What each surface is for
- Postsiva GPT is for guided user-facing workflows inside ChatGPT Apps.
- MCP is for tool access from clients like Cursor, Claude, or other agent-capable environments.
- Both should respect the same workspace boundaries and permission model as the web app.
Operational advice
- Start with low-risk drafts before attempting broader automation.
- Keep an eye on plan limits and key scopes when experimenting.
- Treat agent-connected publishing as part of the same review process you use in the app.
