[BUG] Claude Desktop OAuth token missing scopes breaks Dispatch and Marketplace (user:inference only)

Bug Description

Claude Desktop v2.1.51 (macOS) generates OAuth tokens with only user:inference scope during authentication. This causes Dispatch (remote task management from mobile) and Marketplace (plugin marketplace) to be completely non-functional.

Impact

• Dispatch: Projects do not appear on mobile (claude.ai). Users cannot work remotely on their projects.
• Marketplace: Shows "Marketplace not found" error. Plugin marketplace is inaccessible.
• Paying subscribers (Max plan) are unable to use key advertised features.

Root Cause

Debug logs confirm the OAuth token is issued with insufficient scopes:

[claudeai-mcp] Missing user:mcp_servers scope (scopes=user:inference)
AxiosError: [url=https://api.anthropic.com/api/oauth/profile,status=403,body=OAuth token does not meet scope requirement any_of(user:profile, user:office)]
AxiosError: [url=https://api.anthropic.com/api/oauth/claude_cli/client_data,status=403,body=OAuth token does not meet scope requirement user:profile]

The token only includes user:inference but is missing:

• user:profile
• user:mcp_servers
• user:sessions:claude_code

Steps to Reproduce

1. Open Claude Desktop (v2.1.51 on macOS)
2. Use Code mode with a trusted project folder
3. Try to access the project via Dispatch on mobile → Project does not appear
4. Check for Marketplace → "Marketplace not found" notification

Attempted Fixes (none worked)

1. Sign out and sign back in → Same limited scopes
2. Clear OAuth token cache (oauth:tokenCache in config.json) and re-authenticate → Same limited scopes
3. Restart Claude Desktop completely → Same limited scopes

Environment

• Claude Desktop version: 2.1.51
• Claude Code (embedded): 2.1.51
• OS: macOS Darwin 25.3.0
• Entry point: claude-desktop (Agent SDK)
• coworkScheduledTasksEnabled: true in config
• Project folder is in localAgentModeTrustedFolders

• #34990 — Remote Control: OAuth token missing user:sessions:claude_code scope
• #35879 — Marketplace not found in configuration

Expected Behavior

OAuth token should include all necessary scopes (user:inference, user:profile, user:mcp_servers, user:sessions:claude_code) so that Dispatch and Marketplace work correctly for paying subscribers.
