MMEHDI0606 MiniMax CLI — Agent Skill Guide
Use mmx to generate text, images, video, speech, music, and perform web search via the MiniMax AI platform.
Prerequisites
# Install
npm install -g mmx-cli
# Auth (OAuth persists to ~/.mmx/credentials.json, API key persists to ~/.mmx/config.json)
mmx auth login --api-key sk-xxxxx
# Verify active auth source
mmx auth status
# Or pass per-call
mmx text chat --api-key sk-xxxxx --message "Hello"
Region is auto-detected. Override with --region global or --region cn.
Agent Flags
Always use these flags in non-interactive (agent/CI) contexts:
| Flag | Purpose |
|---|---|
--non-interactive |
Fail fast on missing args instead of prompting |
--quiet |
Suppress spinners/progress; stdout is pure data |
--output json |
Machine-readable JSON output |
--async |
Return task ID immediately (video generation) |
--dry-run |
Preview the API request without executing |
--yes |
Skip confirmation prompts |
Commands
text chat
Chat completion. Default model: MiniMax-M2.7.
mmx text chat --message <text> [flags]
# Single message
mmx text chat --message "user:What is MiniMax?" --output json --quiet
# Multi-turn with system prompt
mmx text chat \
--system "You are a coding assistant." \
--message "user:Write fizzbuzz in Python" \
--output json
# From file
cat conversation.json | mmx text chat --messages-file - --output json
image generate
Generate images. Model: image-01.
mmx image generate --prompt <text> [flags]
mmx image generate --prompt "A cat in a spacesuit" --output json --quiet
mmx image generate --prompt "Logo" --n 3 --out-dir ./gen/ --quiet
video generate
Generate video. Default model: MiniMax-Hailuo-2.3. Async task — polls until completion by default.
mmx video generate --prompt <text> [flags]
# Non-blocking: get task ID
mmx video generate --prompt "A robot." --async --quiet
# Blocking: wait and save file
mmx video generate --prompt "Ocean waves." --download ocean.mp4 --quiet
speech synthesize
Text-to-speech. Default model: speech-2.8-hd. Max 10k chars.
mmx speech synthesize --text <text> [flags]
mmx speech synthesize --text "Hello world" --out hello.mp3 --quiet
echo "Breaking news." | mmx speech synthesize --text-file - --out news.mp3
music generate
Generate music. Model: music-2.6-free.
mmx music generate --prompt <text> [--lyrics <text>] [flags]
# Instrumental
mmx music generate --prompt "Cinematic orchestral, building tension" --instrumental --out bgm.mp3 --quiet
# With auto-generated lyrics
mmx music generate --prompt "Upbeat pop about summer" --lyrics-optimizer --out summer.mp3 --quiet
search query
Web search via MiniMax.
mmx search query --q "MiniMax AI" --output json --quiet
vision describe
Image understanding via VLM.
mmx vision describe --image photo.jpg --prompt "What breed?" --output json
Piping Patterns
# Chain: generate image → describe it
URL=$(mmx image generate --prompt "A sunset" --quiet)
mmx vision describe --image "$URL" --quiet
# Async video workflow
TASK=$(mmx video generate --prompt "A robot" --async --quiet | jq -r '.taskId')
mmx video task get --task-id "$TASK" --output json
mmx video download --task-id "$TASK" --out robot.mp4
Exit Codes
| Code | Meaning |
|---|---|
| 0 | Success |
| 1 | General error |
| 2 | Usage error |
| 3 | Authentication error |
| 4 | Quota exceeded |
| 5 | Timeout |
| 10 | Content filter triggered |
Limitations
- Requires a configured MiniMax account and valid authentication before any API-backed command will work.
- Media-generation tasks can be async, quota-limited, or region-constrained; agents should handle delayed completion and provider-side failures explicitly.
- This skill documents CLI usage only and does not replace provider policy review, content-safety checks, or downstream file validation.
