Show HN: Open-source app store for Claude

Hey folks, we at June (YC W21) built an open-source app store for Claude which makes installing MCPs in Claude super easy. We've been using MCPs within Claude for a while and 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.

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. So we built a desktop app that handles the complexity of installing the right tools in the environment to make MCP installation super easy.

The app itself is open-source and it runs only on your machine. Your data only goes to Anthropic when you ask Claude to do something with it. You can find the GitHub repo here: https://github.com/fleuristes/fleur. 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 had errors and didn't work. We're also trying to figure out a way to make the Google OAuth flow very smooth before we add the Gmail and Calendar MCPs.

Let us know what you think!

One of the makers here - it was really fun to build this

While things seem to be still very early and each tool call needs to be manually approved in Claude, using these MCPs for some of our non developer friends was mind blowing

I think while it's still unclear what the winning way to build these integrations between apps and LLMs will be we need early experiments like this one for people to understand what's possible
