Claude Code TierFlow Setup

This guide shows how to connect Claude Code to TierFlow.

Basic information:

Item	Value
Base URL	http://47.99.200.103:8003/anthropic
Authentication	Bearer Token
Protocol	Anthropic API Compatible
Model	auto

1. Check That Claude Code Is Installed

Windows PowerShell:

claude --version

macOS / Linux terminal:

claude --version

If a version number is shown, Claude Code is installed. For example:

2.1.143 (Claude Code)

2. Config File Locations

Claude Code mainly uses two config files:

System	settings.json	.claude.json
Windows	C:\Users\YOUR_USERNAME\.claude\settings.json	C:\Users\YOUR_USERNAME\.claude.json
macOS	/Users/YOUR_USERNAME/.claude/settings.json	/Users/YOUR_USERNAME/.claude.json
Linux	/home/YOUR_USERNAME/.claude/settings.json	/home/YOUR_USERNAME/.claude.json

3. Create the .claude Folder

Windows

Open File Explorer and enter this in the address bar:

%USERPROFILE%

Create this folder under your user directory:

.claude

macOS

Open Terminal:

mkdir -p ~/.claude
open ~/.claude

You can also open Finder, press Command + Shift + G, and enter:

~/.claude

Linux

Open Terminal:

mkdir -p ~/.claude

If you use a file manager, open your home directory, show hidden files, then enter .claude.

4. Create settings.json

Create this file inside the .claude folder:

settings.json

Write:

{
  "env": {
    "ANTHROPIC_BASE_URL": "http://47.99.200.103:8003/anthropic",
    "ANTHROPIC_AUTH_TOKEN": "YOUR_API_KEY_HERE",
    "ANTHROPIC_MODEL": "auto",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "auto",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "auto",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "auto"
  }
}

Replace:

YOUR_API_KEY_HERE

with your real API key.

5. Create .claude.json

Create this file in your user directory:

.claude.json

Write:

{
  "hasCompletedOnboarding": true
}

File locations:

Windows:

C:\Users\YOUR_USERNAME\.claude.json

macOS:

/Users/YOUR_USERNAME/.claude.json

Linux:

/home/YOUR_USERNAME/.claude.json

6. Restart the Terminal

Close the current terminal and open it again.

Enter your project directory:

Windows PowerShell:

cd C:\path\to\your\project

macOS / Linux:

cd /path/to/your/project

Start Claude Code:

claude

When entering a project for the first time, select:

Trust This Folder

7. Verify the Setup

In Claude Code, type:

/status

Confirm the model is:

auto

Then test with:

Reply exactly OK.

If Claude Code returns a normal response, the setup is complete.

8. VS Code Extension Setup

If you use the Claude Code VS Code extension, configure VS Code settings.json like this:

{
  "claudeCode.preferredLocation": "panel",
  "claudeCode.selectedModel": "auto",
  "claudeCode.environmentVariables": [
    {
      "name": "ANTHROPIC_BASE_URL",
      "value": "http://47.99.200.103:8003/anthropic"
    },
    {
      "name": "ANTHROPIC_AUTH_TOKEN",
      "value": "YOUR_API_KEY_HERE"
    },
    {
      "name": "ANTHROPIC_MODEL",
      "value": "auto"
    },
    {
      "name": "ANTHROPIC_DEFAULT_SONNET_MODEL",
      "value": "auto"
    },
    {
      "name": "ANTHROPIC_DEFAULT_OPUS_MODEL",
      "value": "auto"
    },
    {
      "name": "ANTHROPIC_DEFAULT_HAIKU_MODEL",
      "value": "auto"
    }
  ]
}

9. Troubleshooting

Wrong File Name

Make sure the files are not named:

settings.json.txt
.claude.json.txt

On Windows, enable file extension display.

On macOS / Linux, you can check with:

ls -la ~/.claude ~/.claude.json

Claude Code Still Uses Official Claude

Check whether old global environment variables are set.

Windows PowerShell:

echo $env:ANTHROPIC_BASE_URL
echo $env:ANTHROPIC_AUTH_TOKEN

macOS / Linux:

echo "$ANTHROPIC_BASE_URL"
echo "$ANTHROPIC_AUTH_TOKEN"

If old values are shown, close and reopen the terminal. If these variables were written into a shell config file, remove the old config there.

Authentication Failed

Check this value in settings.json:

"ANTHROPIC_AUTH_TOKEN": "YOUR_API_KEY_HERE"

Make sure it has been replaced with your real API key.

Config Changed but Did Not Take Effect

Restart the terminal, VS Code, Cursor, Windows Terminal, or whichever program starts Claude Code.

10. Optional Command Write

Use this only if you have confirmed the paths and API key. Manual editing is safer for new users.

Windows PowerShell

Replace YOUR_API_KEY_HERE with your API key:

New-Item -ItemType Directory -Force "$env:USERPROFILE\.claude"

@'
{
  "env": {
    "ANTHROPIC_BASE_URL": "http://47.99.200.103:8003/anthropic",
    "ANTHROPIC_AUTH_TOKEN": "YOUR_API_KEY_HERE",
    "ANTHROPIC_MODEL": "auto",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "auto",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "auto",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "auto"
  }
}
'@ | Set-Content -Encoding UTF8 "$env:USERPROFILE\.claude\settings.json"

@'
{
  "hasCompletedOnboarding": true
}
'@ | Set-Content -Encoding UTF8 "$env:USERPROFILE\.claude.json"

macOS / Linux

Replace YOUR_API_KEY_HERE with your API key:

mkdir -p ~/.claude

cat > ~/.claude/settings.json <<'JSON'
{
  "env": {
    "ANTHROPIC_BASE_URL": "http://47.99.200.103:8003/anthropic",
    "ANTHROPIC_AUTH_TOKEN": "YOUR_API_KEY_HERE",
    "ANTHROPIC_MODEL": "auto",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "auto",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "auto",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "auto"
  }
}
JSON

cat > ~/.claude.json <<'JSON'
{
  "hasCompletedOnboarding": true
}
