stock-mcp
MCP server that syncs and queries comprehensive stock data (quotes, financials, dividends, analyst forecasts, options, news) from Yahoo Finance and Investing.com into an external MySQL database.
README
stock-mcp
MCP server(TypeScript / Node.js)通过 Yahoo Finance 和 Investing.com(GraphQL + TVC) 获取股票全量信息,持久化到 外部 MySQL(通过 DATABASE_URL 连接串配置,不随 server 内置),按标的代码查询。
架构上 MCP server 保持轻量:它只是一个薄查询层 + 同步触发器,数据库是完全外部的依赖。
快速开始
npm install
npm run build:all # TypeScript + Go sidecar
# 0. 配置外部 MySQL 连接(.env)
# DATABASE_URL=mysql://user:pass@host:3306/stock_mcp
# 本地临时开发库可用 deploy/docker-compose.mysql.yml 起一个:
# docker compose -f deploy/docker-compose.mysql.yml up -d
# 1. 对配置的数据库初始化表结构
npm run db:init
# 2. 全量同步一只股票(从 2000-01-01 开始拉历史 + 全部基本面)
npm run sync -- --symbol NVDA --full
# 之后增量同步(只拉新增数据)
npm run sync -- --symbol NVDA
# 同步所有已入库标的
npm run sync -- --all --full
# 3. 启动 MCP server(stdio)
npm run server

数据源
- Yahoo Finance:K 线(v8 chart)、quoteSummary(需 cookie+crumb)、期权(v7)、新闻(v1 search)、财务(fundamentals-timeseries,免认证)
- Investing.com:GraphQL
gql.api.investing.com/graphql(行情/三表/比率/分红/预测/盈利/公司资料/高管/持有人,免认证)、TVC K 线(carrier token)
客户端接入示例(Claude Desktop / Cursor / Codex)
{
"mcpServers": {
"stock-mcp": {
"command": "node",
"args": ["/path/to/stock-mcp/dist/cli.js", "server"]
}
}
}
说明
- 全量同步:从
BARS_START_DATE(默认 2000-01-01)拉全部日 K + 全部基本面 + 期权快照 + 新闻。 - 增量同步:按
sync_state.last_bar_date只拉新 K 线,并刷新行情、比率、预测、新闻、期权快照。 - 所有写入均为幂等 upsert(
INSERT ... ON DUPLICATE KEY UPDATE),可重复执行。 - 限流已内置(默认 300ms/请求),Yahoo crumb 缓存 25 分钟,TVC token 缓存 25 分钟。
关于 investing.com 的 TLS 拦截
investing.com 通过 Cloudflare TLS 指纹拦截 Node.js 的请求(HTTP 403),Go 客户端可正常访问。因此项目内置了一个极小的 Go 传输代理 cmd/gqlproxy(约 200 行,仅标准库):
npm run build:sidecar # 生成 bin/gqlproxy
TS 数据源层默认先试 Node fetch,遇到 403 自动切换到该代理(含持久化 cookie 会话,自动处理 Cloudflare challenge)。从不受指纹拦截的网络访问时无需代理,可设置 INVESTING_TRANSPORT=node 强制纯 Node。
# 完整构建(TypeScript + Go sidecar)
npm run build:all
