Get the Cloud Resource Name (CRN) of the currently active instance.
AI agents call active_instance_info_tool to retrieve information from Qiskit Documentation 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 information about the currently active instance (its CRN identifier). It is a straightforward read operation with no side effects. The worst-case misuse would be an agent learning which instance is active, which poses minimal risk. No data is created, modified, deleted, or executed.
From the tool's definition Tool name 'active_instance_info_tool' and description 'Get the Cloud Resource Name (CRN) of the currently active instance' indicate a query operation that retrieves metadata about the current instance without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
Get the Cloud Resource Name (CRN) of the currently active instance. It is categorised as a Read tool in the Qiskit Documentation MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Qiskit Documentation 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 Documentation 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 Documentation MCP Server MCP server (pypi:qiskit-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
