyword or by meaning — in one call.
Live
Analytics
Drug and company analytics over FAERS, DailyMed, ClinicalTrials.gov, FDA Recalls and ChEMBL
Answers, not records — drug and company dossiers, FAERS signals missing from labels, and class-effect comparisons.
Live
MAUDE
Manufacturer and User Facility Device Experience
Query FDA medical-device adverse event reports — by keyword or by meaning — in natural language.
Live
FAERS
FDA Adverse Event Reporting System
Search 20+ years of reported adverse drug events — drugs, reactions, outcomes, and who reported them.
Live
ClinicalTrials.gov
ClinicalTrials.gov study registry (via CTTI AACT)
Search and analyze the world's clinical trial registry — by keyword or by meaning — in natural language.
Live
DailyMed
DailyMed FDA Structured Product Labeling (SPL)
Search and analyze official FDA drug labels — by keyword or by meaning — in natural language.
Live
FDA Recalls
FDA Enforcement Reports (Recalls)
Search FDA recall and enforcement actions across drugs, devices, food, and biologics.
Live
openFDA SPL
openFDA Structured Product Labeling (drug labels)
Search FDA drug labels from the openFDA JSON dump — by keyword or by meaning.
Live
ChEMBL
ChEMBL Bioactivity Database (EMBL-EBI)
Search 2.9M bioactive molecules — by target, mechanism, indication, structure, or meaning — in natural language.
Live
PubChem
PubChem Compound (NCBI)
Resolve drug substances to their chemical identity — CID, InChIKey, formula, and (where PubChem provides them) UNII and pharmacological action — in natural language.
Live
PDB
RCSB Protein Data Bank (wwPDB)
Search 260K experimentally-determined 3D structures — by organism, bound ligand, UniProt target, method, or meaning — in natural language.
Let your agent do the comparing
Your assistant queries the data directly over MCP — structured results, not scraped web pages — so answers are more accurate and cost far fewer tokens than reading through pages of search results.
One ask, one answer
"Is this a class effect?" becomes a single tool call that compares every drug in the class — not dozens of page loads to read and summarize.
Fewer tokens
No HTML to wade through and no search pages to parse, so answers come back faster and cost less.
Straight from the source
Hits include an official url to the primary record (DailyMed, openFDA, ClinicalTrials.gov, FDA MAUDE, iRES recalls) so you can verify what the agent found.
