List LTspice plot names available in one RAW file or all RAW files from a run.
AI agents call getPlotNames 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 retrieves and lists plot names from simulation output files (RAW files). It performs a read-only query operation with no side effects—it does not create, modify, delete, or execute anything. The action is purely informational, returning metadata about available plots. This is a straightforward data retrieval operation fitting the 'Read' category.
From the tool's definition Tool name 'getPlotNames' and description 'List LTspice plot names available in one RAW file or all RAW files from a run' indicate retrieval/querying of metadata without modification or execution.
Documented attack patterns abuse exactly the kind of access getPlotNames 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 getPlotNames:
{
"version": "1",
"default": "deny",
"tools": {
"getPlotNames": {}
}
}getPlotNames is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List LTspice plot names available in one RAW file or all RAW files from a run. 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 getPlotNames: 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.
getPlotNames 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 getPlotNames 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 getPlotNames. 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.
getPlotNames 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.
