README

chainanalyzer-mcp

MCP Server for ChainAnalyzer — multi-chain blockchain AML risk analysis for AI agents.

Scan any address across Bitcoin, Ethereum, Polygon, Avalanche, and Solana for sanctions violations, money laundering patterns, rug pulls, wallet drainers, and more. 76+ detection rules, ML anomaly scoring, and Neo4j graph analysis.

Tools

Tool	Description	Price
`check_address_risk`	AML risk score for any blockchain address	$0.008
`sanctions_check`	OFAC / FATF / JFSA sanctions screening	$0.003
`trace_transaction`	Transaction flow tracing with ML anomaly detection	$0.015
`detect_coinjoin`	CoinJoin / mixing pattern detection (Bitcoin)	$0.01
`cluster_wallet`	Wallet clustering via Neo4j graph analysis	$0.02
`batch_screening`	Batch AML screening (up to 50 addresses)	$0.05

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.

Supported Chains

Bitcoin — OFAC screening, dust attacks, peel chains, CoinJoin detection
Ethereum — 18+ detectors, Neo4j graph analysis, sanctions, mixers
Polygon — Full EVM AML suite, Etherscan V2 compatible
Avalanche — Full EVM AML suite, Routescan API
Solana — Token security (rug pull, honeypot), wallet drainer detection
