MCPs (based on the Model Context Protocol by Anthropic) enable Claude to use tools that can do a variety of functions like searching the web, executing code, manipulating files, accessing APIs; basically interacting with things outside the conversation context.

We've been using MCPs within Claude for a while and have found them super useful. For example, with the Slack and Linear MCPs, we can ask Claude to find the last bug a customer reported in a shared slack channel, and open an issue on Linear with all the details.

While playing around with MCPs, we found that installing MCPs was not the most straightforward experience, especially for someone who doesn't have Python and Node set up on their computer. That was the motivation behind building Fleur as a desktop app to handle the complexity of installing all the right tools in the environment that the MCPs depend on.

The app itself is open-source and it runs just on your machine. Your data only goes to Anthropic when you ask Claude to do something with it.

We also have an app registry where you can submit more MCPs: https://github.com/fleuristes/app-registry. We're making sure that every MCP we add works really well because we found a ton of them which have errors and don't work out of the box.

Would love to know what you think!
