Claude Code

Wire Anthropic's terminal coding agent to Prismma with three env vars.

Connect

Claude Code reads ANTHROPIC_BASE_URL and ANTHROPIC_AUTH_TOKEN on startup. Point the base URL at Prismma's root and the token at your sk-eu-... key.

shell

# Connect Claude Code → Prismma
unset ANTHROPIC_API_KEY   # Claude Code v2.x prefers this over ANTHROPIC_AUTH_TOKEN
export ANTHROPIC_BASE_URL="https://api.prismma.ai"
export ANTHROPIC_AUTH_TOKEN="sk-eu-YOUR-KEY"
export ANTHROPIC_MODEL="claude-opus-4-7"

claude

Alternative: ~/.claude/settings.json

~/.claude/settings.json

// ~/.claude/settings.json
{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.prismma.ai",
    "ANTHROPIC_AUTH_TOKEN": "sk-eu-YOUR-KEY",
    "ANTHROPIC_MODEL": "claude-opus-4-7",
    "ANTHROPIC_API_KEY": ""
  }
}

The API-key gotcha

Claude Code v2.x prefers ANTHROPIC_API_KEY over ANTHROPIC_AUTH_TOKEN when both are set. If a stale ANTHROPIC_API_KEY is exported in your shell, your Prismma key is ignored and requests go directly to api.anthropic.com, failing with "Invalid API key." Always unset ANTHROPIC_API_KEY (or set it to an empty string in settings.json) before using ANTHROPIC_AUTH_TOKEN.

For real 1M-token context on Claude models, also set ANTHROPIC_BETAS=context-1m-2025-08-07 — see 1M Context (Claude).
