dsh-duizhang: Financial Data Processing and Reconciliation Toolkit

`dsh-duizhang` is a plugin in DeepSeek Harness dedicated to financial data automation and maintained by the ainetcafe.com team. It provides 15 tools via the MCP protocol, covering core financial workflows such as document parsing, spreadsheet cleaning, reconciliation and consolidating, and tax calculation. The plugin can handle the extraction and conversion of bank statements and invoices, supports matching transactions and ledgers by amount and date without shared keys, and can validate Unified Social Credit Codes and calculate VAT. Its runtime environment requires no local code, data processing is performed in memory, and permissions are limited to outbound network access. It can be invoked through natural language, aiming to lower the barrier to financial automation and provide developers with a ready-to-implement solution.
