lookup_error_code_tool
AI agents call lookup_error_code_tool to retrieve information from Qiskit Gym MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Lookup operations are typically Read operations that retrieve information without side effects. The empty description reduces confidence but does not change the likely classification. No evidence of destructive, financial, or code execution capabilities. In the context of a quantum circuit synthesis server, this would retrieve reference data.
From the tool's definition Tool name 'lookup_error_code_tool' indicates a retrieval/lookup operation. Description is empty, limiting ability to confirm exact behavior, but the name strongly suggests querying or retrieving error code information without modification.
Attacks that exploit this kind of access
lookup_error_code_tool. It is categorised as a Read tool in the Qiskit Gym MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Qiskit Gym MCP Server MCP server in PolicyLayer and add a rule for lookup_error_code_tool: 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 Qiskit Gym MCP Server. Nothing to install.
lookup_error_code_tool 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 lookup_error_code_tool 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 lookup_error_code_tool. 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.
lookup_error_code_tool is provided by the Qiskit Gym MCP Server MCP server (qiskit-gym-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
