You deploy a DigiKey MCP Server to enable fast, programmable access to DigiKey’s Product Search API. Built with FastMCP, it exposes a set of search and product detail tools that you can query from MCP clients or programmatic FastMCP clients, making it easy to integrate DigiKey product data into your applications.

How to use

You interact with the DigiKey MCP Server through an MCP client or a FastMCP client. Use the provided search methods to find DigiKey products by keyword, with optional sorting and filtering, and combine those results with product details, pricing, and media requests as needed. You can also fetch complete category and manufacturer information, or discover substitute products when relevant.

How to install

Prerequisites you must have before running the server:

Python 3.10+
uv package manager
DigiKey API credentials (CLIENT_ID and CLIENT_SECRET)

Step 1 – Install dependencies and prepare the environment:

uv sync

Step 2 – Set up environment variables for DigiKey credentials and sandbox mode. Create a file named .env in your project root with the following contents:

CLIENT_ID=your_digikey_client_id
CLIENT_SECRET=your_digikey_client_secret
USE_SANDBOX=false

If you want to run against DigiKey’s sandbox environment, set USE_SANDBOX=true in the same file.

Step 3 – Run the server. Start the MCP server using the following command:

uv run python digikey_mcp_server.py

Additional sections

Configuration notes and operational details are kept within the server runtime. The server relies on environment variables for authentication and environment selection. Make sure your .env file is accessible to the runtime process and that the DigiKey credentials are valid for the selected environment.
