Who it is for
Teams that want consistent AI instructions across roles rather than prompts kept in individual notes.
Browse and launch reusable AI agent contexts
Overview
Oi is a library of agent contexts, meaning packaged instructions and setup for a particular kind of work. The connector allows browsing public contexts as well as private ones held on the account, picking whichever matches the task, and starting it in ChatGPT or in Codex.
The aim is repeatability across a team. Instead of each person writing a prompt from scratch for design, engineering, research, or support work, one context is shared and reused. Contexts are called by name in the conversation, and the account holder can also list what is available before choosing.
Teams that want consistent AI instructions across roles rather than prompts kept in individual notes.
It treats agent instructions as a shared library that can be launched into either ChatGPT or Codex.
Availability
Oi is listed in the ChatGPT apps directory only. Carhaix Au Pty Ltd has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from Oi's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Carhaix Au Pty Ltd, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
