Using Atlassian MCP in n8n Cloud

Questions

Describe the problem/error/question

I want to connect the Atlassian MCP server to an agent to access our Confluence and Jira resources. I use https://mcp.atlassian.com/v1/sse as SSE and authenticate with Bearer Auth using an API token I created in my Atlassian profile.

What is the error message (if any)?

Error in sub node “MCP client” could not connect to your MCP server

Have you tried testing with api first to see that there’s no problem with your api token etc?

Hey there, yes, I’ve tested the token. I used the HTTP node with Bearer and Header Auth and it worked. But with the MCP node I doesn’t. Not sure if it’s a “me” problem or if it’s a general issue.

Could you please share me how did you use the SSE integration? I am trying to use the same. I was able to successfully integrate with mcp-atlassian using STDIO but this one with SSE fails. I am also facing the same challenge.

Not exactly sure what you mean. I use the MCP tool. Anyway, from what I’ve read in other posts, the Atlassian MCP server only supports O Auth atm. So if I get it right, the only hope is that n8n adds O Auth as an authentication method to the tool.

ok thanks, let me try it out.

It would be great to support OAuth as that seems to be the standard moving forward for remote MCPs. It would also be nice if the Atlassian supported a PAT - for the sake of non-human-in-the-loop workflows.
