This README provides detailed documentation for the AML Watcher MCP server configuration, focusing on the environment arguments used in the claude_desktop_config.json file. It explains each argument, how to set or modify its values, and how to add new arguments if needed.

Overview

The AML Testing MCP server is a Node.js application built with TypeScript that connects to the AML Watcher API to perform searches for individuals based on their names. It is designed to run as a command-line tool and integrates with Claude Desktop via the Model Context Protocol (MCP).

🌐 Environment Arguments

Below is a detailed explanation of each environment argument specified in the env section of the claude_desktop_config.json. Each argument includes its purpose, type, default value, constraints, and instructions for setting or modifying its value.

| Argument | Type | Required | Default Value | Description | |----------------|---------|----------|----------------|---------------------------------------------------------------------------- | | API_KEY | String | Yes | N/A | The API key for authentication. | | COUNTRIES | Array | No | N/A | Array of countries to filter reports. Note: ISO 3166-1 alpha-2 country codes are supported. Example: "COUNTRIES":"[US]". | | PER_PAGE | Integer | No | 5 | The maximum number of results to return. | | MATCH_SCORE | Integer | No | 70 | Match accuracy level (0–100). Not applicable for "Adverse Media" category. | | RCA_SEARCH | Boolean | No | True | Whether to search within Relatives and Close Associates (RCA). | | ALIAS_SEARCH | Boolean | No | True | Whether to search within aliases. |

You can define custom parameters inside the env section of your configuration file. These parameters are passed to the Docker container as environment variables.

🛠️ How to Add Environment Variables

To customize the search behavior, you can add, remove or modify environment variables in the env section of the claude_desktop_config.json. Ensure the variable names match those expected by the server.

For example:

"env": {
  "API_KEY": "your_api_key",
  "PER_PAGE": "3",
  "COUNTRIES":"[UK,USA]"
}

🚀 Installation and Setup

Install the Package:

npm install @amlwatcher-modelcontextprotocol/aml_watcher_mcp

Integrate with Claude Desktop:

• Update claude_desktop_config.json as shown above.
• Ensure the npx command is available in your environment.

💡Tip: If a variable is missing, the server uses the default value listed above.
