List all nets (connections) in a cellview.
AI agents call virtuoso_get_nets 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.
The tool retrieves and enumerates net connections within a circuit design (cellview) for inspection purposes. This is a non-destructive read operation with no side effects on the design data. The blast radius is minimal — an agent accessing net lists cannot cause irreversible changes, execute arbitrary code, or compromise the design integrity.
From the tool's definition Tool description states 'List all nets (connections) in a cellview' — a query operation that retrieves schematic connectivity information without modification or execution.
Attacks that exploit this kind of access
List all nets (connections) in a cellview. 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_nets: 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_nets 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_nets 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_nets. 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_nets 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.
