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, Altium, and KiCad, with plans to integrate more EDAs in the future. Note that the commercial EDAs (Cadence and Altium) require your own license to unleash the full capabilities of this MCP server; KiCad is free and open-source.

Supported Formats

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

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

Install OpenAI Codex, then run:

codex mcp add universal-netlist -- universal-netlist

Supported Platforms

Observability (OpenTelemetry)

The server can emit OpenTelemetry traces, metrics, and logs for every tool call, so you can integrate your own OTel service and see which tools are used, how long they take, and what fails. It is vendor-neutral and works with any OTLP-compatible backend (an OpenTelemetry Collector, Jaeger, Tempo, Prometheus, Honeycomb, Datadog, a managed cloud tracing service, etc.).

Telemetry is disabled by default with zero overhead, and is enabled and configured entirely through the standard OTEL_* environment variables — no code changes.

See Observability (OpenTelemetry) for setup, configuration, and the full list of emitted spans, metrics, and logs.

Documentation

See docs/ for API documentation and response schemas.

See CONTRIBUTING.md for development guidelines.
