Get all CDF properties of a specific instance.
AI agents call virtuoso_get_instance_properties to retrieve information from Virtuoso Schematic MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns data about instance properties without creating, modifying, deleting, or executing any operations. It is purely informational, used to inspect schematic component metadata. The blast radius if misused by an agent is minimal: at worst, information disclosure about the design, but no structural changes to schematics or external effects.
From the tool's definition Tool retrieves 'all CDF properties of a specific instance' — a read-only inspection operation with no modification, deletion, or code execution.
Attacks that exploit this kind of access
Get all CDF properties of a specific instance. It is categorised as a Read tool in the Virtuoso Schematic MCP MCP Server, which means it retrieves data without modifying state.
Register the Virtuoso Schematic MCP server in PolicyLayer and add a rule for virtuoso_get_instance_properties: 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 Virtuoso Schematic MCP. Nothing to install.
virtuoso_get_instance_properties 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 virtuoso_get_instance_properties 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 virtuoso_get_instance_properties. 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.
virtuoso_get_instance_properties is provided by the Virtuoso Schematic MCP server (michelebergo/virtuoso-schematic-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
