Search GrantCue from Claude

Once GrantCue is added, Claude can search GrantCue's open grant listings and public foundation profiles while it answers you, and open a grant's details or a foundation's profile. It reads the same listings and profiles anyone can see on grantcue.com, and nothing else.

2. Choose + Add, then Add custom connector.
3. Enter the name GrantCue, paste the address above, and choose Continue.
4. Review the authentication settings Claude found and choose Continue.
5. Under Authentication, choose No sign in. Leave Request headers empty.

Team and Enterprise

An Owner adds the connector for the organization once, then each member connects it:

1. The Owner opens Organization settings, then Connectors, and chooses Add.
2. Point to Custom, choose Web, enter the name GrantCue and the address, and choose Continue.
3. Under Authentication, choose No sign in, then Add.
4. Each member opens Customize, then Connectors, finds GrantCue (marked Custom) and chooses Connect.

Claude's menus change from time to time. Anthropic keeps the current steps in its guide, Get started with custom connectors using remote MCP.

• “Find open grants for youth literacy programs that close in the next 60 days.”

  GrantCue searches its open listings for those words, closing within 60 days, and the assistant lists what comes back: title, funder, deadline and amount.

• “Show me the full details of the second one.”

  The assistant opens that grant: who can apply, award amounts, key dates and links to the funder’s own pages.

• “List environment grants over $100,000 that county governments can apply for.”

  The search uses the Environment category, a minimum amount and the county government applicant type. Grants whose rules exclude counties are left out.

• “Which Department of Agriculture grants are announced but not open yet?”

  It searches forecasted grants from that agency, so you can prepare before they open.

• “Which foundations mainly give in Ohio and say how to apply?”

  It lists foundations whose largest share of giving goes to Ohio and whose latest 990-PF says how to apply, largest givers first.

• “Tell me about the first one: its median grant, where it gives and how to apply.”

  The assistant opens the foundation’s public profile: giving by year, typical and median grant, the states it gives to most, its 25 largest grants and what its filing says about applying.

If Claude answers from its own knowledge instead, ask it to use GrantCue by name, for example “Use GrantCue to find…”.

• See your GrantCue account, saved grants, pipeline, tasks or deadlines. It cannot tell you what your organization saved.
• Add a grant to your pipeline, or create, change or delete anything in GrantCue.
• Score grants for your organization. Fit and readiness scores are in the GrantCue app.
• Write a proposal. The assistant may write text for you, but the connector only supplies listings and profiles.
• Return every grant a foundation reported. It returns the 25 largest; the full list, with search and export, comes with a free GrantCue account.
• List every foundation. A foundation search needs a name, a city or state, an EIN, the state a foundation gives to, or the "says how to apply" filter.

• A grant search returns up to 25 grants a page, and only the first 100 results of one search can be reached. Narrow the search to see others.
• A foundation search returns 10 foundations a page, up to 10 pages.
• Long text is shortened: a grant's description, for example, at 2,500 characters.
• Each IP address can make 1,000 requests a minute, of which 300 can be searches or lookups. Over the limit, the connector asks the app to wait and try again.
• Grants come from GrantCue's catalog: Grants.gov, SBIR.gov topics, 188 state and state-agency sources across 49 states and the District of Columbia, and selected local, foundation and corporate programs.
• Foundation profiles cover private foundations that paid at least $1,000,000 and made at least 5 grants, and the community foundations and other charities that report grants on Form 990 Schedule I.
• Listings come from funders and change. Check the funder's own page before you apply.

The connector receives only the request Claude sends, which is the tool to use and its search details (words, filters, a grant ID or an EIN), and the IP address the request comes from, normally Anthropic's server. It does not receive your conversation, uses no cookies, and is not linked to any GrantCue account. Its log records which tool ran and how many results it returned, not your search words. Anthropic handles your conversation under its own privacy policy.

Full details are in section 16 of the GrantCue Privacy Policy.
