Connect Lovable ​

Add Ybug to Lovable as a custom MCP server. Lovable's agent can then read the feedback your clients and testers leave on your app and fix it in the project, in the same chat.

Before you start

To collect feedback on your Lovable app, the Ybug widget needs to be on it. Install it first if you haven't yet. The MCP server needs a Ybug account on the BASIC plan or higher.

Add the server ​

  1. In Lovable, open Connectors, click Add custom and choose MCP server.
  2. Name it Ybug and paste https://mcp.ybug.io/mcp as the Server URL.
  3. If Lovable shows a Connection option, keep Direct connection. Keep OAuth as the authentication method.
  4. Click Add & authorize, then sign in to Ybug and approve access in the browser window.

If MCP server is grayed out, a workspace admin has turned off custom MCP servers. They can turn it back on in the Custom MCP row under Connectors → Admin settings → Chat connectors.

The connection is personal. Each teammate adds Ybug with their own Ybug account, so Lovable sees only what that person can see in Ybug. It shows up as Lovable under Connected apps, where you can disconnect it.

Fix feedback in your project ​

Open the Lovable project the feedback is about and ask in the chat. Name the Ybug project so the agent knows where to look:

List the open Ybug feedback on the Acme project from this week.

Read the Ybug report about the signup button on Acme and fix it in this project.

Go through the open high-priority bugs on Acme one by one. For each, tell me what you'd change before you change it.

Lovable reads the report from Ybug: the description, page URL, browser, device, console errors and failed requests. Then it changes the project with its own tools, and you check the result in the preview as with any other change. Ybug never changes your project.

Close the loop in Ybug STARTUP ​

Once the fix is in, Lovable can update the report too:

Add an internal note to the signup button report on Acme saying it's fixed in the latest version, and set it to Resolved.

Before a tool that changes something in Ybug runs, Lovable asks you to approve it. Allow once approves this one call, Always allow stops asking for that tool, and Skip cancels it. Tools that only read run without asking.

More ideas: Example prompts and workflows.

Good to know ​

  • Ybug is available in Lovable's chat only. It isn't part of your published app, and your app's visitors can't reach your feedback through it.
  • Lovable's own guide: Custom MCP servers.

Then check that it works.
