ltspice-mcp Work in progress. Core functionality is usable but expect rough edges and breaking changes. An MCP server that connects LLM assistants (Claude, and any other MCP client) to real circuit simulation: LTspice and ngspice, plus direct editing of LTspice schematics. Simulation results come back as structured numbers — cutoff frequencies, overshoot, phase margin, rise times — so the assistant can design, verify, and iterate on circuits in the same files you open in LTspice. Built on spicelib. Quick start Install the server: Add it to your MCP client: Have LTspice or ngspice installed. Both are auto-detected on Windows, Linux, and macOS; on WSL the LTspice path must be set explicitly (WSL notes). Circuit editing works with no simulator at all. That's the setup. Python 3.13+ required. Verify with . Claude Desktop config lives at (macOS), (Windows), or (Linux). Cursor, Windsurf, Gemini CLI, Continue, Cline, Zed and others take the same JSON snippe

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
