Use MiniMax in Claude Code

Steps

1. 1
   Step 1.

   Clear these environment variables first. MiniMax notes they take priority over the settings file and override the MiniMax configuration (also remove any exports of them from ~/.bashrc or ~/.zshrc).

   Terminal

   Copy

   unset ANTHROPIC_AUTH_TOKEN
   unset ANTHROPIC_BASE_URL

2. 2
   Step 2.

   Option 1 (one-click setup wizard): run the wizard and select Claude Code. It runs the official installer if needed, checks claude --version, updates ~/.claude/settings.json, and adds the MiniMax model list.

   Terminal

   Copy

   npx -y mmx-cli@latest agent setup

3. 3
   Step 3.

   Option 2 (edit the settings file): edit or create ~/.claude/settings.json and replace <MINIMAX_API_KEY> with your Subscription Key.

   JSON

   Copy

   {
     "env": {
       "ANTHROPIC_BASE_URL": "https://api.minimax.io/anthropic",
       "ANTHROPIC_AUTH_TOKEN": "<MINIMAX_API_KEY>",
       "CLAUDE_CODE_AUTO_COMPACT_WINDOW": "524288",
       "ANTHROPIC_MODEL": "MiniMax-M3.1-Flash-Preview[1m]",
       "ANTHROPIC_DEFAULT_SONNET_MODEL": "MiniMax-M3.1-Flash-Preview[1m]",
       "ANTHROPIC_DEFAULT_OPUS_MODEL": "MiniMax-M3.1-Flash-Preview[1m]",
       "ANTHROPIC_DEFAULT_HAIKU_MODEL": "MiniMax-M3.1-Flash-Preview[1m]"
     }
   }

4. 4
   Step 4.

   Go to your working directory, run claude, and select Trust This Folder to start.

   Terminal

   Copy

   claude

5. 5
   Step 5.

   Verify inside the TUI: /status should show ANTHROPIC_BASE_URL pointing to api.minimax.io/anthropic, and /model should show the active model as MiniMax-M3.1-Flash-Preview.
