Quick Start
Claude Desktop / Claude Code
Add to your MCP configuration:
{
"mcpServers": {
"chainanalyzer-aml": {
"command": "npx",
"args": ["-y", "chainanalyzer-mcp"],
"env": {
"CHAINANALYZER_API_KEY": "tfk_your_api_key"
}
}
}
}
From Source
git clone https://github.com/rascal-3/chainanalyzer-mcp.git
cd chainanalyzer-mcp
npm install
npm start
Authentication
Choose one of three modes:
1. API Key (Subscription)
Get a tfk_ API key from chain-analyzer.com (Pro plan).
{
"env": {
"CHAINANALYZER_API_KEY": "tfk_your_api_key"
}
}
2. x402 USDC Payment (Pay-Per-Request)
No account needed. Pay with USDC on Base or Solana per request.
{
"env": {
"X402_PRIVATE_KEY": "your_wallet_private_key",
"X402_NETWORK": "base"
}
}
Requires the x402 npm package: npm install x402
3. Dev Mode
No authentication. Works when the ChainAnalyzer server has X402_ENABLED=false.
{
"env": {
"CHAINANALYZER_BASE_URL": "http://localhost:3000"
}
}
Environment Variables
| Variable | Description | Required |
|---|---|---|
CHAINANALYZER_API_KEY |
tfk_ API key (subscription auth) |
One of API key or x402 |
X402_PRIVATE_KEY |
Wallet private key for USDC payments | One of API key or x402 |
X402_NETWORK |
Payment network: base or solana (default: base) |
No |
CHAINANALYZER_BASE_URL |
API base URL (default: https://chain-analyzer.com) |
No |
Example Usage
Once configured, ask your AI agent:
"Check if this Ethereum address is sanctioned: 0x1234..."
"Analyze the risk score for this Solana wallet: ABC123..."
"Trace the fund flow of this Bitcoin transaction and check for mixing patterns"
"Screen these 20 addresses for AML compliance"
The agent will automatically call the appropriate ChainAnalyzer tools.
