Security Report

4.2
Use Caution4.2High Risk

This is a well-structured MCP server with appropriate authentication patterns and no obvious malicious code. The server properly handles API key credential storage, uses environment variables securely, and implements interactive OAuth login. However, there are minor code quality concerns around error handling and input validation that prevent a higher score. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.

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.vcSettings > API Keys and generate a key (starts with sig_).

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"
      }
    }
  }
}

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"
      }
    }
  }
}

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

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

What you're doingCredits
Check your balance, list tracked accounts, manage rules/tagsFree
Preview an account, search, view sectors, pull a report4
New follows, enriched follows, feed, company signals16
Trending scan, VC activity24
Thesis search, webhook setup (then 8/delivery)40
Company deep-dive: overview, funding, convergence, resources, discover, similar VCs60
Founder intelligence100

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.
