AI agents call getClosePosition to retrieve information from Bybit MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves read-only information about past trading positions. The word 'Query' and absence of any write, execute, delete, or financial action verbs confirms this is a Read operation. While the server overall permits trading and financial transactions, this specific tool only retrieves historical data.
From the tool's definition Tool name 'getClosePosition' and description 'Query closed option position data' — this is a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access getClosePosition gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Bybit MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for getClosePosition:
{
"version": "1",
"default": "deny",
"tools": {
"getClosePosition": {}
}
}getClosePosition is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
