Atlassian Rovo MCP Server: Migrating from SSE to Streamable HTTP Before June 30

Atlassian deprecated the SSE endpoint for their Rovo MCP Server in early March 2026, and the hard shutdown is June 30, 2026. If your claude_desktop_config.json, .mcp.json, or VS Code settings currently include mcp.atlassian.com/v1/sse, your Jira and Confluence access via MCP stops working in thirteen days.

The fix is almost trivial: one URL change. But it matters that you do it before the deadline.

What Is Changing

The Atlassian Rovo MCP Server was originally accessible via two transport protocols:

	Old	New
Endpoint	`https://mcp.atlassian.com/v1/sse`	`https://mcp.atlassian.com/v1/mcp`
Transport	SSE (Server-Sent Events)	Streamable HTTP
Status	Deprecated — sunset June 30, 2026	Current — supported

The v1/sse endpoint is being removed, not just discouraged. After June 30, calls to it will fail.

SSE vs. Streamable HTTP — What Changed Architecturally

The old SSE transport used two separate connections: a GET endpoint that held open a long-lived Server-Sent Events stream for server-to-client messages, and a separate POST endpoint for client-to-server messages. This worked but created operational complexity — clients had to manage two connections and deal with reconnection logic across both.

Streamable HTTP (defined in the MCP spec as the current recommended transport) collapses this into a single endpoint. The client POSTs to /v1/mcp; the server responds either as a standard HTTP response or as a streamed response within that same connection. Simpler connection management, better compatibility with proxies and firewalls, and cleaner client implementation.

The practical result: your config gets shorter (one URL instead of potentially two), and the transport is more reliable over standard corporate network infrastructure.

Who Is Affected

You are affected if any of these describe your setup:

Your MCP config has mcp.atlassian.com/v1/sse anywhere in it
You set up the Atlassian MCP connection before March 2026 (when the new endpoint was introduced alongside the deprecation announcement)
You’re using an older tutorial or documentation that references the SSE endpoint

You are not affected if:

You’re using sooperset/mcp-atlassian — the community server. That’s self-hosted and uses its own transport; it has nothing to do with mcp.atlassian.com
You already set up the connection using the current /v1/mcp endpoint
You connect through Atlassian’s first-party integrations (the official Claude, ChatGPT, GitHub Copilot CLI, or VS Code Copilot Chat connectors), where Atlassian manages the transport internally

How to Migrate

Step 1: Find Your Config

Search for mcp.atlassian.com in your MCP configuration files. Common locations:

Client	Config file
Claude Desktop (Mac)	`~/Library/Application Support/Claude/claude_desktop_config.json`
Claude Desktop (Windows)	`%APPDATA%\Claude\claude_desktop_config.json`
Claude Code (project)	`.mcp.json` in your project root
Claude Code (user)	`~/.claude.json`
VS Code (MCP extension)	`.vscode/mcp.json` or VS Code settings
Cursor	`~/.cursor/mcp.json`
Gemini CLI	`~/.gemini/settings.json`

Step 2: Update the URL

Change every occurrence of /v1/sse to /v1/mcp:

Before:

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

After:

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

That’s the entire migration for most setups.

Client-Specific Configurations

Claude Desktop

Before (old SSE config):

{
  "mcpServers": {
    "atlassian": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://mcp.atlassian.com/v1/sse"
      ]
    }
  }
}

After (Streamable HTTP):

{
  "mcpServers": {
    "atlassian": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://mcp.atlassian.com/v1/mcp"
      ]
    }
  }
}

Claude Desktop uses stdio transport internally. The mcp-remote bridge is what converts stdio ↔ remote HTTP. You still need mcp-remote; you’re just pointing it at the new endpoint. Requires Node.js v18+.

Claude Code

In your .mcp.json:

{
  "mcpServers": {
    "atlassian": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://mcp.atlassian.com/v1/mcp"
      ]
    }
  }
}

Or, if your Claude Code client natively supports Streamable HTTP (Claude Code versions supporting direct HTTP transport):

{
  "mcpServers": {
    "atlassian": {
      "type": "http",
      "url": "https://mcp.atlassian.com/v1/mcp"
    }
  }
}

The type: "http" form skips mcp-remote entirely. Use whichever form your Claude Code version supports; both point at the same endpoint.

VS Code (MCP Extension)

In .vscode/mcp.json:

{
  "servers": {
    "atlassian": {
      "type": "http",
      "url": "https://mcp.atlassian.com/v1/mcp"
    }
  }
}

VS Code’s MCP extension supports Streamable HTTP natively (no mcp-remote needed). If you were using the proxy before, you can remove it.

Cursor

In ~/.cursor/mcp.json:

{
  "mcpServers": {
    "atlassian": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://mcp.atlassian.com/v1/mcp"
      ]
    }
  }
}

Cursor authentication issues with the Atlassian MCP server are tracked in issue #137. If you experience auth errors after migration, this is a known Cursor-specific problem unrelated to the transport change.

Gemini CLI

In ~/.gemini/settings.json:

{
  "mcpServers": {
    "atlassian": {
      "httpUrl": "https://mcp.atlassian.com/v1/mcp",
      "timeout": 30000
    }
  }
}

Gemini CLI natively supports Streamable HTTP via the httpUrl key.

Authentication After Migration

The transport change does not affect authentication. Your existing OAuth 2.1 credentials remain valid. You should not be prompted to re-authorize unless your token has expired or you clear stored credentials.

If you’re using API token authentication (headless or long-running setups): same behavior — token stays valid, just update the endpoint URL.

If the first connection after migration prompts for OAuth: complete the flow in your browser as usual. This is normal token refresh behavior, not a migration artifact.

What Breaks If You Don’t Migrate

After June 30:

All tool calls to the Atlassian MCP server will return connection errors
Your agent will have no access to Jira, Confluence, Compass, Jira Service Management, or Bitbucket Cloud through MCP
The authentication token stored by mcp-remote may still be valid, but the endpoint it points to will no longer respond

There is no graceful degradation — the endpoint stops responding.

Verifying the Migration

After updating your config:

Restart your MCP client (Claude Desktop, VS Code, etc.)
If using mcp-remote for the first time with the new endpoint, you’ll see a fresh OAuth flow — complete it
Test a simple read operation: “List my recent Jira issues” or “Search Confluence for [topic]”
If the tool call succeeds and returns data, the migration is complete

If you get a 401: Your OAuth token may have been associated with the old endpoint session. Clear mcp-remote's stored credentials (usually in ~/.mcp-remote/ or equivalent) and re-authorize.

If you get a connection refused or 404: Double-check the URL — verify it reads /v1/mcp, not /v1/sse or /v1/msp (a typo).

Migration Checklist

Search all MCP config files for mcp.atlassian.com
Replace every /v1/sse with /v1/mcp
Restart your MCP client
Re-authorize if prompted (OAuth refresh)
Confirm tool calls work: run a Jira or Confluence query
Update any team-shared configs (.mcp.json committed to repos, shared Cursor configs)
Update any documentation or runbooks that reference the old SSE endpoint

The Broader Context

The Atlassian Rovo MCP Server reached GA in February 2026 and covers six product areas: Jira, Confluence, Compass, Jira Service Management, Bitbucket Cloud, and cross-product Rovo Search. The SSE sunset is part of the MCP ecosystem-wide shift toward Streamable HTTP as the standard remote transport — the MCP specification itself moved in this direction, and most major MCP servers have followed.

For the community server (sooperset/mcp-atlassian, 5,000 stars), none of this applies — it’s self-hosted and uses its own transport layer. If you’re evaluating whether to stay on the official server or switch, our Atlassian MCP Server review covers both in depth, including the reliability issues still open on the official server (52 open issues as of May 2026, including the duplicate-creation bug in createJiraIssue).

This migration is the easy part. Two minutes. Do it before June 30.
