UnrealUGC MCP Server README | AllMCPs

UnrealUGC MCP Server

The official Model Context Protocol server for UnrealUGC. It gives MCP-compatible assistants eleven typed tools for browsing creators and models, estimating credit cost, and generating AI UGC video ads.

This repository contains only the public MCP adapter. The UnrealUGC application and backend remain private.

Prerequisites

Node.js 20 or newer
An UnrealUGC API key from Dashboard → Settings → API Keys

API keys start with usk_live_ and should be stored in your MCP client's environment settings, never committed to a repository.

Local stdio setup

You do not need to install the package globally. MCP clients can launch it with npx.

Claude Desktop

Add this server to your Claude Desktop configuration:

config.json

{
  "mcpServers": {
    "unrealugc": {
      "command": "npx",
      "args": ["-y", "@unrealugc/mcp"],
      "env": {
        "UNREALUGC_API_KEY": "usk_live_..."
      }
    }
  }
}

Claude Code

Terminal

claude mcp add unrealugc --env UNREALUGC_API_KEY=usk_live_... -- npx -y @unrealugc/mcp

Codex

toml

[mcp_servers.unrealugc]
command = "npx"
args = ["-y", "@unrealugc/mcp"]

[mcp_servers.unrealugc.env]
UNREALUGC_API_KEY = "usk_live_..."

Cursor, Windsurf, OpenClaw, and other stdio MCP clients use the same command and environment variable.

Hosted Streamable HTTP setup

Clients that support remote MCP can connect without running a local process:

Authorization: Bearer usk_live_...

See the MCP setup guide for client-specific instructions.

Generation flow

Call list_models and list_creators.
Call estimate_video_cost with the proposed script.
Check get_credits if budget matters.
Call generate_video.
Poll get_video about every 15 seconds, or use UnrealUGC webhooks for completion events.
