Deadline: June 30, 2026. After that date, HTTP+SSE connections to Atlassian’s Rovo MCP Server stop working entirely.

If you’ve connected Jira, Confluence, or other Atlassian products to Claude Code, an AI agent, or any MCP client, you’re almost certainly using the HTTP+SSE transport at https://mcp.atlassian.com/v1/sse. That endpoint goes dark in 18 days.

The good news: migration is simple. You’re changing one URL. All your permissions, OAuth settings, and access controls carry over automatically.

What’s Being Deprecated and Why

Atlassian’s Rovo MCP Server has been supporting two transport types:

  • HTTP+SSE (/v1/sse) — the older transport, now deprecated
  • Streamable HTTP (/v1/mcp) — the newer, preferred transport, now mandatory

The MCP specification has evolved to prioritize Streamable HTTP over HTTP+SSE for reasons of reliability, security, session management, and compatibility with modern infrastructure like load balancers. HTTP+SSE was kept for backward compatibility but won’t receive further improvements and will be removed entirely after June 30, 2026.

This affects all uses of the Atlassian Rovo MCP Server — Claude Code integrations, custom AI agents, Copilot Studio connections, and any MCP client that uses the SSE endpoint.

The Migration: Update Your Endpoint URL

The migration is a single URL change in your MCP client configuration.

Change from:

https://mcp.atlassian.com/v1/sse

Change to:

https://mcp.atlassian.com/v1/mcp

That’s it. Permissions carry over. OAuth flows carry over. No re-authorization required.

How to Update Your Configuration

The exact steps depend on your MCP client. Here are the most common scenarios:

Claude Code (~/.claude/settings.json or equivalent)

In your MCP server configuration file, update the URL field for your Atlassian server entry. Look for a block referencing mcp.atlassian.com/v1/sse and update it to /v1/mcp.

The transport type should be set to streamable-http (some clients call this streamable-http or just http with the new endpoint).

Example configuration structure (adapt to your client’s exact format):

{
  "mcpServers": {
    "atlassian-rovo": {
      "url": "https://mcp.atlassian.com/v1/mcp",
      "transport": "streamable-http"
    }
  }
}

Note: The exact JSON structure varies by MCP client. Refer to your specific client’s documentation for the correct format. The key change is the URL — from /v1/sse to /v1/mcp.

OpenClaw Agent

If you’ve configured Atlassian MCP as a tool server in OpenClaw, locate your MCP server config (typically in your workspace config or skill configuration) and update the URL from /v1/sse to /v1/mcp. The transport type should be streamable-http or equivalent for your OpenClaw version.

Other MCP Clients

For any MCP-compatible client, search your configuration files for mcp.atlassian.com/v1/sse and replace it with mcp.atlassian.com/v1/mcp. Update the transport type to Streamable HTTP if your client requires explicit transport specification.

About the /v1/mcp/authv2 Variant

Some Atlassian documentation references a variant endpoint: https://mcp.atlassian.com/v1/mcp/authv2. This is used by certain clients that require OAuth 2.1 flows with resource indicators. If your client’s documentation or Atlassian’s setup guide for your specific tool specifies /v1/mcp/authv2, use that. For most standard MCP client setups, /v1/mcp is the correct endpoint.

Test Your Connection After Updating

After updating your configuration:

  1. Restart your MCP client or reload the server connection
  2. Test a simple Jira or Confluence query to verify connectivity
  3. Confirm permissions are intact (list a project, fetch a page, etc.)

If you encounter authentication errors after the update, check that your OAuth token or credentials haven’t expired — the migration itself doesn’t invalidate credentials, but it’s a good opportunity to verify your auth state is fresh.

What Happens If You Don’t Migrate

After June 30, 2026, connections to https://mcp.atlassian.com/v1/sse will fail. Your AI agent will lose access to Jira and Confluence entirely until you update the endpoint. Given how many workflows depend on Atlassian data, this is a disruption worth preventing now rather than debugging during an incident.

Why This Matters for Agent Builders

The shift from HTTP+SSE to Streamable HTTP is part of a broader pattern in the MCP ecosystem. Streamable HTTP is more robust for agentic workloads — better session management, better behavior behind proxies and load balancers, and cleaner error handling. If you’re building agents that depend on Atlassian data, this migration also brings reliability improvements beyond just avoiding the cutoff.

Atlassian is one of the most widely integrated platforms in enterprise AI agent setups. Jira for task tracking, Confluence for knowledge retrieval — both are common tool-call targets in production agentic workflows. Getting this migration done cleanly means no interruption to those workflows when the deadline hits.

Summary: What to Do Right Now

  1. Find any MCP configuration referencing https://mcp.atlassian.com/v1/sse
  2. Replace with https://mcp.atlassian.com/v1/mcp
  3. Update transport type to streamable-http if required by your client
  4. Test the connection
  5. Done

18 days until the cutoff. This is a 5-minute fix.
