Overview

The frontrun-mcp-server MCP server connects AI agents to Frontrun’s VC follow intelligence for X accounts. It monitors tracked investors, detects new follows and convergence, and provides company, founder, funding, sector, and VC-pattern research. Install it with npx and authenticate through Frontrun OAuth or an API key, or use the hosted streamable HTTP endpoint. Reach for it when you need to monitor investor activity, discover companies, or query custom classifications and alerts.

Use cases

  • Monitor tracked VCs for new follows
  • Find companies followed by multiple investors
  • Research founders, funding, and company signals
  • Discover entities matching an investment thesis
  • Create rules and webhooks for follow events

Key features

How Frontrun MCP Server works

What frontrun-mcp-server does

The frontrun-mcp-server MCP server exposes Frontrun’s investor-follow data and intelligence to AI agents. It focuses on the X follow graphs of selected venture capital firms and investors. When tracked accounts follow new profiles, Frontrun makes those changes available for analysis, including entity classification, sector grouping, and overlap between investors.

Use it for deal-flow monitoring, early company discovery, portfolio research, and investor-pattern analysis. The data supports questions about trending entities, recent follows, funding, founders, company resources, social signals, and sectors. It also supports personalized discovery: an agent can identify accounts followed by tracked VCs that are not yet in your own tracking list.

How it works

You first add X accounts to a tracked list. Frontrun then monitors their follow activity and provides the resulting data through MCP tools. The service can classify discovered entities as categories such as startups, protocols, or founders, and can apply rules you define. Convergence queries identify entities followed independently by multiple tracked accounts.

The server is designed for natural-language use. Instead of selecting a tool manually, you can ask an MCP client for recent activity, a company profile, or companies matching an investment thesis. The agent chooses among the available tools.

Setup and configuration

The frontrun-mcp-server MCP server can run locally through npx or be accessed at https://www.frontrun.vc/mcp over streamable HTTP. For local use, install Node.js tooling capable of running npx frontrun-mcp-server.

OAuth is the recommended local setup. Run npx frontrun-mcp-server --login to open a browser and save credentials at ~/.frontrun/credentials.json. The --setup option configures Claude Desktop, while --setup-code uses claude mcp add for Claude Code. --status checks authentication and --logout removes saved credentials.

API-key authentication is another option. Generate a key in Frontrun under Settings > API Keys, then provide it as FRONTRUN_API_KEY for a local server or as a Bearer header for the hosted endpoint. API and MCP access are included with the Pro plan, listed as $99 per month with 10,000 monthly credits. Tool calls consume different credit amounts depending on the operation.

Tools and capabilities

The available tools cover five main areas:

  • Tracking accounts, previewing accounts, and checking status or usage.
  • Reviewing new follows, snapshots, enriched follows, convergence, trends, feeds, sectors, searches, thesis matches, recommendations, and reports.
  • Researching companies, founders, signals, resources, and funding.
  • Examining VC activity and finding investors with similar follow patterns.
  • Managing classification rules, tags, and webhooks for new-follow or convergence events.

The same functionality is also exposed through REST endpoints under https://frontrun.vc/v1.

Limitations and notes

Access is account-based and requires Frontrun authentication, either through saved OAuth credentials or an API key. The hosted endpoint also requires a remote-capable MCP client. Usage is metered with credits: account management operations are free, while research, signal, company, founder, thesis, and webhook operations have stated costs.

Frequently Asked Questions about Frontrun MCP Server

frontrun-mcp-server is an MCP server that connects AI agents to Frontrun’s VC follow intelligence for X accounts. Its main tools track investors, detect new follows and convergence, search entities, analyze companies and founders, inspect funding, classify results, manage tags and rules, and configure webhooks.

Install it by running `npx frontrun-mcp-server` through your MCP client configuration. For OAuth, run `npx frontrun-mcp-server --login`, then use `--setup` for Claude Desktop or `--setup-code` for Claude Code. You can also use the hosted endpoint without a local install.

Yes, frontrun-mcp-server works with Cursor through a project `.cursor/mcp.json` configuration. Add the server command, pass `FRONTRUN_API_KEY`, and start the MCP server with `npx frontrun-mcp-server`.

Authenticate with Frontrun OAuth or an API key. OAuth saves credentials locally after `--login`; API-key setups provide a key beginning with `sig_` through `FRONTRUN_API_KEY` or an Authorization Bearer header for the hosted endpoint.

You can track X accounts belonging to VCs and investors, then query their follow activity. The server can show new follows, overlapping follows, trends, sector breakdowns, company details, investor patterns, and accounts followed by tracked VCs that you do not yet monitor.
