WHAT IT DOES

What getWalletBalance does on Bybit MCP Server

AI agents call getWalletBalance 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 RISK

Low Risk

Why getWalletBalance needs a policy

This tool queries and retrieves wallet balance and asset information from the Bybit exchange. It performs no mutations, transactions, or state changes—merely fetching account balance data. While the Bybit context involves financial data, the tool itself is a read-only query operation that does not move money, execute trades, or modify any account state.

From the tool's definition Tool name 'getWalletBalance' and description 'Obtain wallet balance, query asset information' indicate a data retrieval operation with no side effects or modifications.

POLICY

How to control getWalletBalance

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 getWalletBalance:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "getWalletBalance": {}
  }
}

getWalletBalance is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
