Connect Attlasian MCP from a custom web Application

[Priyadarshini R]

I am able to connect to Attlasian MCP from our internal web application through MCP-Remote. But we are unable to establish interactive oauth when we host it. Can you please share how to conenct Attlasian MCP with an Production level Web Application ?

You can add the domains you trust or block Atlassian-supported domains in the admin portal.

Hi Aaron, thanks for the reply. We are able to connect to the Atlassian MCP server successfully from our internal web app using "mcp remote".

However, the issue we are facing is not domain blocking.

It is with the interactive OAuth 2.1 flow when the app is hosted in production.

Locally, on localhost with "mcp remote", the browser based Atlassian login and consent flow works as expected.

• In production, on our hosted domain, the OAuth redirect flow fails. The consent screen does not complete or redirect back to our app correctly.
• Because of this, we cannot establish a valid MCP session token for production users.

We are trying to understand the following.

• Whether custom web applications are officially supported as MCP clients today beyond localhost and "mcp remote".
• If so, what the correct OAuth 2.1 configuration is for production:
  • Required redirect URI format
  • PKCE expectations
  • any allowlisting of client IDs or domains.
• Whether Atlassian currently restricts non approved MCP clients from completing OAuth in production environments.

Could you please clarify if production web apps are supported today, and if there is any additional setup required beyond OAuth 2.1 and MCP.

Hi, Yes, production web apps should work too and there is no additional setup needed from OAuth perspective.

May be adding the IP to the allowed-list will help, see this:

If it still doesn't work, pls file a support ticket and we will investigate further
