## Before you start

- You do not need programming knowledge to use this glossary.
- Keep the unfamiliar word or the guide you were reading in mind.

## 1. Start from your guide

Open Guide in Muse4AI. In supported articles, the first use of a glossary term links to its explanation.

## 2. Read the list below

The glossary list appears automatically below this article. Find the term and read its short explanation.

## 3. Return to the task

Return to your guide and continue the next step. For connection terms, start with [Connect your AI agent](https://muse4ai.lovable.app/docs/connect-overview).

- **AI agent** — An AI assistant that can use tools for you — for example Claude Code, Codex or Cursor. Muse4AI is one of those tools.
- **MCP** — Model Context Protocol: a common plug that lets an AI agent use outside tools. Muse4AI offers one at the address ending in /mcp.
- **API** — A way for programs to talk to each other. Muse4AI's API lets scripts and agents send jobs and fetch results.
- **API key** — A long password (it starts with msk_) that an agent sends with each request. You create, copy and delete keys in Settings › API & agent.
- **Tunnel** — A safe public web address that leads to Muse4AI on your PC, so cloud apps like Claude or Lovable can reach it. Your API key is still required.
- **Proxy** — A separate internet connection given to one Muse account so each account keeps its own connection. It is not a way around Muse's rules or limits.
- **Usage limit** — How much your Muse account can still create. It belongs to your Muse account; Muse4AI only reads and shows it.
- **Agent Skill** — A small folder of instructions (SKILL.md) that teaches an AI agent how to use a tool well.
- **Queue** — The list of every job — waiting, running, done or failed — with a picture and the prompt.

## If it doesn't work

### Do I need to memorize these terms?

No. Look them up when needed and follow the practical steps in the guide.

### What if a term is not listed?

Read the surrounding explanation in the relevant guide. For an agent-specific term, consult that agent’s documentation.
