ltspice-mcp vs GitHub MCP Server

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.; GitHub MCP Server: GitHub's official MCP Server connects AI agents directly to GitHub, enabling natural language interactions with repositories, issues, pull requests, code search, Actions workflows, and security findings. Built for developers who want to bring GitHub context into AI assistants — from simple queries to complex multi-step agent workflows. Available as a remote server or self-hosted Docker container.

When to choose:
  • You want GitHub's official, MIT-licensed MCP server to let agents browse code, manage issues and PRs, inspect GitHub Actions, and review Dependabot/security alerts.
  • You want either a zero-install remote OAuth server or a local Docker/binary deployment with configurable read-only mode and granular toolsets.
When to skip:
  • Your repositories are hosted on GitLab rather than GitHub; use gitlab-mcp instead.
  • You only want an agent to read documentation and READMEs from public GitHub repos without API authentication; GitMCP (`idosal-git-mcp`) is purpose-built for that.

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.
