TechInterview.live — Official MCP Plugin (`techinterview-plugin`)

Connect OpenAI Codex, ChatGPT, Claude, Claude Code, and Gemini CLI to your techinterview.live account via OAuth 2.1 PKCE.

Designed for Engineering Managers, Hiring Managers, and Tech Leads to:

Grill the EM (grill-interview-architect Skill): Socratic 2–3 turn discovery that turns real production failure modes into calibrated Junior, Mid, or Senior coding and system design challenges—never generic LeetCode trivia.
Build Your Question & Challenge Library for Free (0 Credits): Create and edit collaborative coding questions (Monaco) and system design architecture diagrams (Mermaid → Excalidraw canvas) with private interviewer rubrics.
Assemble Multi-Question Challenges (0 Credits): Combine existing and newly created questions into ordered interview loops for personal or team workspaces.
Launch Live Interview Sessions (1 Credit): Start live candidate sessions (https://techinterview.live/r/<hash>) using your credits, or generate a hosted Stripe Checkout link on demand when topping up.
