modify_order · HyperLiquid MCP Server MCP: Risk & Policy

WHAT IT DOES

What modify_order does on HyperLiquid MCP Server

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

WHY IT NEEDS A POLICY

Why modify_order needs a policy

An AI agent can call modify_order faster than any human can review — one bad instruction and it creates or modifies resources in HyperLiquid MCP Server by the hundred, each call as confident as the last.

Verdict

modify_order Rate-limited

modify_order 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.
