virtuoso_create_wire · Virtuoso Schematic MCP: Risk & Policy

WHAT IT DOES

What virtuoso_create_wire does on Virtuoso Schematic MCP

AI agents use virtuoso_create_wire to create or update resources in Virtuoso Schematic MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Virtuoso Schematic MCP environment.

WHY IT NEEDS A POLICY

Why virtuoso_create_wire needs a policy

Creating a wire modifies the schematic by adding a net connection between points. This is a reversible operation (wires can be deleted) and falls under Write category. Severity is medium because misconfiguration could introduce incorrect electrical connections affecting circuit behavior, requiring design review to fix, but the change itself is not destructive or financial in nature.

From the tool's definition Tool description explicitly states 'Create a wire (net connection) in a schematic' — this creates a new connection in the design, modifying the schematic structure reversibly.

Verdict

virtuoso_create_wire Rate-limited

virtuoso_create_wire stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about virtuoso_create_wire

What does the virtuoso_create_wire tool do? +

Create a wire (net connection) in a schematic between specified points. It is categorised as a Write tool in the Virtuoso Schematic MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on virtuoso_create_wire? +

Register the Virtuoso Schematic MCP server in PolicyLayer and add a rule for virtuoso_create_wire: 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.

What risk level is virtuoso_create_wire? +

virtuoso_create_wire is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit virtuoso_create_wire? +

Yes. Add a rate_limit block to the virtuoso_create_wire 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 virtuoso_create_wire completely? +

Set action: deny in the PolicyLayer policy for virtuoso_create_wire. 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 virtuoso_create_wire? +

virtuoso_create_wire 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.
