How to Set Up and Use Altium

The Altium MCP Server is a native desktop extension (.dxt) that connects Claude Desktop directly to a running instance of Altium Designer, exposing PCB and schematic design capabilities through natural language. It covers component data retrieval, schematic symbol creation from datasheets, PCB net management, layer visibility control, footprint creation, running Output Jobs, and taking screenshots of design windows. Hardware engineers use it to automate repetitive Altium tasks — like bulk property updates or symbol generation — without writing custom Altium scripting API code.

Prerequisites

  • Altium Designer installed on Windows (the server auto-detects installations under C:\Program Files\Altium\AD*)
  • Python 3.10+ available in your Altium Designer Python scripting environment
  • Claude Desktop installed on the same Windows machine
  • No external API keys required — all operations are local
1

Download the extension package

Download the latest altium-mcp.dxt file from the GitHub releases page at https://github.com/coffeenmusic/altium-mcp/releases.

2

Install the extension in Claude Desktop

In Claude Desktop, open Settings → Extensions → Advanced, then click 'Install Extension...' and select the downloaded altium-mcp.dxt file. No restart is required.

3

Verify Altium Designer is running

Open Altium Designer with a project loaded before making MCP tool calls. The extension auto-locates the highest installed Altium version. If it cannot find it, a manual file picker will appear.

4

Allow the bootstrap virtual environment to install

On first launch, start_server.py creates a server/.venv/ directory and installs pinned dependencies (mcp==1.5.0, pillow, pywin32). This takes 20-30 seconds. Subsequent launches are instant.

5

Confirm the tool appears in Claude Desktop

After installation, look for the Altium tool icon in the toolbar near the search bar in Claude Desktop. Click it to see the list of available PCB and schematic tools.

Altium Examples

Client configuration

The Altium MCP server is installed as a .dxt extension in Claude Desktop and does not require a manual JSON config entry. For reference, the equivalent manual config would look like this.

{
  "mcpServers": {
    "altium": {
      "command": "python",
      "args": ["C:\\path\\to\\altium-mcp\\server\\start_server.py"],
      "env": {}
    }
  }
}

Prompts to try

Example prompts for controlling Altium Designer through Claude.

- "Run all output jobs in the current project"
- "Create a schematic symbol for the LM358 op-amp using the attached datasheet"
- "Find the LM358 symbol in my opamp library and open it for editing"
- "Get all components in the current design made by Molex with their designators and part numbers"
- "Take a screenshot of the current PCB layout window"

Troubleshooting Altium

Extension installs but no Altium tools appear in Claude Desktop

Ensure Altium Designer is running before opening Claude Desktop. The server needs an active Altium instance to connect to. Reopen Claude Desktop after launching Altium.

First launch takes a long time with no feedback

The bootstrap step creates a virtual environment and downloads dependencies (mcp, pillow, pywin32). This can take 20-30 seconds on the first run. Subsequent launches are fast. Check Task Manager for a Python process to confirm it is running.

Altium Designer is not detected automatically

The server searches C:\Program Files\Altium\AD* for the X2.EXE binary. If your Altium is installed elsewhere, a manual file picker will appear. Select the X2.EXE from your custom installation path.
