# tengu_v3_supply_chain_relationships

The SUPPLY-CHAIN GRAPH around one company — its customers, suppliers, competitors and partners in one call, each with the relationship's start date, whether it is still open, which side reported it, and revenue dependence where it was estimated. Both directions are merged and normalised to the queried company's point of view, so 'customers' includes companies that report THIS company as their supplier. Call it to map second-order exposure (whose earnings move when this name moves) or to find the listed suppliers behind a product cycle. Defaults to CURRENT relationships; status=all or as_of=YYYY-MM-DD gives history. One entry per counterparty by default (several records can back one pair) — group_by=record gives the underlying versions. revenue_percent belongs to the company named in revenue_percent_of_ticker, is an ESTIMATE on every row, and is present on only a minority of edges; coverage is reported per group.

## Why tengu_v3_supply_chain_relationships is rated High

tengu_v3_supply_chain_relationships triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

## Use case

AI agents invoke tengu_v3_supply_chain_relationships to trigger actions in Tengu. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Tengu:
