dsh-quant-data-mcp: Zero-Dependency MCP stdio Server Template and A-Share Data Examples

dsh-quant-data-mcp is a zero-dependency, keyless general-purpose template and ready-to-use example for A-share data, designed specifically for DeepSeek Harness (DSH). The tool utilizes only Node.js built-in modules, requiring no third-party dependencies or build steps, and is configured via environment variables while strictly adhering to the MCP official NDJSON frame format. Core features include providing six A-share data tools (such as daily data, snapshots, financial data, and northbound funds), supporting automatic fallback between East Money and Tencent data sources, and enabling logging via environment variables. The runtime requires Node.js >= 18 and DSH version v0.1.0-rc.6 or higher. Installation is supported on Windows PowerShell.
