Purpose
This server provides AI agents with the ability to read and analyze electrical schematics from Cadence and Altium designs. It acts as a bridge, allowing AI tools to review electronic design files through natural language.

Security Assessment
Overall Risk: High. While no hardcoded secrets or dangerous permissions were requested, the tool exhibits potentially dangerous behaviors. It instructs users to install via remote script execution (`curl | bash` and PowerShell equivalents). Additionally, the codebase fails checks for containing `rm -rf` (recursive force deletion) commands in its `package.json` and build scripts. Because it requires reading proprietary `.dat` and `.SchDoc` files, it inherently accesses sensitive intellectual property and proprietary design data.

Quality Assessment
The project is actively maintained (last push was today) and properly licensed under Apache-2.0. However, it suffers from very low community visibility with only 9 GitHub stars, meaning the code has not been extensively peer-reviewed. Exercise caution regarding the maturity and reliability of a niche tool with minimal public scrutiny.

Verdict
Not recommended due to the combination of sensitive data access, unverified remote script installation, and destructive shell commands in the codebase.
SUMMARY

Give AI agents the power to read Cadence/Altium designs

README.md

Universal Netlist MCP Server

The Universal Netlist MCP Server gives AI agents the tools to understand and analyze your electrical schematics, for powerful and comprehensive design reviews through natural conversations.

It is compatible with Cadence and Altium, with plans to integrate more EDAs in the future. Note that you must already own a license of these EDAs to unleash the full capabilities of this MCP server.

Supported Formats

Format Input Files Description
Cadence (CIS / HDL) .dat netlist files Exported Allegro netlist files (pstxnet.dat, pstxprt.dat, pstchip.dat) from Cadence Capture CIS or HDL designs
Altium Designer .SchDoc Altium schematic documents (discovered via .PrjPcb project files)

Native Install (Recommended)

macOS / Linux:

curl -fsSL https://raw.githubusercontent.com/IntelligentElectron/universal-netlist/main/install.sh | bash

Windows (PowerShell):

irm https://raw.githubusercontent.com/IntelligentElectron/universal-netlist/main/install.ps1 | iex

Why use the native installer:

  • No dependencies — standalone binary, no Node.js required
  • Auto-updates — checks for updates on startup
  • Signed binaries — macOS binaries are notarized by Apple

The installer downloads two files:

  1. Binary - For CLI usage and manual MCP client configuration
  2. Claude Desktop extension (.mcpb) - For easy Claude Desktop integration
Platform Install Directory
macOS ~/Library/Application Support/universal-netlist/
Linux ~/.local/share/universal-netlist/
Windows %LOCALAPPDATA%\universal-netlist\

Update

The server checks for updates on startup. To update manually:

universal-netlist --update

Alternative: Install via npm

For developers who prefer npm:

npm install -g @intelligentelectron/universal-netlist

Or use with npx (no installation required):

npx @intelligentelectron/universal-netlist --help

Requires Node.js 20+.

To update:

npm update -g @intelligentelectron/universal-netlist

Connect the MCP with your favorite AI tool

After installing the MCP with one of the methods above, you can connect it to your AI agent of choice.

Claude Desktop

  1. Download the Claude Desktop app
  2. Open Claude Desktop and go to Settings (gear icon)
  3. Under Desktop app, click Extensions
  4. Click Advanced settings
  5. In the Extension Developer section, click Install Extension...
  6. Navigate to your install directory and select universal-netlist.mcpb:
    • macOS: ~/Library/Application Support/universal-netlist/universal-netlist.mcpb
    • Windows: %LOCALAPPDATA%\universal-netlist\universal-netlist.mcpb

The extension will be available immediately in your conversations.
