zenmoney-mcp

MCP server wrapping the ZenMoney personal finance API.

Exposes tools (sync, read, search, write, bulk) via the Model Context Protocol over stdio, allowing LLM assistants to interact with your ZenMoney data.

Caution: Using MCP always carries a certain risk to your data, especially in the early stages of adoption. You or other users who decide to try MCP with ZenMoney may want to make backups (including daily backups to Telegram) and restore them to test accounts. See zentable.ru/backup and zentable.ru/backup/restore.

Important: When creating a test account, do it from a different phone or a cloned app. Otherwise, your bank synchronizations may break when you switch back to your main account.

Installation

cargo install zenmoney-mcp

Getting a Token

To use this server, you need a ZenMoney API access token. You can obtain one by creating an application at ZenMoney API and following the OAuth2 flow, or by extracting the token from the ZenMoney web app (see the ZenMoney API documentation for details).

Usage

ZENMONEY_TOKEN=<your-token> zenmoney-mcp

The server performs an initial sync on startup, then serves MCP tools over stdio.

Claude Desktop Integration

Add the following to your Claude Desktop config file:

{

      "env": {
        "ZENMONEY_TOKEN": "your-token-here"
      }
    }
  }
}

Replace your-token-here with your ZenMoney API token, then restart Claude Desktop.

Usage Scenarios

Deduplication of Transactions

Find and remove duplicate transactions by searching for matching payee, amount, and date:

1. list_transactions with date range + payee/amount filters to find potential duplicates
2. Review the results and identify true duplicates
3. delete_transaction to remove duplicates — the response shows full details of the deleted transaction for confirmation

Setting Up Correct Categories

Find uncategorized transactions and assign categories:

1. list_transactions(uncategorized: true) to find all transactions without tags
2. For each: suggest_category(payee: "...") to get ZenMoney's suggestion
3. update_transaction(id: "...", tag_ids: ["..."]) to apply the category
4. Or use prepare_bulk_operations to preview categorizing many transactions, review the preview, then execute_bulk_operations to commit

Monthly Financial Report

Generate a summary of income, expenses, and budgets for a month:

1. list_transactions(date_from: "2025-02-01", date_to: "2025-02-28", transaction_type: "expense", sort: "desc") for all expenses
2. list_transactions(date_from: "2025-02-01", date_to: "2025-02-28", transaction_type: "income") for all income
3. list_budgets(month: "2025-02") for budget targets
4. list_accounts(active_only: true) for current account balances
