Frontrun

What is Frontrun?

Frontrun is an MCP server providing VC follow intelligence for AI agents. It monitors the X (Twitter) follow graphs of top investors, detecting new follows, convergence signals, and trending companies before they are publicly announced. It is designed for investors, analysts, and anyone tracking early-stage deal flow.

How to use Frontrun?

Set up via OAuth login (npx frontrun-mcp-server --login) or a manual API key from frontrun.vc. After authentication, configure your client using --setup for Claude Desktop or --setup-code for Claude Code. Then ask natural‑language questions such as “What are the trending companies this week?” or “Show me convergence signals.” Frontrun provides 33 tools—all callable automatically by the AI based on your query.

FAQ from Frontrun

What signal does Frontrun detect?

VCs typically follow a company 2–8 weeks before a funding announcement. Convergence—multiple VCs independently following the same account—is the strongest signal.

How do I set up Frontrun?

You can use OAuth login (npx frontrun-mcp-server --login) which opens a browser and saves credentials locally, or obtain a manual API key (starts with sig_) from your frontrun.vc settings. Then configure your client with the provided --setup or --setup-code commands.

How is Frontrun priced?

Each query costs a certain number of credits (e.g., 4 credits for a preview, 60 for a company deep‑dive). Pro plans include 10,000 credits per month, and auto‑refill is available. Checking your balance and managing rules/tags is free.

Where does my data live?

Credentials are stored locally in ~/.frontrun/credentials.json. All API responses are computed intelligence—not raw data—synthesized from multiple sources.

What clients does Frontrun support?

Claude Desktop, Claude Code, Cursor, and any MCP‑compatible client. Configuration examples are provided for each.
