change_position_mode · Bitunix MCP: Risk & Policy

WHAT IT DOES

What change_position_mode does on Bitunix MCP

AI agents invoke change_position_mode to trigger actions in Bitunix 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 change_position_mode needs a policy

Changing position mode alters how the exchange handles open positions and orders (one-way vs hedge). This is an operational configuration change that triggers external state changes on the exchange, affecting how trades are executed and managed. It doesn't directly move money but can significantly impact open positions and risk exposure.

change_position_mode Rate-limited

change_position_mode stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

How do I enforce a policy on change_position_mode? +

Register the Bitunix MCP server in PolicyLayer and add a rule for change_position_mode: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Bitunix MCP. Nothing to install.

What risk level is change_position_mode? +

change_position_mode is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit change_position_mode? +

Yes. Add a rate_limit block to the change_position_mode rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block change_position_mode completely? +

Set action: deny in the PolicyLayer policy for change_position_mode. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides change_position_mode? +

change_position_mode is provided by the Bitunix MCP server (luiinventions/bitunix-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
