ltspice-mcp vs Figma-Context-MCP

ltspice-mcp: This project provides an MCP server that bridges LLM assistants with powerful circuit simulators like LTspice and ngspice, along with direct editing capabilities for LTspice schematics. It allows AI assistants to design, verify, and iterate on circuits by interpreting simulation results as structured data and interacting with circuit files directly, avoiding manual rawfile parsing.; Figma-Context-MCP: This project provides a Model Context Protocol (MCP) server that grants AI-powered coding tools like Cursor direct access to Figma design data. It enables one-shot implementation of designs in any framework by simplifying and optimizing Figma API responses for AI models.

Features

ltspice-mcp logoltspice-mcp
01Simulation and structured measurement results: Runs LTspice/ngspice, parses binary output directly, and returns precise measurements (e.g., cutoff frequencies, operating points, stability margins) as structured numbers.
02Schematic and netlist editing: Supports creation and modification of LTspice `.asc` schematics and SPICE `.cir`/`.net` netlists with built-in validation.
03Advanced analysis capabilities: Enables multi-dimensional parameter sweeps and Monte Carlo simulations with component tolerances and process variations.
04Robust job management: Simulations run as cancellable jobs with timeouts and concurrency limits, and results report facts with simulator warnings for agent interpretation.
05Co-design workflow: Facilitates iterative design by allowing assistants and human users to collaboratively edit and verify circuits using standard LTspice and SPICE files.
