mx-select-stock（MX 选择股票）

妙想智能选股 Skill (mx_select_stock)

Overview

This skill enables safe, up‑to‑date stock screening using the Meixiang (妙想) stock‑screening service. It supports custom filters on market, financial indicators, and sector/category constraints, returning a full data table (CSV) with Chinese column headers and a supplemental description file.

Prerequisites

1. Obtain an API key from the Meixiang Skills page.
2. Export the key to the environment variable MX_APIKEY: export MX_APIKEY="your_api_key_here"
3. Ensure curl is installed (standard on macOS).

Usage Steps

1. Formulate the query – translate the user’s natural‑language request into a JSON payload containing at least:

- keyword – the screening condition (e.g., "今日涨幅2%的股票") - pageNo – page number (default 1) - pageSize – number of rows per page (max 100, adjust as needed)

1. Execute the POST request: curl -X POST \ --location 'https://mkapi2.dfcfs.com/finskillshub/api/claw/stock-screen' \ --header 'Content-Type: application/json' \ --header "apikey:${MX_APIKEY}" \ --data '{"keyword":"<YOUR_KEYWORD>","pageNo":1,"pageSize":20}'
2. Parse the JSON response – important fields:

- status / message – overall request success. - data.code / data.msg – business‑level status. - data.data.result.columns – column definitions. - data.data.result.dataList – rows of stock data. - responseConditionList – condition statistics.

1. Transform column titles – map each key to its Chinese title from the columns array, then build a CSV where the header line uses the Chinese titles.
2. Save output (optional): # Save raw JSON curl... > mx_select_stock_raw.json # Save CSV <script to convert> > mx_select_stock.csv # Save column description <script to extract> > mx_select_stock_columns.md
3. Present to the user – show a brief summary (total matches, key conditions) and attach the CSV/description files if the user requested them.

Example

User request: “筛选今日涨幅在 2% 以上的 A 股”。

Command:

curl -X POST --location 'https://mkapi2.dfcfs.com/finskillshub/api/claw/stock-screen' \
  --header 'Content-Type: application/json' \
  --header 'apikey:${MX_APIKEY}' \
  --data '{"keyword":"今日涨幅2%的股票","pageNo":1,"pageSize":20}'

Sample JSON excerpt (truncated):

{"status":0,"message":"ok","data":{"code":"100","msg":"解析成功","data":{"result":{"total":57,"columns":[{"title":"序号","key":"SERIAL"},{"title":"代码","key":"SECURITY_CODE"},{"title":"简称","key":"SECURITY_SHORT_NAME"},{"title":"市场","key":"MARKET_SHORT_NAME"},{"title":"最新价 (元)","key":"NEWEST_PRICE"},{"title":"涨跌幅 (%)","key":"CHG"}],"dataList":[{"SERIAL":"1","SECURITY_CODE":"603866","SECURITY_SHORT_NAME":"桃李面包","MARKET_SHORT_NAME":"SH","NEWEST_PRICE":12.34,"CHG":2.13}, ...]}}}}

Formatted reply to user:

• 匹配股票数量：57 只（符合条件）
• 筛选条件：今日涨幅 ≥ 2%
• 示例数据： 序号 代码 简称 市场 最新价 (元) 涨跌幅 (%) 1 603866 桃李面包 SH 12.34 2.13 2 300991 创益通 SZ 8.76 2.05

Saving Results (optional)

If the user wants the full CSV, run a conversion script (e.g., Python) that reads dataList, maps each key to its Chinese title, writes rows, and stores the file mx_select_stock.csv. Also generate mx_select_stock_columns.md describing each column.

When Not to Use

Do not invoke this skill for non‑financial queries, for generic web searches, or when the user explicitly asks for opinion‑based advice without needing raw screening data.
