# tengu_v3_features_dataset READ ONE DERIVED FEATURE PANEL — the model-ready research features this platform computes for itself: price/return and liquidity features, monthly fundamentals, analyst-estimate dynamics, options and volatility-surface features, insider and institutional-ownership features, news-sentiment features, betas, regime and macro features. Discover the slugs via /api/v3/features/datasets — they are product names, not table names. With ?ticker= you get that symbol's observations newest first; without it you get the LATEST cross-section (every symbol on the most recent observation date), which is bounded by construction rather than by sorting the whole panel. Symbols resolve through the shared security resolver first and identity.identity_verified states whether the read was keyed on an authoritative identifier or on the resolved security's symbol; an ambiguous symbol is refused, never guessed. Every response carries the dataset's measured coverage (rows_total, symbols_total, observation_dates, history window) and its freshness, so an empty rows array arrives beside the count of symbols that DO have rows and can never be read as a dead upstream — result is the machine-readable outcome (rows, no_rows_for_symbol, no_rows_in_window). Five of the 19 servable datasets are archival: their producer has stopped, they are served for their history, and every response says so rather than implying currency. An unknown or withheld slug is a 404 and an unreadable store is a 503 — both refunded, because a billed 200 over an empty array is the defect this endpoint exists to remove.

HTML page: https://policylayer.com/tools/tengu-mcp/tengu-v3-features-dataset ## Facts - Tool: `tengu_v3_features_dataset` - Server: Tengu (`Hlobo-dev/tengu-mcp`) — https://policylayer.com/tools/tengu-mcp.md - Homepage: https://github.com/Hlobo-dev/tengu-mcp - Risk category: Destructive (Critical risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server rate-limited: no - Parameters: 5 (1 required) - Recommended policy verdict: Hidden ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `limit` | integer | no | | | `since` | string | no | | | `until` | string | no | | | `ticker` | string | no | | | `dataset` | string | yes | Path parameter 'dataset' (required). | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "tengu_v3_features_dataset", "arguments": { "dataset": "" } } } ``` ## Why tengu_v3_features_dataset is rated Critical An AI agent that decides to call tengu_v3_features_dataset doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Tengu is gone. There is no undo for destructive operations. Risk signals: Bulk/mass operation — affects multiple targets ## Use case AI agents call tengu_v3_features_dataset to permanently remove resources in Tengu, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo. ## Recommended policy (PolicyLayer) Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Tengu: ```json { "version": "1", "default": "deny", "hide": [ "tengu_v3_features_dataset" ] } ``` ## Other tools on Tengu (336) - `tengu_v3_intel_borrow_cost_history` — Destructive — https://policylayer.com/tools/tengu-mcp/tengu-v3-intel-borrow-cost-history.md - `tengu_v3_intel_insider_flow` — Destructive — https://policylayer.com/tools/tengu-mcp/tengu-v3-intel-insider-flow.md - `tengu_v3_intel_risk_free_rate` — Destructive — https://policylayer.com/tools/tengu-mcp/tengu-v3-intel-risk-free-rate.md - `tengu_v3_intel_sec13f_changes` — Destructive — https://policylayer.com/tools/tengu-mcp/tengu-v3-intel-sec13f-changes.md - `tengu_v3_backtest_run_detail` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-backtest-run-detail.md - `tengu_v3_briefing_daily` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-briefing-daily.md - `tengu_v3_factor_predictors` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-factor-predictors.md - `tengu_v3_intel_darkpool_history` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-intel-darkpool-history.md - `tengu_v3_intel_gex_history` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-intel-gex-history.md - `tengu_v3_intel_ml_drivers` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-intel-ml-drivers.md - `tengu_v3_intel_ml_prediction` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-intel-ml-prediction.md - `tengu_v3_intel_options_flow_history` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-intel-options-flow-history.md - `tengu_v3_news_sentiment_history` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-news-sentiment-history.md - `tengu_v3_optimizer_latest` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-optimizer-latest.md - `tengu_v3_prices_corporate_actions` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-prices-corporate-actions.md - `tengu_v3_private_markets_service_provider_relations` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-private-markets-service-provider-relations.md - `tengu_v3_reference_coverage` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-reference-coverage.md - `tengu_v3_supply_chain_relationships` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-supply-chain-relationships.md - `tengu_v3_tape_bars` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-tape-bars.md - `tengu_v3_validation_trials` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-validation-trials.md - `tengu_v3_workforce_layoffs` — Execute — https://policylayer.com/tools/tengu-mcp/tengu-v3-workforce-layoffs.md - `tengu_cache_stats` — Read — https://policylayer.com/tools/tengu-mcp/tengu-cache-stats.md - `tengu_copilot_decision_review` — Read — https://policylayer.com/tools/tengu-mcp/tengu-copilot-decision-review.md - `tengu_copilot_live_ic_drift` — Read — https://policylayer.com/tools/tengu-mcp/tengu-copilot-live-ic-drift.md - `tengu_copilot_macro_regime` — Read — https://policylayer.com/tools/tengu-mcp/tengu-copilot-macro-regime.md - `tengu_copilot_score_ticker` — Read — https://policylayer.com/tools/tengu-mcp/tengu-copilot-score-ticker.md - `tengu_copilot_signal_health` — Read — https://policylayer.com/tools/tengu-mcp/tengu-copilot-signal-health.md - `tengu_copilot_ticker_full` — Read — https://policylayer.com/tools/tengu-mcp/tengu-copilot-ticker-full.md - `tengu_copilot_ticker_smartmoney` — Read — https://policylayer.com/tools/tengu-mcp/tengu-copilot-ticker-smartmoney.md - `tengu_copilot_ticker_transparency` — Read — https://policylayer.com/tools/tengu-mcp/tengu-copilot-ticker-transparency.md - …and 306 more: https://policylayer.com/tools/tengu-mcp.md ## For agents This record is a snapshot.
