List high-level circuit intent templates and default parameters.
AI agents call listIntentCircuitTemplates 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 performs a retrieval operation only—it queries and returns information about available circuit templates and their parameters. There are no side effects, no modifications to data, no code execution, and no destructive operations. This is a straightforward 'list/get' action, which falls clearly into the Read category with low severity due to its non-sensitive, informational nature.
From the tool's definition Tool name 'listIntentCircuitTemplates' and description 'List high-level circuit intent templates and default parameters' indicate a read-only query operation that retrieves and displays available templates without modifying data.
Documented attack patterns abuse exactly the kind of access listIntentCircuitTemplates 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 listIntentCircuitTemplates:
{
"version": "1",
"default": "deny",
"tools": {
"listIntentCircuitTemplates": {}
}
}listIntentCircuitTemplates 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.
List high-level circuit intent templates and default parameters. 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 listIntentCircuitTemplates: 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.
listIntentCircuitTemplates 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 listIntentCircuitTemplates 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 listIntentCircuitTemplates. 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.
listIntentCircuitTemplates 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.
Free to start. No card required.
