Kindora MCP Server

Overview

The Kindora MCP Server provides AI assistants like Claude with access to public funder and nonprofit data (IRS Form 990 filings, Canada's CRA and the UK's 360Giving, funders' own websites) and open grant opportunities. Search 213K+ US foundations, browse 338K+ foundation programs, find open grants, and analyze giving patterns, all through natural conversation.

No account required. The server is free to use and rate limited: 100 requests an hour from a fixed IP address, and 60 an hour plus 200 a day per project for apps hosted where the IP rotates. The full table is under Technical Details.

The connector works without an account. With a free Kindora account you can save the funders you find, track them in a pipeline, and see which fit your organization. Create a free Kindora account

Technical Details

• Server URL: https://mcp.kindora.co/mcp
• Transport: Streamable HTTP
• Authentication: None required (public access)
• Rate Limit: 100 requests per rolling hour per IP address (each semantic-search tool 30, browsing with no query 15 each; 1,500 a month). Apps hosted where the egress IP rotates, such as Supabase Edge Functions: 60 an hour and 200 a day per project, inside shared platform pools. Claude connector traffic has its own pooled tier. Full table and refusal format.
• Data Source: Public IRS Form 990 and 990-PF filings, federal and state grant portals, national charity registers, funders' own websites, and verified open-web reporting
• Coverage: 213K+ US foundations, 338K+ foundation programs, 9.6M+ grant records
• Updates: IRS filings as the IRS publishes them; funder websites re-crawled weekly, with new pages discovered monthly
• Data Use: free for fundraising research and AI-assistant use; redistribution, embedding in other products, bulk extraction, and AI training require a partner agreement — see the Kindora Data Use Policy

Identify Your Integration

If you're building a recurring or custom integration against the Kindora MCP server, include an X-Kindora-Client header with your app's name on every request. It helps us recognize your integration in anonymized traffic analytics and reach out before changing behavior it depends on.

X-Kindora-Client: your-app-name

The header is voluntary and never a credential: it does not raise a limit for anyone. On a platform that rotates its egress IP (Supabase Edge Functions today), a labeled app is not counted against the pool shared by unlabeled apps, but its own per-project quota and the platform-wide daily ceiling still apply. Allowed characters: letters, digits, spaces, and ._/@:+-, up to 64 characters.

Data and Privacy

What the Server Accesses

• Public records: IRS Form 990 and 990-PF filings, the IRS Business Master File, CRA (Canada) and 360Giving (UK) data, and funders' websites and job boards
• Foundation names, addresses, and EINs
• Financial information (assets, revenue, grants)
• Grant recipient information
• Open grant opportunities from foundations, federal agencies, and state portals
• NTEE classification codes

What the Server Does NOT Do

• Does not collect personal information about you, except what you choose to send through start_kindora_profile: the brief about your organization and your name, role and work email, used to email you a link. A search query is stored as you typed it.
• Does not access your Claude conversations or files
• Does not sell or share your data — anonymized search queries are logged only to improve results and prevent abuse
• Does not track you across days or build individual profiles — usage analytics rely on an anonymized identifier that resets daily
• Does not change any data, except that start_kindora_profile records your request and sends you one email, only after you approve the brief

Rate Limiting: IP addresses are hashed for rate limit enforcement and not stored in plaintext. Rolling-hour counters are kept for the hour plus a minute; daily and monthly volume counters until a few days after the end of the calendar month they belong to.

Links in results: Links to kindora.co in tool results carry a source tag (utm_source=mcp and utm_medium=claude or agent) so Kindora can count visits and signups that come from the connector. If you open one and it is your first visit in 30 days, kindora.co keeps a note in your browser, for up to 30 days, that you arrived from the connector; if you sign up in that time, that source is recorded with your signup. The tag carries nothing about you or your conversation.
