WHAT IT DOES

What bittensor_forecast does on Swarmrails MCP

AI agents invoke bittensor_forecast to trigger actions in Swarmrails MCP. 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.

WHY IT NEEDS A POLICY

Why bittensor_forecast needs a policy

The tool executes a forecasting computation on an external subnet (Bittensor subnet 8) and incurs a $0.05 USDC charge per invocation. While it returns predictions (Read-like output), it actively triggers an external paid operation, making Execute the appropriate category.

From the tool's definition 'Financial and crypto time series forecasting via Bittensor subnet 8. Cost: $0.05 per call.' — triggers external computation on a Bittensor subnet with a per-call financial cost.
