Summarize ScreenCapture/LTspice capture health from in-process capture events.
AI agents call getCaptureHealth 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 reports on the health status of capture-related processes without modifying, executing external operations, deleting, or committing financial transactions. It is purely informational—summarizing existing capture events and their state. The blast radius of misuse is minimal as it only exposes diagnostic telemetry.
From the tool's definition Tool name 'getCaptureHealth' and description 'Summarize ScreenCapture/LTspice capture health from in-process capture events' indicate retrieval and summarization of diagnostic/status information about screen capture processes.
Documented attack patterns abuse exactly the kind of access getCaptureHealth 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 getCaptureHealth:
{
"version": "1",
"default": "deny",
"tools": {
"getCaptureHealth": {}
}
}getCaptureHealth is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Summarize ScreenCapture/LTspice capture health from in-process capture events. 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 getCaptureHealth: 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.
getCaptureHealth 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 getCaptureHealth 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 getCaptureHealth. 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.
getCaptureHealth 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.
