Kindora MCP Server

Overview

The Kindora MCP server gives AI assistants such as Claude and ChatGPT funder and nonprofit data from public sources, for grant seekers and the people who help them. Search 270K+ funders, find open grants and RFPs, see who has funded a nonprofit and its peers, research nonprofits, NGOs and social enterprises in the US and other countries, and browse jobs at foundations, all through conversation. Every tool only reads, except two that act only when the person asks: start_kindora_profile sets up a nonprofit on Kindora, and start_connect_profile sets up a person's About you for Kindora Connect.

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

Quick Start

Claude (web or desktop)

Click Customize in Claude's sidebar, open the Connectors tab, search for Kindora, and click + on Kindora Funder Discovery. No URL to paste and no config file. To add it by URL instead, use + Add → Add custom connector and paste https://mcp.kindora.co/mcp; no sign-in is needed.

Kindora is also one of the connectors in Anthropic's Claude for Nonprofits plugin.

ChatGPT

Click Plugins in ChatGPT's sidebar, search for Kindora, and add it. Then start a message with @Kindora, for example: "@Kindora Find open grants for youth mental health in California."

Manual setup: Claude Desktop config file

Add this to your Claude Desktop config file (claude_desktop_config.json):

{
  "mcpServers": {
    "kindora": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote@latest",
        "https://mcp.kindora.co/mcp",
        "--transport",
        "http-only"
      ]
    }
  }
}

Config file location:
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

Claude Code

Run one command in your terminal:

claude mcp add --transport http kindora https://mcp.kindora.co/mcp

Other MCP clients

Any client that connects to remote MCP servers over Streamable HTTP, such as Cursor or VS Code, can use https://mcp.kindora.co/mcp directly, with no key and no sign-in. A client that only starts local servers can reach it through the mcp-remote bridge shown in the Claude Desktop config above.

Available Tools

The free server lists 17 tools. Every one only reads, except start_kindora_profile and start_connect_profile, which record a request and send the person one email after they approve it.

Technical Details

• Server URL: https://mcp.kindora.co/mcp (with or without a trailing slash)
• 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.
• When you hit a limit: a refused call returns a JSON result, not an HTTP error, with "error", "retry_after" (seconds) and "limit". Wait out retry_after before retrying. start_kindora_profile and start_connect_profile also have their own daily caps per email address; a refusal there carries only "error" and "message".
• Data Source: Public sources: IRS Form 990 filings and the IRS Business Master File; Canada's CRA charity filings and register; the Charity Commission for England and Wales; OSCR (Scotland); Australia's ACNC; Kenya's NGO board; 360Giving (UK); ACRI (Italy); IATI; organizations' and funders' own websites; job boards; and government grant listings
• Coverage: 270K+ funders, 214K+ of them US grantmakers; 347K+ funder programs, 52K+ of them open or upcoming; 9.5M+ US 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 filings and the IRS Business Master File, Canada's CRA filings and register, the Charity Commission for England and Wales, OSCR, the ACNC, Kenya's NGO board, 360Giving, ACRI and IATI data, organizations' and funders' websites, job boards, and government grant listings
• Funder and nonprofit names, locations, and registration numbers (EINs and charity numbers)
• 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) or start_connect_profile (the brief about you, your work email and your LinkedIn link), 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 and start_connect_profile record your request and send 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.
