You can run the DigiKey MCP Server to query the DigiKey Product Search API v4 through a reusable MCP gateway. Docker-based deployment simplifies lifecycle management, secret injection, and tool exposure to MCP clients like Claude Code or Claude Desktop.

How to use

Connect an MCP client to the server through the Docker MCP Toolkit. The gateway manages the container lifecycle, injects secrets as environment variables, and exposes a set of DigiKey tools for common product search workflows.

How to install

Prerequisites you need before installation:

DigiKey API credentials

Docker with MCP Toolkit support (included with Docker Desktop) is recommended.

Optional: Python 3.10+ if you prefer the standalone or pip-based setup.

Step-by-step: Docker MCP Toolkit workflow.

Step 1 — Build the Docker image

git clone https://github.com/simon-77/digikey-mcp.git
cd digikey-mcp
docker build -t digikey-mcp:latest .

Step 2 — Create a custom catalog

Create a catalog file at the following path so the gateway can discover your server.

version: 3
name: custom
displayName: Custom MCP Servers
registry:
  digikey:
    description: DigiKey component search, pricing, and datasheets via API
    title: DigiKey
    type: server
    image: digikey-mcp:latest
    secrets:
      - name: digikey.CLIENT_ID
        env: CLIENT_ID
      - name: digikey.CLIENT_SECRET
        env: CLIENT_SECRET
    env:
      - name: USE_SANDBOX
        value: "false"
      - name: DIGIKEY_LOCALE_SITE
        value: "US"
      - name: DIGIKEY_LOCALE_LANGUAGE
        value: "en"
      - name: DIGIKEY_LOCALE_CURRENCY
        value: "USD"
    tools:
      - name: keyword_search
      - name: product_details
      - name: search_manufacturers
      - name: search_categories
      - name: get_category_by_id
      - name: search_product_substitutions
      - name: get_product_media
      - name: get_product_pricing
      - name: get_digi_reel_pricing
    prompts: 0
    resources: {}

Change the env values to match your locale (e.g., AT/en/EUR for Austria).

## Step 3 — Register the catalog and enable the server

docker mcp catalog import ~/.docker/mcp/catalogs/custom.yaml docker mcp server enable digikey

## Step 4 — Set secrets

docker mcp secret set digikey.CLIENT_ID docker mcp secret set digikey.CLIENT_SECRET

## Step 5 — Connect an MCP client

docker mcp client connect claude-code
