LTspice Waveform Plot MCP App

MCP App · UI in chat

from"Cognitohazard"

Cognitohazard/ltspice-mcp gives agents SPICE design, simulation and analysis tools. Its analysis tool metadata points to an MCP Apps waveform resource, allowing supported hosts to render interactive trace plots.

Not for: Replacing engineering verification, component limits or lab measurement. Simulations depend on model quality, solver settings and the installed simulator.

>Questions

Is LTspice Waveform Plot MCP App an MCP App with inline UI?

Yes. The maintainer's source declares an MCP UI resource and links it to a tool result. It renders inline only in hosts that support MCP Apps.

Where were these details checked?

Against the maintainer's README, source, or official documentation at https://github.com/Cognitohazard/ltspice-mcp, plus the GitHub API where a repository is available.
