WHAT IT DOES

What run_estimator_tool does on Qiskit IBM Transpiler MCP Server

AI agents invoke run_estimator_tool to trigger actions in Qiskit IBM Transpiler 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.

RISK

Why run_estimator_tool is rated High

The tool appears to execute quantum estimation operations rather than merely read or write data. While the description is empty, the name combined with the context of a Qiskit transpiler server (which compiles quantum circuits) and sibling tools that suggest quantum circuit execution suggests this tool runs code/computations.

From the tool's definition Tool name 'run_estimator_tool' indicates execution of an estimator (likely a quantum circuit estimator in the Qiskit context).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs run_estimator_tool safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Qiskit IBM Transpiler MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For run_estimator_tool, this is the rule to start with:

run_estimator_tool Rate-limited

run_estimator_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.

FAQ

Questions about run_estimator_tool

What does the run_estimator_tool tool do? +

run_estimator_tool is a execute tool on the Qiskit IBM Transpiler MCP Server MCP server. It is categorised as a Execute tool in the Qiskit IBM Transpiler 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 run_estimator_tool? +

Register the Qiskit IBM Transpiler MCP Server MCP server in PolicyLayer and add a rule for run_estimator_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 IBM Transpiler MCP Server. Nothing to install.

What risk level is run_estimator_tool? +

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

Can I rate-limit run_estimator_tool? +

Yes. Add a rate_limit block to the run_estimator_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 run_estimator_tool completely? +

Set action: deny in the PolicyLayer policy for run_estimator_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 run_estimator_tool? +

run_estimator_tool is provided by the Qiskit IBM Transpiler MCP Server MCP server (qiskit-ibm-transpiler-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
