GrantSonar MCP server

• dismiss_grantFree

  Dismiss a grant from YOUR active feed, or restore it (dismissed=false). Reversible. Requires your API key.

• draft_application_sectionFree

  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_grantFree

  Fetch the full detail of a single grant opportunity by its GrantSonar grant_id (UUID), including synopsis, eligibility, deadlines, and award amounts.

• get_my_applicationFree

  Fetch one of YOUR grant applications (status + every section draft) by application_id or grant_id. Requires your API key.

• list_my_applicationsFree

  List YOUR organization's grant applications (id, grant title, status, document type, last updated). Requires your API key.

• list_my_matchesFree

  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_grantFree

  Save a grant to YOUR pipeline, or set its status to pursuing/applied. Reversible. Requires your API key. Mirrors the dashboard Save button.

• search_grantsFree

  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_sectionwrite actionFree

  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.
