Use GrantCue from Claude or ChatGPT

The connector lets an AI assistant search GrantCue's public data: the open grants anyone can see on the site and the public foundation profiles. It is free and needs no GrantCue account or sign-in. It never sees your account, your organization or your saved grants, and it cannot change anything.

Add it

1. In Claude, open Customize, then Connectors, and choose + Add, then Add custom connector. In ChatGPT on the web, open Plugins and choose the plus button, then Add custom MCP server; if your ChatGPT shows Apps instead of Plugins, open Settings, then Apps, and choose Create. Menu names change from time to time, and ChatGPT's custom servers depend on your ChatGPT plan.
2. Name it GrantCue and enter the address https://www.grantcue.com/api/v1/mcp. When asked how to sign in, choose No sign in in Claude or No authentication in ChatGPT.
3. Ask the assistant for grants or foundations in your own words, for example "open grants for rural libraries in Pennsylvania".

What it can do

• Search open grants and open one grant's public details.
• Search foundations by name, place or EIN and open a foundation's giving, its largest grants and how to apply.

To save a grant, track deadlines or see fit scores, open GrantCue itself: the connector does not reach your account.
