Three ways in
Claude on the web or desktop
Add this address as a custom connector in claude.ai:
https://mcp.fundersindex.com/mcp
Claude sends you to a sign-in page. Paste your club's key there once and the connector stays signed in.
Claude Code
Install the plugin from the marketplace, then give it your key.
- Set
FUNDERS_INDEX_KEYto your club's key, andFUNDERS_INDEX_URLto this site's address with no trailing slash. - Run
/plugin marketplace addwith the repository address the district gave you. - Run
/plugin install funders-index.
Anything else (REST)
Send your key as Authorization: Bearer <your key> to any path under /api/v1. The OpenAPI description needs no key, and the reference lists every endpoint.
Five questions to try
- Which funders gave the most to arts organizations in Evanston?
- Which causes in Skokie receive the least money compared with how many organizations work on them?
- Show how one foundation's giving changed year by year, as a chart.
- Who else funds the organizations that a given foundation supports?
- List gifts over $25,000 in Winnetka in the most recent year, grouped by cause.
What it will and will not do
- It lists organizations only: nonprofits, foundations, companies and public bodies.
- Gifts from individuals are counted in totals but the people are never named.
- It does not draft or send outreach. You decide who to contact and how.
- It reads data and cannot change any of it.
Getting a key
Each club has its own key. To request one, write to the district contact with your club's name.
