Claude Code Integration

Claude Code is Anthropic’s official terminal-based coding agent. It understands your entire codebase and helps you code faster through natural language commands. This guide shows you how to connect Claude Code to LLMCloud.

Prerequisites

• macOS, Linux, or Windows (with WSL)
• Node.js 18+
• Claude Code installed (Installation guide)
• LLMCloud API key (Get one here)

Bypass Onboarding Screen

On first use, Claude Code normally shows an onboarding screen that attempts to authenticate with Anthropic directly. To skip this and use LLMCloud instead, choose one of the following methods:

claude.json (Recommended)

Create or edit ~/.claude.json:

{
  "hasCompletedOnboarding": true,
  "hasTrustDialogAccepted": true
}

CLI Flag

Run Claude Code with the skip permissions flag:

claude --dangerously-skip-permissions

Note: This flag must be used each time you start Claude Code.

Configuration

settings.json (Recommended)

Edit ~/.claude/settings.json:

{
  "env": {
    "ANTHROPIC_AUTH_TOKEN": "your_llmcloud_api_key",
    "ANTHROPIC_BASE_URL": "https://llmcloud.studio",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "anthropic/claude-opus-4.5-thinking",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "anthropic/claude-sonnet-4.5-thinking",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "anthropic/claude-haiku-4.5",
    "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": "1",
    "API_TIMEOUT_MS": "600000",
    "BASH_DEFAULT_TIMEOUT_MS": "600000",
    "BASH_MAX_TIMEOUT_MS": "600000",
    "MCP_TIMEOUT": "30000",
    "MCP_TOOL_TIMEOUT": "600000",
    "CLAUDE_API_TIMEOUT": "600000"
  }
}

Shell Profile

Add to ~/.zshrc or ~/.bashrc:

export ANTHROPIC_BASE_URL=https://llmcloud.studio
export ANTHROPIC_AUTH_TOKEN=your_llmcloud_api_key
export ANTHROPIC_DEFAULT_OPUS_MODEL=anthropic/claude-opus-4.5-thinking
export ANTHROPIC_DEFAULT_SONNET_MODEL=anthropic/claude-sonnet-4.5-thinking
export ANTHROPIC_DEFAULT_HAIKU_MODEL=anthropic/claude-haiku-4.5
export CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1
export API_TIMEOUT_MS=600000
export BASH_DEFAULT_TIMEOUT_MS=600000
export BASH_MAX_TIMEOUT_MS=600000
export MCP_TIMEOUT=30000
export MCP_TOOL_TIMEOUT=600000
export CLAUDE_API_TIMEOUT=600000

Then reload:

source ~/.zshrc  # or source ~/.bashrc

Troubleshooting

Configuration Not Applied

Problem: Changes to ~/.claude/settings.json don’t take effect

Solutions:

1. Close all Claude Code sessions and open a new terminal
2. Delete ~/.claude/settings.json and reconfigure—Claude Code will generate a new file
3. Validate JSON syntax (check for missing or extra commas)

Invalid API Key

Problem: “API Key invalid or unauthorized” error

Solutions:

• Verify your API key is correct
• Check your account balance at LLMCloud Dashboard

Connection Failed

Problem: Unable to connect to API

Solutions:

• Confirm Base URL is exactly https://llmcloud.studio (no trailing slash, no /v1)
• Check your internet connection

Model Not Found

Problem: “Model not found” error

Solutions:

• Use the exact model ID format (e.g., anthropic/claude-sonnet-4.5-thinking)
• Verify the model is available in your subscription
