Charity Registry

Remote MCP server exposing 7 million+ registered charities across 65+ countries, sourced from official government registries (IRS, Charity Commission, ACNC, and dozens more). Read-only, no key required to start.

Endpoint: https://giveradar.com/mcp/ (JSON-RPC 2.0 over HTTPS) Docs: giveradar.com/mcp | Manifest: /.well-known/mcp.json

Tools

Plus resources/list / resources/read for full schema.org JSON-LD per charity (incl. FAQs). All tools are read-only (readOnlyHint: true).

Connect

This repo includes a tiny zero-dependency stdio bridge (index.js) that forwards the MCP stdio transport to the hosted endpoint, so any stdio MCP client can use it. Add to Claude Desktop's claude_desktop_config.json:

{
  "mcpServers": {
    "giveradar": {
      "command": "npx",
      "args": ["-y", "github:matt-timmermans/giveradar-mcp"]
    }
  }
}

Clients with native streamable-HTTP support can connect directly to https://giveradar.com/mcp/. You can also use the generic remote bridge npx -y mcp-remote https://giveradar.com/mcp/.

Optional: set GIVERADAR_API_KEY=gr_xxxxx in the environment to raise the daily quota and unlock Pro fields.

Try it

curl -s -X POST -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"verify_charity","arguments":{"country":"US","id_value":"13-1760110"}}}' \
  https://giveradar.com/mcp/

Quotas & tiers

Authenticate with Authorization: Bearer gr_xxxxx - get a key at giveradar.com/api. Email, phone, and officer names are never exposed, at any tier.
