What It Provides
- MCP server:
https://aient.ai/mcp - Skill: skills/aient/SKILL.md
- Marketplace metadata and brand assets for the Codex plugin UI

Install From The Repo Marketplace
The Aient plugin is published through the repo marketplace at
.agents/plugins/marketplace.json.
codex plugin marketplace add https://github.com/hashgraph-online/awesome-codex-plugins.git --ref main --sparse .agents/plugins --sparse plugins/haf/aient-codex-plugin
codex plugin add aient
After installing or updating the plugin, start a new Codex thread so newly available skills and MCP tools are loaded.
The production MCP server uses OAuth-protected HTTP MCP. Codex should start the OAuth flow when the plugin connects and request the scopes required for Aient's read and write MCP tools.
Maintenance
Keep this public plugin bundle focused on customer-facing install metadata, skills, brand assets, and MCP configuration.
