## Tools (9)

- `dismiss_grant`: Dismiss a grant from YOUR active feed, or restore it (dismissed=false). Reversible. Requires your API key.
- `draft_application_section`: Generate an AI first-draft for one section of YOUR application, grounded in the funding notice and your org profile, and save it into that section (prior content snapshotted first). Requires a paid API key. This is the only tool that runs the grant writer, so it is metered heavily. Returns the drafted text. Use get_my_application for section_keys.
- `get_grant`: Fetch the full detail of a single grant opportunity by its GrantSonar grant_id (UUID), including synopsis, eligibility, deadlines, and award amounts.
- `get_my_application`: Fetch one of YOUR grant applications (status + every section draft) by application_id or grant_id. Requires your API key.
- `list_my_applications`: List YOUR organization's grant applications (id, grant title, status, document type, last updated). Requires your API key.
- `list_my_matches`: List YOUR organization's scored grant matches — the same personalized matches shown on your GrantSonar dashboard. Requires your API key. Returns match tier, score, reasons, pipeline status, and a URL per grant.
- `save_grant`: Save a grant to YOUR pipeline, or set its status to pursuing/applied. Reversible. Requires your API key. Mirrors the dashboard Save button.
- `search_grants`: Search open grant opportunities in the GrantSonar corpus (federal, state, and foundation grants). Uses semantic similarity over a plain-English description of the project or need, with a keyword fallback. Returns title, agency, deadline, award amounts, similarity score, and a GrantSonar URL per hit.
- `update_application_section`: Write content into one section of YOUR grant application (replace or append). Requires your API key. The prior draft is snapshotted to version history first, so this is recoverable. Use get_my_application to see section_keys.
