IT Abyss in Claude, Claude Code and Codex

Take IT Abyss AI interviews and quizzes in your own chat — the results go to your progress.

Server URL

https://mcp.itabyss.pro/mcp

Without a subscription: 2 AI interviews, and quizzes from the same 10 sessions as on the website — a one-time allowance, not monthly. With one: no round limit.

Claude — web, desktop and mobile

Claude Free allows only one custom connector — if yours is taken, disconnect it first.

Press the button: claude.ai opens with the address filled in. Press Add.
Add to Claude
Press Connect, sign in to IT Abyss and allow access.
In a new chat, write: "Run a Go interview with me".

On Team and Enterprise the organization Owner adds it — send them this link.

Claude Code

With the plugin, questions and grades show as cards:

/plugin marketplace add Cybeaster/LLMSkills

/plugin install itabyss@claude-skills

Instead of the plugin, everything as text:

claude mcp add --transport http --scope user itabyss https://mcp.itabyss.pro/mcp

Then in Claude Code: /mcp → itabyss → Authenticate, sign in to IT Abyss and allow access.

Codex

codex mcp add itabyss --url https://mcp.itabyss.pro/mcp

A browser opens: sign in to IT Abyss and allow access. If it doesn't: codex mcp login itabyss.

ChatGPT — Business, Enterprise and Edu

For now this works only in ChatGPT Business, Enterprise and Edu: on personal plans ChatGPT does not let a third-party server save results.

Open chatgpt.com/plugins → + → Create custom MCP server.
Name it IT Abyss, paste this address into Server URL, set Authentication to OAuth.
https://mcp.itabyss.pro/mcp
Press I understand and want to continue → Create as a plugin, sign in to IT Abyss and allow access.
Install it from Plugins → Personal (the plugins you created yourself in the workspace), then type @IT Abyss in a chat and ask for an interview.

If something goes wrong

Wrong account connected, or want to revoke access? Account → "Connected apps" → "Disconnect".
