Connect Vantafin to AI tools that speak the Model Context Protocol (MCP) - such as Claude, Claude Code and Cursor - so they can query Vantafin data directly: live quotes, fundamentals, SEC filings, earnings transcripts, screeners, macro data and more. The server uses the same fast data layer that powers Vantafin chat, so answers are accurate and grounded in the underlying filings and figures.

Cursor

Add the server to ~/.cursor/mcp.json (or a project .cursor/mcp.json), then enable it in Settings → MCP.

{
  "mcpServers": {
    "vantafin": {
      "url": "https://mcp.vantafin.com/mcp",
      "headers": {
        "Authorization": "Bearer vf-live-your_api_key"
      }
    }
  }
}

Claude Code

Register the remote server from your terminal:

claude mcp add --transport http vantafin https://mcp.vantafin.com/mcp \
  --header "Authorization: Bearer vf-live-your_api_key"

Claude Desktop

Claude Desktop reaches remote servers through the mcp-remote bridge. Add this to your claude_desktop_config.json and restart Claude.

{
  "mcpServers": {
    "vantafin": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.vantafin.com/mcp",
        "--header",
        "Authorization: Bearer vf-live-your_api_key"
      ]
    }
  }
}

Verify the connection

List the available tools with a raw request:

curl -X POST https://mcp.vantafin.com/mcp \
  -H "Authorization: Bearer vf-live-your_api_key" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
