ncats-arax from k-dense-ai/scientific-agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add k-dense-ai/scientific-agent-skills/ncats-arax@v1.2Pins v1.2 in mdr.lock. Pin the fingerprint instead.

Queries the NCATS Translator ARAX production API for bounded, typed, provenance-rich one-hop and endpoint-pinned two-hop biomedical knowledge-graph relationships. Use for Biolink-constrained RTX-KG2 lookup, explicit selected-provider ARAX federation, separate entity normalization, qualifier-aware graph traversal, and inspection of TRAPI edge bindings, publications, and knowledge-source provenance. Do not use for inference, ranking, open-ended pathfinding, clinical guidance, or sensitive queries.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NCATS ARAX Use ARAX as a constrained knowledge-graph lookup service. Submit reviewed CURIEs and explicit Biolink types, preserve the exact TRAPI exchange, inspect query-edge bindings and provenance, and treat every returned path as a candidate for subsequent verification. Read [query-contract.md](references/query-contract.md) before constructing a query. Read [output-schema.md](references/output-schema.md) when interpreting saved artifacts, warnings, provenance, or partial results. ## Safety boundary - Use only public, nonsensitive research questions. ARAX status facilities may expose query and caller metadata even when `store=false` is requested. - Do not submit patient information, confidential research questions, unpublished compound programs, or proprietary target hypotheses. - Do not present a returned path as a validated mechanism or clinical recommendation. - Report a zero as "not returned under these constraints," never as evidence that no relationship exists. - Describe position as unscored response order, never rank. - Verify important candidates with literature and authoritative databases separately. ## Workflow …

How to install
mdr add k-dense-ai/scientific-agent-skills/ncats-arax@sha256:f15f9f9a149a942aThe line at the top of this page pins the label v1.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
