HTML page: https://policylayer.com/tools/peikuo-china-stock-mcp-server/stock-index-pb-lg ## Facts - Tool: `stock_index_pb_lg` - 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_index_pb_lg", "arguments": {} } } ``` ## Why stock_index_pb_lg is rated Low This tool appears to retrieve stock index data without modifying, deleting, or executing operations. The lack of verbs suggesting mutation (create, update, delete, execute) and its position among other read-only financial data tools on this MCP server indicate it is a simple Read operation. Confidence is moderate (0.8) because the description is empty, requiring inference from naming conventions and sibling tools. From the tool's own definition: "Tool name 'stock_index_pb_lg' suggests retrieval of stock index price-to-book ratio data (pb = price-to-book, lg likely indicating large-cap or a data grouping)." ## Use case AI agents call stock_index_pb_lg 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_index_pb_lg": {} } } ``` ## 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.
