OpenAI App Submission – Tool scan failed: Internal service error
OpenAI Developer Community
March 20, 2026
No solution has been found, still causing a 500 error.
The error has been:
• Attempted by multiple users
• Attempted in fully verified org
• Attempted on multiple MCP servers
• Attempted in different orgs
All of the above trigger the 500 error when the MCP size is larger than an unclear limit. Extensive triage reports have been sent to support.
