Get the current HikerAPI balance and request rate.
AI agents call get_system_balance to retrieve information from Instagram without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about API account balance and rate limits. It is a query operation with no side effects, no data modification, and no irreversible actions. It falls squarely into the Read category. Severity is low because exposing balance information poses minimal risk—an AI agent learning the current API quota cannot cause harm through this tool alone.
From the tool's definition Tool name 'get_system_balance' and description 'Get the current HikerAPI balance and request rate' indicate a read-only query operation that retrieves account or service status information without modifying any data.
Documented attack patterns abuse exactly the kind of access get_system_balance gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Instagram, and nothing reaches the server without passing your rules. This is the rule we recommend for get_system_balance:
{
"version": "1",
"default": "deny",
"tools": {
"get_system_balance": {}
}
}get_system_balance is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the current HikerAPI balance and request rate. It is categorised as a Read tool in the Instagram MCP Server, which means it retrieves data without modifying state.
Register the Instagram MCP server in PolicyLayer and add a rule for get_system_balance: 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 Instagram. Nothing to install.
get_system_balance 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 get_system_balance 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 get_system_balance. 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.
get_system_balance is provided by the Instagram MCP server (lupikovoleg/instagram-cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Instagram, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
