I don't get excited about the directories listing all the MCPs that do all these random things. However, I used claude to create an MCP that is a gateway to our system and it's enabled some pretty helpful functionality for us. I use claude cowork to create email designs using data and content from our CMS, it can push accepted work straight into our system, evaluate content, and analyze results. All of that used to be a manual tiring process. This removed a lot of drudgery and improved the quality as well.

When I first looked at MCP protocol, I did not like it. Then I realized, I don't have to care about the protocol. Claude can implement that for me and it did.
