What active_instance_info_tool does on Qiskit IBM Transpiler MCP Server
AI agents call active_instance_info_tool to retrieve information from Qiskit IBM Transpiler MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why active_instance_info_tool is rated Low
This tool only retrieves and returns information about the current instance configuration (its CRN identifier). It performs no side effects, data modification, code execution, or destructive actions. The severity is low because disclosure of a CRN is informational and does not grant unauthorized access by itself; it is the type of metadata typically needed for normal API operations.
From the tool's definition Tool description states 'Get the Cloud Resource Name (CRN) of the currently active instance' — a retrieval operation that queries metadata about the active instance without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
The rule that runs active_instance_info_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 active_instance_info_tool, this is the rule to start with:
active_instance_info_tool is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Qiskit IBM Transpiler MCP Server, apply this rule, and every active_instance_info_tool call is checked against it from then on.
Questions about active_instance_info_tool
Get the Cloud Resource Name (CRN) of the currently active instance. It is categorised as a Read tool in the Qiskit IBM Transpiler MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Qiskit IBM Transpiler MCP Server MCP server in PolicyLayer and add a rule for active_instance_info_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.
active_instance_info_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 active_instance_info_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 active_instance_info_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.
active_instance_info_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.
