What switch_position_mode does on Bybit MCP Server
AI agents use switch_position_mode to create or update resources in Bybit MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Bybit MCP Server environment.
Why switch_position_mode is rated Medium
This tool modifies account settings that directly impact trading strategy execution and position management. While it doesn't execute trades itself, switching position modes alters the account state and can affect how subsequent trades behave. It is reversible (can switch back), so it is Write rather than Execute or Destructive.
From the tool's definition 'Switch between one-way mode (net position) and hedge mode (separate long/short positions)' — this modifies account configuration that changes how positions are managed and affects position entry/exit behavior.
Attacks that exploit this kind of access
The rule that runs switch_position_mode safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Bybit MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For switch_position_mode, this is the rule to start with:
switch_position_mode 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Bybit MCP Server, apply this rule, and every switch_position_mode call is checked against it from then on.

Register the Bybit MCP Server MCP server in PolicyLayer and add a rule for switch_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 Bybit MCP Server. Nothing to install.
switch_position_mode is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the switch_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.
Set action: deny in the PolicyLayer policy for switch_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.
switch_position_mode is provided by the Bybit MCP Server MCP server (bcusack/bybit-py-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
