WHAT IT DOES

What transpile_circuit_tool does on Qiskit Gym MCP Server

AI agents invoke transpile_circuit_tool to trigger actions in Qiskit Gym MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why transpile_circuit_tool needs a policy

Transpiling a quantum circuit involves executing a compilation/transformation process that converts a circuit into a target hardware basis, which is an execution-class operation (running a transformation pipeline). The Qiskit context strongly implies this triggers computation. However, the description is empty, so confidence is reduced.

Verdict

transpile_circuit_tool Rate-limited

transpile_circuit_tool stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Qiskit Gym MCP Server, so you can run agents against it safely.

FAQ

Questions about transpile_circuit_tool

What does the transpile_circuit_tool tool do? +

transpile_circuit_tool. It is categorised as a Execute tool in the Qiskit Gym MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on transpile_circuit_tool? +

Register the Qiskit Gym MCP Server MCP server in PolicyLayer and add a rule for transpile_circuit_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.

What risk level is transpile_circuit_tool? +

transpile_circuit_tool is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit transpile_circuit_tool? +

Yes. Add a rate_limit block to the transpile_circuit_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.

How do I block transpile_circuit_tool completely? +

Set action: deny in the PolicyLayer policy for transpile_circuit_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.

What MCP server provides transpile_circuit_tool? +

transpile_circuit_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.
