Unexpected status: needs_auth when trying to authenticate MCP after changing account (already authenticated)

[leobrqz]

Description

Context:
A couple people share the same computer, each use their own opencode account. Today, i changed the GO(zen) token to my account, and suddendly the MCP asked for authentication. I did the usual flow opencode mcp auth xxx, it opened the browser, i accepted, but it returned Unexpected status: needs_auth - when i do the same auth command again, it says valid credentials were found and asks if i want to reuse them, saying yes doesn't authenticate, opening opencode just shows the mcp needs auth and it's disabled.

I've tried clearing .config/opencode + .cache/opencode and .share/opencode

I've also removed the bearer token from opencode.json inside the project repo, and tried the key oauth and enabled, neither worked.

And i completely removed opencode.json and tried making it again, no luck.

This is the first time this happens.

This issue might be a duplicate of existing issues. Please check:

• MCP OAuth: opencode mcp auth doesn't refresh token in active sessions #21702: MCP OAuth auth completes successfully but the active connection still uses stale credentials — MCP continues to show as needing auth until opencode is restarted
• MCP OAuth flow fails before opening the browser #28741: MCP OAuth flow fails (browser never opens / auth returns unexpected status) in a similar re-authentication scenario

If your issue is distinct from these, please add a note clarifying how it differs.

Not quite duplicate, similar, but not exactly duplicate, similar to #21702

It's the supabase MCP.
