Install Chainanalyzer in Claude Code, Cursor or VS Code

Runs npx -y chainanalyzer-mcp on your machine. Read the scan report first; the gateway never runs local packages.

Tools

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

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.
