About this plugin
Financial market data has been a blind spot for AI agents. market-watch closes that gap: it lets any dsh agent query the latest quotes for A-share stocks, Shanghai/Shenzhen/Beijing indices, and major cryptocurrencies directly, powered by Tencent free quote endpoints and the CoinGecko public API, with no browser or paid plan required.
Beyond point-in-time lookups, it watches for you. A locally persisted watchlist, threshold alert rules (changePercent or price with gt/gte/lt/lte operators) evaluated on every poll tick, cooldown windows to prevent spam, and best-effort delivery into live agent sessions via harness events. In-chat ASCII column charts, sparklines, and Mermaid xychart blocks render a thirty-day trend at a glance.
Built for: developers adding financial awareness to their agents, quant hobbyists who want desk-side price alerts, and anyone who would rather sketch a chart in conversation than fire up TradingView.
Use Cases
- Query latest A-share index and crypto quotes directly in chat
- Set price threshold alerts and let the agent watch and notify
- Render an ASCII trend chart in conversation without opening a trading app
Best For
- Developers adding financial awareness to their dsh agents
- Quant hobbyists who want desktop-grade price alerts
- Everyday users who prefer sketching a chart in chat over switching apps
