# stock_lh_yyb_control A read tool on the China Stock MCP Server MCP server. Agent View of the PolicyLayer registry record for `stock_lh_yyb_control`. HTML page: https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-lh-yyb-control ## Facts - Tool: `stock_lh_yyb_control` - 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_lh_yyb_control", "arguments": {} } } ``` ## Why stock_lh_yyb_control is rated Low Based on sibling tools being read-only market data queries (e.g., 'stock_a_all_pb', 'stock_a_high_low_statistics'), this tool likely retrieves Chinese stock data without modification capabilities. The absence of verbs like 'create', 'delete', 'execute', or 'update' in the name suggests data retrieval. However, confidence is moderate due to missing description and unclear meaning of 'yyb_control' suffix. From the tool's own definition: "Tool name 'stock_lh_yyb_control' appears to be a data retrieval function following the naming pattern of sibling tools (all prefixed with 'stock_' or 'news_'). No description provided, but context suggests stock market data query functionality." ## Use case AI agents call stock_lh_yyb_control 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_lh_yyb_control": {} } } ``` ## 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.
