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 2.5.0.

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: 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.

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

Your API key has a credit balance — Pro includes 10,000 credits every month, and you can add more (or turn on auto-refill) at frontrun.vc/api/billing. Each query costs credits:

What you're doing	Credits
Check your balance, list tracked accounts, manage rules/tags	Free
Preview an account, search, view sectors, pull a report	4
New follows, enriched follows, feed, company signals	16
Trending scan, VC activity	24
Thesis search, webhook setup (then 8/delivery)	40
Company deep-dive: overview, funding, convergence, resources, discover, similar VCs	60
Founder intelligence	100

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.
