# stock_us_daily Get historical daily data for a specific US stock. Agent View of the PolicyLayer registry record for `stock_us_daily`. HTML page: https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-us-daily ## Facts - Tool: `stock_us_daily` - Server: China Stock MCP Server (`peikuo/china-stock-mcp-server`) — https://policylayer.com/tools/peikuo-china-stock-mcp-server.md - Homepage: https://github.com/peikuo/china-stock-mcp-server - Risk category: Read (Low risk) - Registry record: grade C, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "stock_us_daily", "arguments": {} } } ``` ## Why stock_us_daily is rated Low The tool performs a data retrieval operation on historical stock price information. It queries an external API (AKShare) to fetch read-only market data. There are no indications of write, delete, execution, or financial transaction capabilities. The blast radius of misuse is minimal—an agent could only retrieve historical data that is publicly available. From the tool's own definition: "Tool name is 'stock_us_daily' and description states 'Get historical daily data for a specific US stock' — this retrieves data with no modification or side effects." ## Use case AI agents call stock_us_daily to retrieve information from China Stock MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches China Stock MCP Server: ```json { "version": "1", "default": "deny", "tools": { "stock_us_daily": {} } } ``` ## Other tools on China Stock MCP Server (350) - `news_report_time_baidu` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/news-report-time-baidu.md - `news_trade_notify_dividend_baidu` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/news-trade-notify-dividend-baidu.md - `news_trade_notify_suspend_baidu` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/news-trade-notify-suspend-baidu.md - `stock_a_all_pb` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-a-all-pb.md - `stock_a_below_net_asset_statistics` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-a-below-net-asset-statistics.md - `stock_a_congestion_lg` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-a-congestion-lg.md - `stock_a_gxl_lg` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-a-gxl-lg.md - `stock_a_high_low_statistics` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-a-high-low-statistics.md - `stock_a_indicator_lg` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-a-indicator-lg.md - `stock_a_ttm_lyr` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-a-ttm-lyr.md - `stock_account_statistics_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-account-statistics-em.md - `stock_add_stock` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-add-stock.md - `stock_allotment_cninfo` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-allotment-cninfo.md - `stock_analyst_detail_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-analyst-detail-em.md - `stock_analyst_rank_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-analyst-rank-em.md - `stock_balance_sheet_by_report_delisted_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-balance-sheet-by-report-delisted-em.md - `stock_balance_sheet_by_report_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-balance-sheet-by-report-em.md - `stock_balance_sheet_by_yearly_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-balance-sheet-by-yearly-em.md - `stock_bid_ask_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-bid-ask-em.md - `stock_bj_a_spot_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-bj-a-spot-em.md - `stock_board_change_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-board-change-em.md - `stock_board_concept_cons_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-board-concept-cons-em.md - `stock_board_concept_hist_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-board-concept-hist-em.md - `stock_board_concept_hist_min_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-board-concept-hist-min-em.md - `stock_board_concept_index_ths` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-board-concept-index-ths.md - `stock_board_concept_info_ths` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-board-concept-info-ths.md - `stock_board_concept_name_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-board-concept-name-em.md - `stock_board_concept_spot_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-board-concept-spot-em.md - `stock_board_industry_cons_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-board-industry-cons-em.md - `stock_board_industry_hist_em` — Read — https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-board-industry-hist-em.md - …and 320 more: https://policylayer.com/tools/peikuo-china-stock-mcp-server.md ## For agents This record is a snapshot.
