Scan LTspice log text for missing model/include/subcircuit issues.
AI agents call scanModelIssues to retrieve information from Ltspice without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool analyzes existing log data and reports findings without altering state, executing code, or triggering side effects. It is a diagnostic utility that reads and interprets text to help users understand simulation issues.
From the tool's definition Tool performs a 'scan' operation on LTspice log text to identify 'missing model/include/subcircuit issues' — a purely analytical/diagnostic read operation with no modification, deletion, or execution of external commands.
Documented attack patterns abuse exactly the kind of access scanModelIssues gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ltspice, and nothing reaches the server without passing your rules. This is the rule we recommend for scanModelIssues:
{
"version": "1",
"default": "deny",
"tools": {
"scanModelIssues": {}
}
}scanModelIssues is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Scan LTspice log text for missing model/include/subcircuit issues. It is categorised as a Read tool in the Ltspice MCP Server, which means it retrieves data without modifying state.
Register the Ltspice MCP server in PolicyLayer and add a rule for scanModelIssues: 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 Ltspice. Nothing to install.
scanModelIssues 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 scanModelIssues 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 scanModelIssues. 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.
scanModelIssues is provided by the Ltspice MCP server (xuio/ltspice-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Ltspice, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
