AI agents call get_quota to retrieve information from Vimax without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves current quota usage data. It performs a read-only operation that returns information about resource consumption with no capability to modify, delete, or execute external operations. The low severity reflects that misuse would only expose usage information, not enable unauthorized actions or resource consumption.
From the tool's definition Tool name 'get_quota' and description 'Today's daily quota usage for chat / image / video providers (UTC day)' indicate retrieval of quota information without modification or side effects.
Attacks that exploit this kind of access
Today's daily quota usage for chat / image / video providers (UTC day). It is categorised as a Read tool in the Vimax MCP Server, which means it retrieves data without modifying state.
Register the Vimax MCP server in PolicyLayer and add a rule for get_quota: 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 Vimax. Nothing to install.
get_quota 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_quota 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_quota. 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_quota is provided by the Vimax MCP server (zcdeng/vimax-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
