Uranium MCP Server

🚀 Quick Install

A Model Context Protocol (MCP) server for working with portal.uranium.pro - creating and managing NFT collections and assets. This server enables LLMs to interact with blockchain NFTs through a simple, structured interface.

Key Features

• Fast and efficient NFT management. Direct integration with Uranium API for instant operations.
• Multi-collection support. Manage ERC721 and ERC1155 NFT collections seamlessly.
• File-based asset creation. Upload images, videos, audio, and documents directly as NFTs.
• Bulk operations. List and filter assets across multiple collections with pagination.

Requirements

• Node.js 18 or newer
• Uranium API key from portal.uranium.pro
• VS Code, Cursor, Windsurf, Claude Desktop, Goose or any other MCP client

Getting Started

First, install the Uranium MCP server with your client.

Standard config works in most of the tools:

{
  "mcpServers": {
    "uranium": {
      "command": "npx",
      "args": ["uranium-tools-mcp@latest"],
      "env": {
        "URANIUM_API_KEY": "your_api_key_here"
      }
    }
  }
}

Use the Claude Code CLI to add the Uranium MCP server:

claude mcp add uranium npx uranium-tools-mcp@latest

Then set your URANIUM_API_KEY when prompted.

Add to your Claude Desktop configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "uranium": {
      "command": "npx",
      "args": ["uranium-tools-mcp@latest"],
      "env": {
        "URANIUM_API_KEY": "your_api_key_here"
      }
    }
  }
}

Create or edit the configuration file ~/.codex/config.toml and add:

[mcp_servers.uranium]
command = "npx"
args = ["uranium-tools-mcp@latest"]
env = { URANIUM_API_KEY = "your_api_key_here" }

For more information, see the Codex MCP documentation.

Click the button to install:

Or install manually:

Go to Cursor Settings -> MCP -> Add new MCP Server. Name it "uranium", use command type with the command npx uranium-tools-mcp@latest. Add environment variable URANIUM_API_KEY with your API key.

Follow the MCP install guide, use the standard config above with your API key.

Click the button to install:

Or install manually:

Go to Advanced settings -> Extensions -> Add custom extension. Name it "uranium", use type STDIO, and set the command to npx uranium-tools-mcp@latest. Add environment variable URANIUM_API_KEY with your API key. Click "Add Extension".

Click the button to install:

Or install manually:

Go to Program in the right sidebar -> Install -> Edit mcp.json. Use the standard config above with your API key.

Follow the MCP Servers documentation. For example in ~/.config/opencode/opencode.json:

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "uranium": {
      "type": "local",
      "command": [
        "npx",
        "uranium-tools-mcp@latest"
      ],
      "env": {
        "URANIUM_API_KEY": "your_api_key_here"
      },
      "enabled": true
    }
  }
}

Open Qodo Gen chat panel in VSCode or IntelliJ → Connect more tools → + Add new MCP → Paste the standard config above with your API key.

Click Save.

Click the button to install:

Or install manually:

Follow the MCP install guide, use the standard config above. You can also install the Uranium MCP server using the VS Code CLI:

# For VS Code
code --add-mcp '{"name":"uranium","command":"npx","args":["uranium-tools-mcp@latest"],"env":{"URANIUM_API_KEY":"your_api_key_here"}}'

After installation, the Uranium MCP server will be available for use with your GitHub Copilot agent in VS Code.

Follow Windsurf MCP documentation. Use the standard config above with your API key.

Configuration

Environment Variables

• URANIUM_API_KEY (required): Your Uranium API key from portal.uranium.pro
• URANIUM_BASE_URL (optional): API base URL. Defaults to https://gw.urnm.pro

Example Configuration

{
  "mcpServers": {
    "uranium": {
      "command": "npx",
      "args": ["uranium-tools-mcp@latest"],
      "env": {
        "URANIUM_API_KEY": "your_api_key_here"
        // URANIUM_BASE_URL is optional, defaults to https://gw.urnm.pro
      }
    }
  }
}

Local Installation

If you prefer to install locally:

npm install -g uranium-tools-mcp
# or
pnpm add -g uranium-tools-mcp
# or
yarn global add uranium-tools-mcp

Then use uranium-tools-mcp instead of npx uranium-tools-mcp@latest in the configuration.
