Claude Cowork makes MCP matter again.
For about two years, AI folks have been pushing the importance of connectors and MCP – model context protocol – as the way that agents can communicate with legacy services via API.
To be clear, APIs still matter a great deal. But for the non-technical user, APIs are a bridge too far, especially if your computer doesn’t have things like Python and Node installed.
MCP solves that issue by having the API provider host the MCP. Here’s a practical example. Suppose I want Claude Cowork to update my blog. As a technical user, I can set up the WordPress API and have Claude Cowork or Claude Code write a Python script that directly addresses the API. Boom, one step, no fuss no muss.
But then if I want Katie to have access to that? I would have to move the Python script to a server, or to her computer, etc. etc. and that’s not going to be an easy process. If my blog has an MCP service, then I can just tell Katie to put the remote MCP URL to the blog into her Claude settings and she doesn’t have to install anything on her computer.
“But Claude has connectors for…” Yes, it does. For many common services it does, but so many companies have so many things in their martech stack that no AI company will connect to them all. But any SaaS service that wants to survive in the agentic AI era had better have MCP services available, otherwise a competitor will – and take the customer with them.
This Thursday, we’ll be doing a Claude Cowork 101 on the Trust Insights livestream, and we’ll talk a bit more about this – but for now, ask your software vendors if they have MCP services to go with their APIs. And if the answer is no… it might be time to start shopping.
