Frontrun Server

Give AI agents native access to the Frontrun API. Track what VCs follow on X in real time — detect new follows, convergence signals, and trending companies across your monitored set.

Works with any MCP-compatible client: Claude Code, Claude Desktop, Cursor, Windsurf, and more.

Setup

Step 1: Get your API key

Sign up at frontrun.vc → Settings → API Keys.

Step 2: Connect

Claude Code (one command):

claude mcp add frontrun -e FRONTRUN_API_KEY=your_api_key --scope user -- npx frontrun-mcp-server

Done. Start Claude Code and ask: "What's trending in VC follows this week?"

Claude Desktop — add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "frontrun": {
      "command": "npx",
      "args": ["frontrun-mcp-server"],
      "env": {
        "FRONTRUN_API_KEY": "your_api_key"
      }
    }
  }
}

Cursor — add to .cursor/mcp.json:

{
  "mcpServers": {
    "frontrun": {
      "command": "npx",
      "args": ["frontrun-mcp-server"],
      "env": {
        "FRONTRUN_API_KEY": "your_api_key"
      }
    }
