Anthropic Enterprise RBAC

Overview

Anthropic provides organization-level access control through Workspaces, API key scoping, and member roles via the Console at console.anthropic.com.

Application-Level RBAC

# Implement your own RBAC on top of Anthropic Workspaces
from enum import Enum
import anthropic

class UserRole(Enum):
    VIEWER = "viewer"       # Can read Claude responses (no direct API)
    USER = "user"           # Can send prompts (rate limited)
    POWER_USER = "power"    # Can use Opus, higher limits
    ADMIN = "admin"         # Can access all models, no limits

ROLE_CONFIG = {
    UserRole.VIEWER: {"allowed": False},
    UserRole.USER: {
        "allowed": True,
        "models": ["claude-haiku-4-20250514"],
        "max_tokens": 512,
        "rpm_limit": 10,
    },
    UserRole.POWER_USER: {
        "allowed": True,
        "models": ["claude-haiku-4-20250514", "claude-sonnet-4-20250514", "claude-opus-4-20250514"],
        "max_tokens": 4096,
        "rpm_limit": 60,
    },
    UserRole.ADMIN: {
        "allowed": True,
        "models": ["claude-haiku-4-20250514", "claude-sonnet-4-20250514", "claude-opus-4-20250514"],
        "max_tokens": 8192,

    config = ROLE_CONFIG[user_role]
    if not config["allowed"]:
        raise PermissionError("Role does not allow API access")
    if model not in config["models"]:
        raise PermissionError(f"Role cannot access model: {model}")
    kwargs["max_tokens"] = min(kwargs.get("max_tokens", 1024), config["max_tokens"])

Key Management Best Practices

Practice	Implementation
One key per service	prod-auth-service, prod-search-service
Rotate quarterly	Calendar reminder + automated rotation
Least privilege	Dev workspace for dev keys only
Audit trail	Log which key made each request
Revoke immediately	On employee departure or compromise

Error Handling

Issue	Cause	Fix
Key works in dev, fails in prod	Wrong workspace key	Verify key belongs to prod workspace
New team member can't access	Not added to workspace	Invite via Console > Members
Usage not visible	Viewing wrong workspace	Switch workspace in Console
