One-Click MCP server installation for Claude Desktop

This feels like a pretty big step forward for MCP and Claude users, while also attempting to make it easier for MCP server developers to ship and app developers to integrate with MCP.

As someone who has already broken Claude Desktop by manually messing with config JSON file, I’m pumped for this new feature. It is so easy now to install the extensions and the servers because there is no more working with the Terminal and manually updating the config file. It’s all done in Claude Desktop in the new dedicated Extensions tab in Settings.

If you’re into this sort of stuff I’d highly recommend reading the launch article. But if you want just a quick summary, here’s what we got today: "

“We're open-sourcing: The complete DXT specification Packaging and validation tools Reference implementation code TypeScript types and schemas This means: For MCP server developers: Package once, run anywhere that supports DXT For app developers: Add extension support without building from scratch For users: Consistent experience across all MCP-enabled applications"
