blender-mcp vs ltspice-mcp
blender-mcp: Blender MCP integrates Blender with Large Language Models, enabling prompt-assisted 3D modeling, scene creation, and manipulation. It provides a powerful bridge for AI-driven design workflows, allowing users to control Blender through natural language commands and generate assets.; 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.

TL;DR
blender-mcpAPI Integration · ★ 32.0k
When to choose:
- You work in Blender for 3D modeling, rendering, or level design and want to direct AI agents via natural language to build and modify meshes and shaders.
- You want to automate asset sourcing from Poly Haven, Sketchfab, and 3D generative APIs (Rodin, Hunyuan3D) directly onto your 3D viewport.
When to skip:
- Your workflow is inside game engines like Unity or Unreal Engine rather than DCC tools; use dedicated Unity-MCP or UE5-MCP instead.
- You are not familiar with Blender's pipeline and only want a simple web-based image-to-3D generator without local DCC software.

Features
blender-mcp01Two-way communication: Connect Claude AI to Blender through a socket-based server.
02Object manipulation & Material control: Create, modify, and delete 3D objects; apply and modify materials and colors.
03Scene inspection & Code execution: Get detailed information about the current Blender scene; run arbitrary Python code in Blender from Claude.
04Asset & model generation: Integrate Poly Haven, Sketchfab models, and AI-generated 3D models via Hyper3D Rodin and Hunyuan3D.
ltspice-mcp01Simulation 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.
