What set_risk_parameters does on Mcp Pear

AI agents use set_risk_parameters to create or update resources in Mcp Pear — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Pear environment.

WHY IT NEEDS A POLICY

Why set_risk_parameters needs a policy

This tool creates or modifies risk parameters (stop-loss and take-profit thresholds) on trading positions, which is a reversible configuration change. While it does not directly execute trades or move capital, it alters position parameters that govern automated trading behavior. Classified as Write rather than Execute because it updates configuration rather than triggering immediate external operations.

From the tool's definition Tool name 'set_risk_parameters' and description 'Set or update stop-loss / take-profit on an existing Pear Protocol position' indicate modification of position parameters. The verb 'Set or update' confirms write operation.
