Attacks that exploit this kind of access
The rule that runs tengu_v3_factor_predictors safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Tengu, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For tengu_v3_factor_predictors, this is the rule to start with:
tengu_v3_factor_predictors stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Tengu, apply this rule, and every tengu_v3_factor_predictors call is checked against it from then on.
Questions about tengu_v3_factor_predictors
academic open-source predictor panel for one stock — a compact vector of 13 replicated accounting anomalies (Sloan accruals, Cooper-Gulen-Schill asset growth, Titman capital investment, Novy-Marx gross profitability, Fama-French operating profitability, cash-to-assets, leverage change, earnings consistency, revenue growth, positive-NI/positive-CFO flags, current ratio, net share issuance) at monthly grain. Call it for a ready-made feature vector when you don't need the full ~460-column factor panel. Returns the series newest-last, or with latest=true only the single most-recent row as a name->value map; with no start/end it serves the LATEST AVAILABLE rows (lagged quarterly archive) and reports the actual window. Ticker is resolved to its internal security key automatically (the table has no ticker column). It is categorised as a Execute tool in the Tengu MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
tengu_v3_factor_predictors accepts 5 parameters: end, limit, start, latest, ticker. Required: ticker. The full parameter table on this page comes from the server's own tool schema.
Register the Tengu MCP server in PolicyLayer and add a rule for tengu_v3_factor_predictors: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Tengu. Nothing to install.
tengu_v3_factor_predictors is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the tengu_v3_factor_predictors rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for tengu_v3_factor_predictors. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
tengu_v3_factor_predictors is provided by the Tengu MCP server (Hlobo-dev/tengu-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
