Query the balance of a specific coin in a specific account type. Supports querying sub UID balance with master API key.\n-
AI agents call accountCoinBalanceQuery 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.
This tool retrieves account balance information (a read operation) with no side effects. It does not create, modify, delete, or execute any operations. While balance data is sensitive financial information, the tool itself performs only a read operation, and the risk is mitigated by requiring proper authentication to the account.
From the tool's definition Tool name "accountCoinBalanceQuery" and description "Query the balance of a specific coin" — the verb 'query' and 'Query' indicate data retrieval without modification.
Documented attack patterns abuse exactly the kind of access accountCoinBalanceQuery 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 accountCoinBalanceQuery:
{
"version": "1",
"default": "deny",
"tools": {
"accountCoinBalanceQuery": {}
}
}accountCoinBalanceQuery is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Query the balance of a specific coin in a specific account type. Supports querying sub UID balance with master API key.\n-. It is categorised as a Read tool in the Bybit MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Bybit MCP Server MCP server in PolicyLayer and add a rule for accountCoinBalanceQuery: 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.
accountCoinBalanceQuery is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the accountCoinBalanceQuery 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 accountCoinBalanceQuery. 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.
accountCoinBalanceQuery is provided by the Bybit MCP Server MCP server (bybit-exchange/trading-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Bybit MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
