This issue doesn't fully meet our contributing guidelines.

What needs to be fixed:

  • OpenCode version is required but missing
  • Operating System information is required but missing
  • Terminal information is required but missing
  • Steps to reproduce are required but missing (even if just "I ran opencode and used MCP")

The screenshot is helpful, but without version and system information, it's difficult to reproduce the issue. Please provide these details so we can help you better.


Additionally, this issue appears to be a duplicate:

This exact error has already been reported in #13042 ("MCP tools crash: TypeError on value.output.output in processor.ts"), which was filed just moments earlier and already includes:

  • Root cause analysis (AI SDK v6.0.74 breaking change)
  • Technical explanation and potential solutions
  • Affected components

Please check #13042 for more details and discussion. You can add your specific context there if needed.


Please edit this issue to address the missing fields within 2 hours, or it will be automatically closed. If you believe this was flagged incorrectly, please let a maintainer know.
