Quickstart

Install

First, obtain your Ntropy API key by creating an account on ntropy.com. Make sure to replace YOUR_NTROPY_API_KEY below with your actual API key.

Run the server with uvx

uvx ntropy-mcp --api-key YOUR_NTROPY_API_KEY

Claude Desktop

The Claude Desktop configuration file is usually located at:

On MacOS: ~/Library/Application\ Support/Claude/claude_desktop_config.json

On Windows: %APPDATA%/Claude/claude_desktop_config.json

Add the following to the configuration file if using uvx:

  "mcpServers": {
    "ntropy-mcp": {
      "command": "uvx",
      "args": [
        "ntropy-mcp",
        "--api-key",
        "YOUR_NTROPY_API_KEY"
      ]
    }
  }

and the following if using docker:

"mcpServers": {
  "ntropy-mcp": {
    "command": "docker",
    "args": [
      "run",
      "-i",
      "--rm",
      "ntropy-mcp"
      "--api-key",
      "YOUR_NTROPY_API_KEY"
    ]
  }
}

Example Usage

Check Connection

# Check if your API key is valid and the Ntropy API is accessible
connection_status = check_connection()
print(connection_status)

Create and Update Account Holders

# Create a new account holder
account_holder = create_account_holder(
    id="user123",
    type="individual",
    name="John Doe"
)

# Update an existing account holder
updated_account = update_account_holder(
    id="user123",
    name="John Smith"
)

Enrich Transactions

# Enrich a single transaction
enriched_transaction = enrich_transaction(
    id="tx123",
    description="AMAZON.COM*MK1AB6TE1",
    date="2023-05-15",
    amount=-29.99,
    entry_type="debit",
    currency="USD",
    account_holder_id="user123",
    country="US"
)

# Bulk enrich multiple transactions
transactions = [
    {
        "id": "tx124",
        "description": "NETFLIX.COM",
        "date": "2023-05-16",
        "amount": -13.99,

        "currency": "USD",
        "account_holder_id": "user123"
    }
]
enriched_transactions = bulk_enrich_transactions(transactions)
