Overview

AI-generated overview

Lets an assistant search live federal grant listings on Grants.gov, read full opportunity details, and explain eligibility codes.

What you can do
Provides four tools over a remote endpoint. search_grants queries live Grants.gov opportunities with filters such as keyword, applicant type, category, instrument, agency and Assistance Listing. get_grant returns one listing in full by opportunity id or number, including status, agency, dates, award ceiling and floor, funding totals, cost sharing and eligible applicants. grants_closing_soon lists deadlines within the next 1 to 120 days, and eligibility_explainer decodes applicant eligibility codes in plain words.
When to use it
Useful when helping a small business, nonprofit, tribe or local government find federal funding, compare opportunities, track upcoming deadlines, or understand whether an applicant type qualifies for a listing.
Requirements
A remote streamable HTTP endpoint; no packages, environment variables or headers are declared. No authentication is declared. Network access to the endpoint is needed.
Before you install
Results come from Grants.gov and users must confirm every detail on the official listing before applying; each result carries its listing link. Treat returned dates, amounts and eligibility as informational rather than authoritative.

Installation

In SourceWeft

  1. Open Small Business Funding Finder in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.modernmustardseed%2Ffunding-finder/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

search_grants

Search federal grants

Search live federal funding opportunities on Grants.gov. Results come from Grants.gov, and users must confirm every detail on the official listing before applying; each result carries its listing link. Filter by keyword, applicant type (small businesses, 501(c)(3) and other nonprofits, tribes, local governments, individuals and more), category, award instrument, agency, Assistance Listing number, status (posted by default, or forecasted) and close date range. Returns the total matches and each listing with id, number, title, agency, posted and close dates, days left and URL. Sort by relevance (default with a keyword), closing_soonest (default without one) or newest. Results are cached for 10 minutes.

83% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
