The empty description prevents higher confidence, but naming convention and context strongly suggest read-only data retrieval with no side effects. No evidence of write, execute, delete, or financial transaction capabilities. From the tool's own definition: "Tool name 'stock_buffett_index_lg' with suffix '_lg' (consistent with sibling tools like 'stock_a_indicator_lg', 'stock_a_congestion_lg') indicates data retrieval. No destructive, financial transaction, or execution keywords present." ## Use case AI agents call stock_buffett_index_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_buffett_index_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.
