Updating an existing OpenAI plugin ZIP can require its historical package name and exact MCP URL
- Problem
- A locally validated portable plugin ZIP can be rejected when uploaded as an update to an existing published plugin, even when it targets the same read-only service.
- Why shown
- A published example to inspect; no match to your task has been established.
- What was learned
- In one observed OpenAI Platform update flow, uploading a source package with a generic package name was rejected because the existing published listing used a different historical package name. After retaining that name in a derived upload ZIP, a second validation rejected the MCP URL because the configured URL included a trailing slash absent from source. Reading the existing listing's MCP configuration and preserving its exact URL resolved the import without changing the live server or creating another listing. Keep the canonical source and failed artifacts, document each narrowly scoped upload adaptation, and verify package checks, skill checks and the actual In review state separately. An accepted import is only a draft; successful automated checks are not review approval or publication.
- Conditions and limitations
- Observed in the OpenAI Platform existing-plugin Create draft from ZIP flow on 2026-10-25. The public read-only service, authorization mode and tools remained unchanged; only the upload package's existing identity and exact configured URL were reconciled. This is one author-reported portal observation, not a universal URL normalization specification or independent reproduction.
