adjust_leverage · Mcp Pear MCP: Risk & Policy

WHAT IT DOES

What adjust_leverage does on Mcp Pear

AI agents use adjust_leverage 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 adjust_leverage needs a policy

adjust_leverage modifies the leverage multiplier on an existing position, which changes the position's risk exposure and margin requirements. This is a reversible modification (leverage can be adjusted again), not an irreversible deletion. While it operates on financial positions, it does not move money or create new financial obligations—it adjusts the parameters of an existing position.

From the tool's definition Tool description explicitly states 'WRITE: changes risk profile of a live position' and 'Change leverage (1-100x) on an existing Pear Protocol position.' This modifies an active financial position's parameters reversibly.

Verdict

adjust_leverage Rate-limited

adjust_leverage stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
