How do I install MCP Aml?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does MCP Aml need an API key?

The publisher lists these environment variables: CRYPTOAPIS_API_KEY.

What transport does MCP Aml use?

MCP Aml runs locally over stdio.

@cryptoapis-io/mcp-aml

MCP server for Crypto APIs AML (Anti-Money Laundering) product. Verify addresses and screen transactions for fraud, sanctions, and other AML risk categories.

API Version: Compatible with Crypto APIs version 2024-12-12

Features

Verify whether an address is flagged or associated with fraud, sanctions, ransomware, exploits, darknet markets, or other AML risk categories
Screen a transaction and its participants against AML data, returning risk score, risk band, and flagged addresses with roles/categories/severity
Get an address's exposure to risky entities/categories via the AML exposure graph
List the paths connecting an address to risky entities in the AML exposure graph, with cursor pagination

Prerequisites

Node.js 18+
Crypto APIs account and API key (sign up | get API key)

Installation

npm install @cryptoapis-io/mcp-aml

Or install all Crypto APIs MCP servers: npm install @cryptoapis-io/mcp

Usage

# Run with API key
npx @cryptoapis-io/mcp-aml --api-key YOUR_API_KEY

# Or use environment variable
export CRYPTOAPIS_API_KEY=YOUR_API_KEY
npx @cryptoapis-io/mcp-aml

# HTTP transport (listens on 127.0.0.1; see "Exposing the server beyond localhost")
npx @cryptoapis-io/mcp-aml --transport http --port 3000 --api-key YOUR_API_KEY

Claude Desktop

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "cryptoapis-aml": {
      "command": "npx",
      "args": ["-y", "@cryptoapis-io/mcp-aml"],
      "env": {
        "CRYPTOAPIS_API_KEY": "your_api_key_here"
      }
    }
  }
}

Cursor

Add to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "cryptoapis-aml": {
      "command": "npx",
      "args": ["-y", "@cryptoapis-io/mcp-aml"],
      "env": {
        "CRYPTOAPIS_API_KEY": "your_api_key_here"
      }
    }
  }
}

MCP Inspector

npx @modelcontextprotocol/inspector npx @cryptoapis-io/mcp-aml --api-key YOUR_API_KEY

n8n

Start the server in HTTP mode:

npx @cryptoapis-io/mcp-aml --transport http --port 3000 --api-key YOUR_API_KEY

In your n8n workflow, add an AI Agent node
Under Tools, add an MCP Client Tool and set the URL to http://localhost:3000/mcp

n8n in Docker: localhost inside the container is not your machine. Start the server with --host 0.0.0.0 and MCP_AUTH_TOKEN set (see Exposing the server beyond localhost), use http://host.docker.internal:3000/mcp as the URL, and add an Authorization: Bearer <token> header to the MCP Client Tool credential.

All servers default to port 3000. Use --port to assign different ports when running multiple servers.

Available Tools

`aml`

Action	Description
`verify-address`	Check if an address is flagged for fraud, sanctions, or other AML risk categories. Params: `address`
`screen-transaction`	Screen a transaction and its participants against AML data. Params: `blockchain`, `transactionHash`
`get-address-exposure`	Get an address's exposure to risky entities/categories in the AML exposure graph. Params: `blockchain`, `address`
`list-address-exposure-paths`	List the paths connecting an address to risky entities in the AML exposure graph. Params: `blockchain`, `address`; optional `rootAddress` (only return routes originating from this flagged root address), `limit` (1-50, default 10), `startingAfter` (cursor — pass back the response's `nextStartingAfter` to page)

screen-transaction supports: ethereum, ethereum-classic, binance-smart-chain, bitcoin, bitcoin-cash, dash, dogecoin, litecoin, arbitrum, polygon, avalanche, optimism, base, zcash, xrp, solana, tezos, kaspa, tron.

get-address-exposure and list-address-exposure-paths support a narrower set of 13 chains (no exposure graph for arbitrum, avalanche, base, optimism, tezos, or kaspa): ethereum, binance-smart-chain, ethereum-classic, polygon, tron, bitcoin, bitcoin-cash, litecoin, dogecoin, dash, zcash, xrp, solana.

Note: these are the highest per-call credit cost endpoints in the Crypto APIs suite — verify-address is 200,000 credits, screen-transaction is 500,000 credits per call, get-address-exposure is 200,000 credits per request, and list-address-exposure-paths is 100,000 credits per page.

CLI Arguments

Argument	Description	Default
`--api-key`	Crypto APIs API key	`CRYPTOAPIS_API_KEY` env var
`--transport`	Transport type: `stdio` or `http`	`stdio`
`--host`	HTTP host (use `0.0.0.0` to accept remote connections — requires an auth token with `--api-key`)	`127.0.0.1`
`--auth-token`	Bearer token callers must send (`Authorization: Bearer <token>`); prefer the `MCP_AUTH_TOKEN` env var	`MCP_AUTH_TOKEN` env var
`--allowed-hosts`	Comma-separated `Host` header allowlist for non-loopback binds	—
`--port`	HTTP port	`3000`
`--path`	HTTP path	`/mcp`
`--stateless`	Enable stateless HTTP mode	`false`

HTTP API Key Modes

When using HTTP transport, the server supports two API key modes:

With --api-key: The key is used for all requests. x-api-key request headers are ignored.
Without --api-key: Each request must include an x-api-key header with a valid Crypto APIs key. This enables hosting a public server where each user provides their own key.

# Per-request key mode (multi-tenant)
npx @cryptoapis-io/mcp-aml --transport http --port 3000
# Clients send x-api-key header with each request

Exposing the server beyond localhost

HTTP mode listens on 127.0.0.1 by default, so only processes on the same machine can reach it. To accept connections from other machines or containers, bind explicitly and protect the port:

# Startup-key mode: callers must present the token (the server refuses to start without one)
export MCP_AUTH_TOKEN=$(openssl rand -hex 32)
npx @cryptoapis-io/mcp-aml --transport http --host 0.0.0.0 --port 3000 --api-key YOUR_API_KEY \
  --allowed-hosts mcp.internal.example
# Clients send: Authorization: Bearer $MCP_AUTH_TOKEN

# Per-request key mode: no startup key, every request must carry the caller's own x-api-key
npx @cryptoapis-io/mcp-aml --transport http --host 0.0.0.0 --port 3000

--allowed-hosts restricts the Host header (DNS rebinding protection) when not bound to loopback. Prefer MCP_AUTH_TOKEN over --auth-token: command-line arguments are visible in the process list.

Stdio transport always requires an API key at startup.

Important: API Key Required

Warning: Making requests without a valid API key — or with an incorrect one — may result in your IP being banned from the Crypto APIs ecosystem. Always ensure a valid API key is configured before starting any server.

Remote MCP Server

Crypto APIs provides an official remote MCP server with all tools available via HTTP Streamable transport at https://ai.cryptoapis.io/mcp. Pass your API key via the x-api-key header — no installation required.
