🚀 Quick Start (5 Minutes)

Prerequisites

• Python 3.12+
• Claude Desktop
• Moralis API Key (free - 40k requests/day)

Step 1: Clone & Install

# Clone repository
git clone https://github.com/vibhudixit123/coinmarketcap_mcp.git
cd coinmarketcap_mcp

# Create virtual environment
python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install dependencies
pip install -r requirements.txt

Step 2: Configure API Key

# Copy environment template
cp .env.example .env

# Add your Moralis API key
nano .env

Add this line:

MORALIS_API_KEY=your_api_key_here

Get your free API key at moralis.io → Dashboard → Web3 APIs

Step 3: Test the Server

python -m src.server

You should see:

============================================================
CoinMarketCap MCP Server (Multi-Chain + Portfolio Edition)
Supported Chains: ethereum, base, polygon, arbitrum...
Total Tools: 12 (8 market + 4 portfolio)
============================================================
Moralis client initialized ✅

Press Ctrl+C if it works. Now configure Claude Desktop!

🖥️ Configure Claude Desktop

Step 1: Find Your Paths

# Get your Python path
which python3
# Example output: /Users/yourname/coinmarketcap_mcp/venv/bin/python3

# Get your project path
pwd
# Example output: /Users/yourname/coinmarketcap_mcp

Step 2: Edit Claude Desktop Config

On Mac:

nano ~/Library/Application\ Support/Claude/claude_desktop_config.json

On Windows:

notepad %APPDATA%\Claude\claude_desktop_config.json

Step 3: Add This Configuration

{
  "mcpServers": {
    "coinmarketcap-portfolio": {
      "command": "/Users/yourname/coinmarketcap_mcp/venv/bin/python3",
      "args": ["-m", "src.server"],
      "cwd": "/Users/yourname/coinmarketcap_mcp",
      "env": {
        "PYTHONPATH": "/Users/yourname/coinmarketcap_mcp",
        "MORALIS_API_KEY": "your_moralis_api_key_here"
      }
    }
  }
}

Replace:

• /Users/yourname/... with YOUR paths from Step 1
• your_moralis_api_key_here with YOUR Moralis API key

Step 4: Restart Claude Desktop

1. Quit Claude Desktop completely (Cmd+Q on Mac, close on Windows)
2. Open Claude Desktop
3. Look for 🔨 hammer icon at the bottom

✅ If you see the hammer icon, it worked!

🌐 Host it as a remote MCP server (multi-user)

You can run this as a public, hosted MCP server that anyone can connect to. It runs the MCP Streamable HTTP transport at /mcp and is multi-user by design: the server stores no Moralis key. Each user supplies their own Moralis API key on every request via the X-Moralis-Key header — so you never pay for their usage and there's nothing to abuse.

The market-data tools use a public CoinMarketCap endpoint and need no key. Only the 4 portfolio tools need a Moralis key, taken from the caller's header.

Run the HTTP transport locally

MCP_TRANSPORT=http PORT=8000 python -m src.server
# Health check:  curl http://localhost:8000/health
# MCP endpoint:  http://localhost:8000/mcp

Deploy to Render (free tier)

1. Push this repo to GitHub.
2. In Render: New → Blueprint, select the repo. The included render.yaml builds the Dockerfile and sets MCP_TRANSPORT=http. (No MORALIS_API_KEY is set on the server — that's intentional.)
3. Deploy. Your server is live at https://<your-app>.onrender.com/mcp.

Any Docker host (Railway, Fly.io, a VPS) works too — just set MCP_TRANSPORT=http and expose the port. Render injects PORT automatically.

How users connect (with their own key)

Clients that support remote MCP servers with custom headers (e.g. Cursor, Cline):

{
  "mcpServers": {
    "coinmarketcap": {
      "url": "https://<your-app>.onrender.com/mcp",
      "headers": { "X-Moralis-Key": "THEIR_OWN_MORALIS_KEY" }
    }
  }
}

For Claude Desktop, connect through the mcp-remote bridge:

{
  "mcpServers": {
    "coinmarketcap": {
      "command": "npx",
      "args": [
        "mcp-remote", "https://<your-app>.onrender.com/mcp",
        "--header", "X-Moralis-Key:THEIR_OWN_MORALIS_KEY"
      ]
    }
  }
}

Each user gets their own free Moralis key at moralis.io.

🐛 Troubleshooting

"Module not found" error

Add PYTHONPATH to your Claude config:

"env": {
  "PYTHONPATH": "/full/path/to/coinmarketcap_mcp"
}

No hammer icon in Claude Desktop

1. Check config file location is correct
2. Verify Python path: which python3
3. Test server manually: python -m src.server
4. View logs: tail -f ~/Library/Logs/Claude/mcp*.log

"MORALIS_API_KEY not found"

Make sure the key is in both:

• .env file in project directory
• Claude Desktop config JSON
