Hi,
My Atlassian MCP connection to Claude broke 2 days ago after working for months.
I have since tried everything to re-establish the connection without luck.
Claude's attempts to fix it have been unsusucessful.
I'm not sure on this but I did find a good reference that should be helpful.
Check the answer on page: Atlassian MCP Integration with Claude Completely Stopped Working - Need Help!
Hope it helps!
Hi @Alexandra Klock ,
This is a common issue with Atlassian MCP + Claude integrations breaking. Here's the fix:
Most likely cause: Your OAuth token expired or was revoked.
Quick steps:
Revoke the old connection — Go to Atlassian API tokens and remove the old MCP token.
Re-authenticate — In Claude, remove the MCP server config, then re-add it fresh with a new OAuth flow.
Check scopes — Ensure the required scopes (read:confluence-content.all, read:jira-work, etc.) are granted during re-auth.
Verify the MCP server URL — Atlassian recently updated some endpoints; make sure you're using the latest config from the https://developer.atlassian.com/cloud/mcp/.
If it still fails: Clear Claude's MCP cache (delete ~/.claude/mcp.json or equivalent) and start the connection from scratch.
Just to confirm - you're using MCP integration and not the native Atlassian <> Claude connector?If we're talking about MCP, can you share how you've configured it? 👀
Note that in 3 days (30th June 2026), usage of <a href="https://mcp.atlassian.com/v1/sse" target="_blank" rel="nofollow noopener noreferrer">https://mcp.atlassian.com/v1/sse</a> as a server endpoint will no longer be supported.There's more info around that here: Setting up clients

Hi @Tomislav Tobijas
I had been using the Atlassian MCP connector through Claude Dektop (via the chat option) to manage and create confluence pages.
This is the current config:
{"mcpServers": {"atlassian": {"command": "npx","args": ["-y","mcp-remote","https://mcp.atlassian.com/v1/mcp/authv2"]}},
I've just tried using Atlassian <> Claude connector on desktop (Windows OS), and it all seems to be working fine 👀
Can you maybe try reinstalling the connector to see how it will behave?
