tidy3d

tidy3d is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from flexcompute/plugin-marketplace. Its token cost is not measured, scanned A, original, no licence file.

A locally run MCP server for Tidy3D. Tidy3D is software for simulating how electromagnetic waves behave, and MCP connects such tools to an AI agent.

In plain words
What is it for?
Use it to connect an agent to the local Tidy3D package; the concrete supported jobs are not stated in the input.
Why use it?
It gives the agent a local connection to Tidy3D without describing the server’s individual operations. The input does not specify which simulations or actions are supported.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add mcp/flexcompute/plugin-marketplace/flex-rf-tidy3d
Clone the repo
git clone --depth 1 https://github.com/flexcompute/plugin-marketplace

Made for: Claude Code, Codex, Cursor, Gemini CLI, OpenCode.

Or install flex-rf, the plugin that ships this one along with the rest of its 1 skill, 1 MCP server.

Security

Grade A, and why

tidy3d scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tidy3d is an MCP server published in the GitHub repository flexcompute/plugin-marketplace (8 stars, last pushed yesterday), with no licence file. Its token cost is not measured: an MCP server costs its tool schemas, not its config file. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
