Show this API key
AI agents call usage to retrieve information from Parallelix without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays API key usage or quota information. While API keys are sensitive, the tool itself performs a read-only operation with no side effects, no code execution, and no data modification. The low severity reflects that viewing key details is less critical than exposing the ability to *use* that key for unauthorized operations.
From the tool's definition Tool name 'usage' with description 'Show this API key' indicates retrieval/display of API key information without modification or execution of compute tasks.
Attacks that exploit this kind of access
Show this API key. It is categorised as a Read tool in the Parallelix MCP Server, which means it retrieves data without modifying state.
Register the Parallelix MCP server in PolicyLayer and add a rule for usage: 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 Parallelix. Nothing to install.
usage 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 usage 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 usage. 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.
usage is provided by the Parallelix MCP server (parallelixnetwork/parallelix-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
