What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

PyPIPython’s uv installed (for the uvx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "electronic": {
      "command": "uvx",
      "args": [
        "electronics-mcp-servers"
      ]
    }
  }
}

Run this in your terminal

claude mcp add electronic -- uvx electronics-mcp-servers

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "electronic": {
      "command": "uvx",
      "args": [
        "electronics-mcp-servers"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "electronic": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "electronics-mcp-servers"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Electronics MCP Servers safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 10 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

Electronics MCP Servers

A comprehensive Model Context Protocol (MCP) server providing 14 electronics engineering tools across 3 domains.

Installation

pip install electronics-mcp-servers

Testing & Verification

After installation, verify the package is working:

Test with uvx (recommended for MCP clients)

# Alternative: Test individual servers

uvx --from electronics-mcp-servers resistor-decoder uvx --from electronics-mcp-servers capacitor-calc uvx --from electronics-mcp-servers gpio-reference

Test with pip install

# After pip install, test the CLI

electronics-mcp-servers --version

Or test individual tools

resistor-decoder --help capacitor-calc --help gpio-reference --help

Naming Clarification

This project uses different naming conventions in different contexts:

MCP Registry ID: io.github.wedsamuel1230/electronic-mcp-server (singular)
PyPI Package: electronics-mcp-servers (plural)
CLI Executables: electronics-mcp-servers, resistor-decoder, capacitor-calc, gpio-reference

When using uvx, always use the PyPI package name (electronics-mcp-servers).

Troubleshooting

Problem: uvx electronics-mcp-servers shows "executable not provided" error

Solution: The main electronics-mcp-servers executable was added in version 1.0.2. Make sure you have the latest version:

# Force uvx to fetch the latest version

uvx --refresh electronics-mcp-servers

Or specify the version explicitly

uvx --from electronics-mcp-servers==1.0.2 electronics-mcp-servers

Check installed version

pip index versions electronics-mcp-servers

If the error persists, PyPI may still be serving version 1.0.1. Wait a few minutes and try again.
