What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

• source_status

  Use this tool when the user asks whether the OpenNIH corpus is loaded, which official sidecars are available, or how stale the data might be — and before reporting 'no such grant', since corpus_lag_note explains that a grant added to RePORTER after the snapshot cutoff is absent h

• search_grants

  Use this tool when the user asks to find NIH grants — by topic, principal investigator, institution, NIH Institute/Center, activity code, fiscal year, or project number ('what NIH grants exist on CRISPR', 'show me Stanford's R01s in 2022', 'look up 5R01CA036569-02'). This is the

• rank_institutions

  Use this tool when the user asks which institutions get the most NIH money — 'top NIH-funded universities', 'where does NCI money go', 'rank research hospitals by R01 funding'. Each ranked row also yields its entity_id, the canonical institution identifier. Ranks institutions by

• get_pi_profile

  Use this tool when the user asks about one researcher — 'how much NIH funding does Dr. X have', 'list this PI's grants', 'who does she collaborate with'. profile_id is the NIH RePORTER PI identifier carried in grant-search results' pi_profile_id field and is not guessable. Read-o

• get_institution_profile

  Use this tool when the user asks about one named institution — 'what is Harvard's NIH funding history', 'which PIs does this university fund', 'what mechanisms does it win'. entity_id is the canonical institution identifier (from the institution ranking); grant-search results do

• funding_trend

  Use this tool to get yearly NIH funding totals and grant counts. Returns a time series for the whole NIH, one Institute/Center, one activity code, or one institution. Use it when the user asks 'how much NIH funding was awarded in FY2020', 'how has NIH's budget changed over time',

• topic_trend

  Use this tool when the user asks how a research topic has trended over time — 'is CRISPR funding growing', 'how many p53 grants per year', 'when did NIH start funding long COVID'. Returns yearly project-row counts plus recorded award totals for a title keyword match; multi-word q

• activity_code_distribution

  Use this tool when the user asks what KINDS of awards NIH (or one Institute) makes — 'how much goes to R01s vs training grants', 'what share of NCI's portfolio is centers', 'break NIH down by mechanism'. Returns counts and recorded totals per mechanism class (research / career /

• institution_concentration

  Use this tool when the user asks how concentrated or unequal NIH funding is across institutions — 'is NIH money concentrated in a few universities', 'what share do the top 5 take', 'has inequality grown since 2000'. Returns gini, hhi, top5_share and the top-5 institutions over th

• mechanism_mix

  Use this tool when the user asks what mix of award types ONE institution wins — 'is this university mostly R01s or centers', 'how much of its NIH money is training', 'compare two schools' portfolios'. entity_id is the canonical institution identifier (from the institution ranking

• ic_topic_cross

  Use this tool when the user asks what ONE NIH Institute funds in a topic — 'what is NCI spending on immunotherapy', 'does NIMH fund psychedelics research', 'compare NIAID and NCI on vaccines' (call it once per Institute), or ic='ALL' for every IC at once. The response states whic

• funding_growth

  Use this tool when the user asks about the RATE of change rather than the level — 'is this university's NIH funding growing', 'what's the CAGR since 2015', 'who grew fastest'. Returns year-over-year growth plus a window CAGR for one institution (entity_id, the canonical instituti

• search

  Use this tool when a research or connector client needs citation-shaped NIH grant hits for a natural-language query. Returns {"results": [{id, title, text, url}]} where id is the NIH project_num and url is the public OpenNIH grant page. Each record is PROJECT-level, not project-y

• fetch

  Use this tool to retrieve the full record for one NIH grant by its id. Returns {id, title, text, url, metadata} with url set to the public OpenNIH grant page so the client can cite it. This is the citation-record wrapper resolving the canonical row for an id. The record is PROJEC
