Guide

MCP server setup

The LatestRounds MCP server lets you query live funding data in natural language inside Claude, Cursor, or any MCP-compatible AI client. It runs locally via npx — no separate server to host.

Requirements

  • • Node.js 18 or higher
  • • A valid LatestRounds API key (from your dashboard)
  • • Claude Code, Cursor, or another MCP-compatible client

Claude Code (.mcp.json)

Add to .mcp.json in your project root, then run /mcp inside Claude Code to connect.

.mcp.json
{
  "mcpServers": {
    "latestrounds": {
      "command": "npx",
      "args": ["-y", "latestrounds-mcp@latest", "--api-key", "YOUR_API_KEY"]
    }
  }
}

Cursor / other MCP clients

Add to your MCP settings file. Include cwd if your client requires it.

MCP settings
{
  "mcpServers": {
    "latestrounds": {
      "command": "npx",
      "args": ["-y", "latestrounds-mcp@latest", "--api-key", "YOUR_API_KEY"],
      "cwd": "/path/to/your/project"
    }
  }
}
