API Documentation

ICON MCP v101 Website: https://pro-api.coinmarketcap.com
API Documentation:

Available Tools

This server provides the following tools:

example_tool: Placeholder tool (to be implemented)

Note: Replace example_tool with actual ICON MCP v101 API tools based on the documentation.

Installation

Using Docker (Recommended)

Clone this repository:

git clone https://github.com/Traia-IO/icon-mcp-v101-mcp-server.git
cd icon-mcp-v101-mcp-server

Set your API key:

export ICON_MCP_V101_API_KEY="your-api-key-here"

Run with Docker:
```
./run_local_docker.sh
```

Using Docker Compose

Create a .env file with your configuration:

Server's internal API key (for payment mode)

ICON_MCP_V101_API_KEY=your-api-key-here

Server payment address (for HTTP 402 protocol)

SERVER_ADDRESS=0x1234567890123456789012345678901234567890

Operator keys (for signing settlement attestations)

MCP_OPERATOR_PRIVATE_KEY=0x1234567890abcdef... MCP_OPERATOR_ADDRESS=0x9876543210fedcba...

Optional: Testing mode (skip settlement for local dev)

D402_TESTING_MODE=false PORT=8000


2. Start the server:
```bash
docker-compose up

Manual Installation

Install dependencies using uv:
```
uv pip install -e .
```
Run the server:

ICON_MCP_V101_API_KEY="your-api-key-here" uv run python -m server


## Usage

### Health Check

Test if the server is running:
```bash
python mcp_health_check.py

Using with CrewAI

from traia_iatp.mcp.traia_mcp_adapter import create_mcp_adapter_with_auth

# Connect with authentication
with create_mcp_adapter_with_auth(
    url="http://localhost:8000/mcp/",
    api_key="your-api-key"
) as tools:
    # Use the tools
    for tool in tools:
        print(f"Available tool: {tool.name}")
        
    # Example usage
    result = await tool.example_tool(query="test")
    print(result)

Authentication & Payment (HTTP 402 Protocol)

This server supports two modes of operation:

Mode 1: Authenticated Access (Free)

Clients with their own ICON MCP v101 API key can use the server for free:

# Request with client's API key
curl -X POST http://localhost:8000/mcp \
  -H "Authorization: Bearer CLIENT_ICON_MCP_V101_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"method":"tools/call","params":{"name":"example_tool","arguments":{"query":"test"}}}'

Flow:

Client provides their ICON MCP v101 API key
Server uses client's API key to call ICON MCP v101 API
No payment required
Client pays ICON MCP v101 directly

Mode 2: Payment Required (Paid Access)

Clients without an API key can pay-per-use via HTTP 402 protocol:

# Request with payment proof (x402/d402 protocol)
curl -X POST http://localhost:8000/mcp \
  -H "X-PAYMENT: <base64_encoded_x402_payment>" \
  -H "Content-Type: application/json" \
  -d '{"method":"tools/call","params":{"name":"example_tool","arguments":{"query":"test"}}}'

Flow:

Client makes initial request without payment
Server returns HTTP 402 with PaymentRequirements (token, network, amount)
Client creates EIP-3009 transferWithAuthorization payment signature
Client base64-encodes payment and sends in X-PAYMENT header
Server verifies payment via traia_iatp.d402.mcp_middleware
Server uses its INTERNAL ICON MCP v101 API key to call the API
Client receives result

D402 Protocol Details

This server uses the traia_iatp.d402 module for payment verification:

Payment Method: EIP-3009 transferWithAuthorization (gasless)
Supported Tokens: USDC, TRAIA, or any ERC20 token
Default Price: $0.001 per request (configurable via DEFAULT_PRICE_USD)
Networks: Base Sepolia, Sepolia, Polygon, etc.
Facilitator: d402.org (public) or custom facilitator

Environment Variables for Payment Mode

# Required
ICON_MCP_V101_API_KEY=your_internal_icon-mcp-v101_api_key  # Server's API key (for payment mode)
SERVER_ADDRESS=0x1234567890123456789012345678901234567890  # Server's payment address

# Required for Settlement (Production)
MCP_OPERATOR_PRIVATE_KEY=0x1234...  # Private key for signing settlement attestations
MCP_OPERATOR_ADDRESS=0x5678...      # Operator's public address (for verification)

# Optional
D402_FACILITATOR_URL=https://facilitator.d402.net  # Facilitator service URL
D402_FACILITATOR_API_KEY=your_key  # For private facilitator
D402_TESTING_MODE=false  # Set to 'true' for local testing without settlement

Operator Keys:

MCP_OPERATOR_PRIVATE_KEY: Used to sign settlement attestations (proof of service completion)
MCP_OPERATOR_ADDRESS: Public address corresponding to the private key
Required for on-chain settlement via IATP Settlement Layer
Can be the same as SERVER_ADDRESS or a separate operator key

Note on Per-Endpoint Configuration: Each endpoint's payment requirements (token address, network, price) are embedded in the tool code. They come from the endpoint configuration when the server is generated.

How It Works

Client Decision:
- Has ICON MCP v101 API key? → Mode 1 (Authenticated)
- No API key but willing to pay? → Mode 2 (Payment)
Server Response:
- Mode 1: Uses client's API key (free for client)
- Mode 2: Uses server's API key (client pays server)
Business Model:
- Mode 1: No revenue (passthrough)
- Mode 2: Revenue from pay-per-use (monetize server's API subscription)
