StockMarketScan — Claude Code MCP server: 18 US equities tools
Wires screeners, chart patterns, options flow signals and market context for US stocks into your LLM client. Bring your own sms_* key and a paid plan.
claude mcp add --transport sse stockmarketscan https://mcp.stockmarketscan.com/mcpWhat StockMarketScan does
StockMarketScan is a remote MCP server at https://mcp.stockmarketscan.com/mcp speaking HTTP/SSE. It ships 18 tools grouped by purpose: three screeners (list_screeners, get_screener_data, search_stocks_in_screeners), two for chart patterns, four for options flow, two for stock info and candles, two composite ones (get_stock_report, search_setups), three for market context and one teaching tool (explain_concept). A ping tool handles liveness checks.
Auth is BYOK. The server keeps no key of its own; each client sends your personal sms_* value in the X-API-Key header. It validates that key once per session, then proxies tool calls to api/v1/* on your behalf. Rate limits and quota stay under your control, and you can rotate the key whenever you like in settings. A Basic or Pro plan is required, and the options flow tools only open up with the Options Flow add-on.
Limits differ by tier: Basic allows 15 requests per minute and 500 per day, Pro allows 30 per minute and 2,000 per day. A missing or expired key means the tools simply return nothing, so check that header first when the tool list looks empty. You can also run the server from source: npm install, then npm run dev for stdio or npm run dev:http for HTTP/SSE on port 3333.
What it helps with
- find tickers that show up in more than one screener
- review a stock's options flow history over the past month
- filter for stocks forming a specific chart pattern
- pull a single combined report on one ticker
- spot unusual options activity
Example prompts for the agent
- Which tickers are in both hot-prospects and golden-cross today?
- Build a full report on NVDA covering screeners, patterns, options flow and market context.
