Onlinecomponents MCP: component stock and specs in a chat

Need a part's stock level before you finalize a bill of materials? Onlinecomponents' MCP server searches real-time stock, pricing and specs for electronic components on OnlineComponents.com. ContextGate connects it to Claude, ChatGPT and Cursor with your Onlinecomponents sign-in, so the sourcing check happens in the chat and each part search can be traced later.
