    Why it is in this group

    • The name "grantsgov_get_opportunity" says "get": a word for reading.
    Description, as the server wrote it
    Read the Grants.gov record for up to 5 opportunities, given numeric opportunity ids or opportunity numbers: deadline, funding, eligibility, description, assistance listings, contact, attachments, packages, and latest revision metadata. Lists and narratives are bounded independent pages; follow each record pages continuation to retrieve the remaining section. An opportunity number is resolved across all statuses. A miss or an ambiguous number comes back as an unresolved entry with guidance, not an error.

    Why it is in this group

    • The name "grantsgov_search_opportunities" says "search": a word for reading.
    Description, as the server wrote it
    Search federal funding opportunities on Grants.gov by keyword, agency, applicant eligibility, funding category, funding instrument, assistance listing, opportunity number, posting window (posted_within_days), or closing window (closing_within_days). Returns forecasted and posted opportunities unless statuses says otherwise, each row led by its close date and days remaining, plus facet counts for narrowing. Bare keyword terms are all required; join alternatives with OR, in parentheses when other terms stay required. Rows carry no award amounts or eligibility detail; read those with grantsgov_get_opportunity. Filter codes come from grantsgov_list_reference.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
