OnCo is a public, cited knowledge graph of oncology. It holds one record per cancer, front, technology, target, treatment or test, company, institution, person, pathway, trial, key paper, journal, pairing, roadmap, bottleneck and idea, with links in every direction and a plain-English summary before the technical layer. Every record carries a date of last check and links to a primary source. The corpus is built from TypeScript records in a public repository and refreshed from PubChem, RCSB PDB, Wikidata, OpenAlex, GLOBOCAN, ClinicalTrials.gov, Europe PMC and openFDA. The same corpus ships as a website, a static JSON API with NDJSON, RDF N-Triples and JSON Schema downloads, per-record Markdown context files, a command-line tool and a Model Context Protocol server. The code is MIT and the data are CC BY-NC 4.0.
