MCP Server

Getting Started

Connect Launch Fast to Claude or another MCP-compatible AI assistant. Ask it to research markets, examine seller data, and summarize Amazon performance. You do not have to export spreadsheets.

Start Here

Use the video above for the visual walkthrough. The written setup below is split into two paths:

Claude Connectors

For claude.ai and Claude Desktop. Paste the server URL and sign in through OAuth.

API key clients

For Claude Code, Cursor, Windsurf, or config-based MCP clients.

Server URL

Use this remote MCP server for each setup path:

https://launchfastlegacyx.com/api/mcp/server

Before You Start

You must have a Launch Fast account with MCP enabled.
MCP access is available on Growth and Scale entitlements.
Use Claude Connectors if you set up claude.ai or Claude Desktop.
Use API key clients if your app asks for an MCP server config or headers.
Product research tools can work before connecting an Amazon account.
Connect Amazon data before you use Amazon Account and Amazon Ads report tools.

Amazon account connections happen inside Launch Fast.

In Launch Fast, go to Settings → Authentication. Connect Seller Central/SP-API or Amazon Ads. Wait for the report data to sync. Then ask Claude to analyze account or ad performance.

Claude And Claude Desktop Setup

Use this path for claude.ai and Claude Desktop. It is the simplest setup because Claude opens a browser sign-in flow and stores a connector authorization.

Open Connector Settings

Open Claude connector settings in claude.ai or Claude Desktop.

Paste The Server URL

https://launchfastlegacyx.com/api/mcp/server

Claude opens a browser-based Launch Fast OAuth flow. Sign in to Launch Fast and approve the connector. Claude receives a connector authorization, not your Launch Fast password.

Enable The Connector For The Chat Or Project

After connecting, make sure Launch Fast is enabled in the Claude chat, project, or tool settings where you want to use it.

API Key Setup For Developer Clients

Generate MCP API keys in Launch Fast from Settings → Authentication. Then send the key in the X-LaunchFast-API-Key header.

Use this path for Claude Code, Cursor, Windsurf, or an MCP client. Select it when the client asks for JSON configuration or custom HTTP headers.

Create An API Key

In Launch Fast, open Settings → Authentication, find the MCP API keys area, and create a new key. Copy it immediately and keep it private.

Add The MCP Server Config

Use this config shape for Claude Code, Cursor, Windsurf, or another remote HTTP MCP client:

{
  "mcpServers": {
    "launchfast": {
      "type": "http",
      "url": "https://launchfastlegacyx.com/api/mcp/server",
      "headers": {
        "X-LaunchFast-API-Key": "YOUR_API_KEY"
      }
    }
  }
}

Restart Your MCP Client

Restart the app or reload the MCP configuration so the Launch Fast server is available.

Keep API keys private.

If a key is exposed, revoke it in Launch Fast settings and create a replacement key.

Test The Connection

Paste this into Claude after connecting Launch Fast:

Research the Amazon market for silicone spatulas and show the strongest opportunities, risks, pricing, reviews, and revenue trends.

Claude must call Launch Fast and return real market or product data. A successful answer must mention specific market/product signals such as prices, reviews, revenue estimates, product examples, or trend context.

If Claude gives a generic answer, confirm:

Launch Fast is connected.
The connector is enabled for the current chat or project.
Your Launch Fast plan includes MCP access.
API key clients send X-LaunchFast-API-Key.
