tidy3d vs Multisim MCP
tidy3d is no longer listed on any marketplace we read: these are its last known data, as of 2026‑10‑24.
tidy3d is a plugin bundle for AI coding tools published by Flexcompute. No marketplace we read lists it any more. Multisim MCP is an MCP server published by yxy050208. Marketplaces we read that list it: 2 (Official MCP Registry, PyPI (MCP servers)). As of our marketplace pass on 2026-10-25. A plugin in this pair is no longer listed on any marketplace we read, so search engines are asked not to index the page.

Each figure is the marketplace's own and is never added up across marketplaces. A marketplace that publishes no figure shows none: no number is not zero.

What each says it does
tidy3d
Tidy3D simulation, API, and documentation guidance for AI coding agents.
Multisim MCP
Generate Multisim circuits, run simulations, export data, and create experiment reports.
How to run each
tidy3d
No data for an automatic command: what its marketplaces declare does not say unambiguously how to connect it.
Multisim MCP As a local MCP server: PyPI package
claude mcp add --transport stdio multisim-mcp -- uvx multisim-mcpCommands built only from what the marketplaces declare; the full set for every client is on each card.
Tools each declares
Neither one's marketplaces publish a list of tools, so there is nothing to compare.
Settings each asks for
The marketplaces of tidy3d publish no settings it asks for, so we do not compare settings.
