Overview

AI-generated overview

Read-only remote MCP server for searching public US grants and foundation profiles built from IRS filings.

What you can do
  • Search the public grant catalog by filters and page through up to 100 matches
  • Read a single grant in full: dates, amounts, eligibility and funder links
  • Search foundations with public profiles by name, city, state, EIN or giving state
  • Read a foundation profile: giving totals, typical and median grant, giving by year, places, largest grants
When to use it
Useful when an assistant needs to look up US funding opportunities or research a foundation's giving patterns from public data, without signing in or touching any account.
Requirements
A remote streamable HTTP endpoint; no packages, environment variables, headers or sign-in are declared.
Before you install
Results are limited to what GrantCue lists publicly; grants not publicly listed are not found, and a foundation's full grant history is never available. Grant text comes from funders and IRS filings, so figures should be verified against the funder's own pages.

Installation

In SourceWeft

  1. Open GrantCue 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.grantcue%2Fgrantcue/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

Parametersgrant_idrequired

search_funders

Search foundations

Search the foundations that have a public GrantCue profile (built from the latest Form 990-PF, or Form 990 Schedule I for community foundations and other grantmaking charities), largest givers first. Search by name, city, state or EIN, by the state they mainly give to, or for those that publish how to apply. Form 990 grantmakers are found by name, state or EIN, after the 990-PF matches, each marked source_form "990". Returns 10 per page.

Parameterspagequeryrecipient_stateaccepting_applications

get_funder

Get a foundation

A foundation’s public GrantCue profile, from the latest Form 990-PF, or Form 990 Schedule I for community foundations and other grantmaking charities: giving totals, typical and median grant, giving by year, where it gives, the 25 largest grants its latest filings report, and for a 990-PF filer how to apply. For a Form 990 funder: its kind, the latest tax year, totals and the top 10 recipients (yearly totals); Form 990 does not say whether it accepts applications. Only foundations with a public profile, and funders with a Schedule I return, are found. It never returns the full list of reported grants.
