get_fake_backend_coupling_map_tool
AI agents call get_fake_backend_coupling_map_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.
This tool retrieves a coupling map from a fake (simulated) quantum backend—a data structure describing qubit connectivity. No parameters are evident that would enable modification, deletion, or execution of arbitrary code. It appears to be a simple getter for static or pre-computed configuration data used in quantum circuit synthesis workflows.
From the tool's definition Tool name 'get_fake_backend_coupling_map_tool' indicates retrieval of a fake backend's coupling map data. The 'get' prefix and absence of modification keywords suggest a read-only query operation. Description is empty, limiting confidence.
Attacks that exploit this kind of access
get_fake_backend_coupling_map_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 get_fake_backend_coupling_map_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.
get_fake_backend_coupling_map_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 get_fake_backend_coupling_map_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 get_fake_backend_coupling_map_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.
get_fake_backend_coupling_map_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.
