AI agents call queryFixedBorrowContracts 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.

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 queryFixedBorrowContracts:
{
"version": "1",
"default": "deny",
"tools": {
"queryFixedBorrowContracts": {}
}
}queryFixedBorrowContracts is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
