Frontrun MCP Server

VC follow intelligence for AI agents. Track what top investors follow on X — detect new follows, convergence signals, and trending companies before they're announced.

33 tools. Version 2.5.2.

Setup (1 minute)

Option A: OAuth login (recommended)

No API key needed. Log in with your frontrun.vc account:

# Step 1: Log in — opens browser, saves credentials locally
npx frontrun-mcp-server --login

# Step 2: Auto-configure your client
npx frontrun-mcp-server --setup         # Claude Desktop
npx frontrun-mcp-server --setup-code    # Claude Code (uses `claude mcp add`)

Credentials are saved to `~/.frontrun/credentials.json`. Other commands:

npx frontrun-mcp-server --status   # Check auth status
npx frontrun-mcp-server --logout   # Clear saved credentials

Option B: Hosted endpoint (no install)

The server is also hosted at `https://www.frontrun.vc/mcp` (streamable HTTP). Point any

remote-capable MCP client at it with your API key:

claude mcp add --transport http frontrun https://www.frontrun.vc/mcp --header "Authorization: Bearer sig_your_key_here"

Option C: Manual API key

If you prefer to use an API key directly, go to frontrun.vc → Settings > API Keys and generate a key (starts with `sig_`).

Claude Code

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

Or add to `.mcp.json` in any project:

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

Claude Desktop

Add to your config file:

• macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
• Windows: `%APPDATA%\Claude\claude_desktop_config.json`

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

Cursor

Add to `.cursor/mcp.json` in your project:

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

Any MCP-compatible client

FRONTRUN_API_KEY=sig_your_key_here npx frontrun-mcp-server

Start asking questions

Open your AI tool and try:

> "What's trending in my tracked accounts this week?"

What can I ask?

Here are real prompts that work out of the box. Just type them into Claude Code, Claude Desktop, or Cursor.

Daily deal flow

• "What are the trending companies this week?"
• "Show me what my tracked VCs followed in the last 48 hours"
• "Any convergence signals? Who are multiple VCs following independently?"

Deep research

• "Tell me everything about @hitdotone — who founded it, what they're building, and who's backing them"
• "Who are the founders of @someproject and what's their background?"
• "What funding has @tempofinance raised?"

Discovery

• "Find me early-stage DeFi companies that my tracked VCs are following but I'm not tracking yet"
• "What sectors are getting the most attention from VCs right now?"
• "Search for stablecoin startups in the follow graph"

Portfolio monitoring

• "Track @a16zcrypto and @paradigm"
• "Show me a16zcrypto's recent follow activity and what sectors they're focused on"
• "Find VCs with similar follow patterns to @multicoin"

Custom intelligence

• "Create a rule to flag any stablecoin neobank companies"
• "Tag @hitdotone as a portfolio candidate"
• "Show me all entities matching my stablecoin rule from the last 7 days"

How it works

Frontrun monitors the X (Twitter) follow graphs of VCs and investors you choose to track. When a VC follows a new account, Frontrun detects it, classifies the entity (startup, protocol, founder, etc.), and makes it queryable through AI.

The signal: VCs typically follow companies 2-8 weeks before a funding announcement. Convergence — multiple VCs independently following the same account — is the strongest signal.

Receipts: @techdollarhq flagged at 13 followers, $3M pre-seed announced 123 days later · @orthogonal_sh flagged 184 days before its $4.3M round led by Pantera · @rialto_xyz flagged at 18 followers, 26 days before its Robinhood partner announcement.

What you're paying for: Every response is computed intelligence, not raw data. Sectors are classified by AI, convergence is detected algorithmically, and company profiles are synthesized from multiple sources.

Pricing

API + MCP access is included with the Pro plan ($99/mo) — it comes with 10,000 credits every month, and you can add more (or turn on auto-refill) at frontrun.vc/api/billing. Each query costs credits:

A typical daily check-in (feed + convergence + a few company deep-dives) runs ~300 credits — an included month covers it more than 30x over. Agent-scale usage is what auto-refill is for.

All available tools

The agent has access to these tools automatically. You don't need to call them by name — just ask your question and the agent picks the right tool.

# Set your key
export FR_KEY="sig_your_key_here"

# Check your account
curl -sL -H "X-API-Key: $FR_KEY" "https://frontrun.vc/v1/status"

# What's trending?
curl -sL -H "X-API-Key: $FR_KEY" "https://frontrun.vc/v1/trending?since=168h"

# Convergence signals
curl -sL -H "X-API-Key: $FR_KEY" "https://frontrun.vc/v1/convergence?since=168h"
