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"}}}' \
