Mistral Enterprise Rbac

Mistral AI Enterprise RBAC

Overview

Control access to Mistral AI at the organization level using La Plateforme workspace management: scoped API keys per team, model access restrictions, spending limits, key auditing, and automated rotation. Mistral organizes access via Organizations > Workspaces > API Keys, with rate limits set at the workspace level.

Prerequisites

• Mistral La Plateforme organization account (console.mistral.ai)
• Organization admin or owner role
• Understanding of workspace vs key-level controls

Instructions

Step 1: Workspace Strategy

Create workspaces via La Plateforme console: Organization > Workspaces > Create.

Step 2: Scoped API Keys per Team

Create keys with model restrictions and rate limits in the console, or via API:

set -euo pipefail
# Dev team — restricted to cost-effective models
curl -X POST https://api.mistral.ai/v1/api-keys \
  -H "Authorization: Bearer $MISTRAL_ADMIN_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "dev-team-key",
    "description": "Dev team — small models only",
    "workspace_id": "ws_dev_xxx"
  }'

# ML team — full model access
curl -X POST https://api.mistral.ai/v1/api-keys \
  -H "Authorization: Bearer $MISTRAL_ADMIN_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "ml-team-key",
    "description": "ML team — all models",
    "workspace_id": "ws_ml_xxx"
  }'

Step 3: Application-Level Model Gateway

Enforce model access in your application layer:

const ROLE_PERMISSIONS: Record<string, {
  allowedModels: string[];
  maxTokensPerRequest: number;
  dailyTokenBudget: number;
}> = {
  analyst: {
    allowedModels: ['mistral-small-latest', 'mistral-embed'],
    maxTokensPerRequest: 500,
    dailyTokenBudget: 100_000,
  },
  developer: {
    allowedModels: ['mistral-small-latest', 'codestral-latest', 'mistral-embed'],
    maxTokensPerRequest: 2000,
    dailyTokenBudget: 500_000,
  },
  senior: {
    allowedModels: ['mistral-small-latest', 'mistral-large-latest', 'codestral-latest', 'mistral-embed'],
    maxTokensPerRequest: 4000,
    dailyTokenBudget: 1_000_000,
  },
  admin: {
    allowedModels: ['*'],
    maxTokensPerRequest: 8000,
    dailyTokenBudget: Infinity,
  },
};

function authorizeRequest(role: string, model: string, estimatedTokens: number): boolean {
  const perms = ROLE_PERMISSIONS[role];
  if (!perms) return false;

  const modelAllowed = perms.allowedModels.includes('*') || perms.allowedModels.includes(model);
  const tokensAllowed = estimatedTokens <= perms.maxTokensPerRequest;

  return modelAllowed && tokensAllowed;
}

Step 4: Spending Limits

Configure in La Plateforme console: Organization > Billing > Budget Alerts.

// Application-level budget enforcement
class SpendingGuard {
  private hourlySpend = 0;
  private hourStart = Date.now();
  private readonly maxHourlyUsd: number;

  constructor(maxHourlyUsd: number) {
    this.maxHourlyUsd = maxHourlyUsd;
  }

  recordCost(costUsd: number): void {
    if (Date.now() - this.hourStart > 3_600_000) {
      this.hourlySpend = 0;
      this.hourStart = Date.now();
    }
    this.hourlySpend += costUsd;
  }

  canSpend(estimatedCostUsd: number): boolean {
    return this.hourlySpend + estimatedCostUsd <= this.maxHourlyUsd;
  }
}

Step 5: Key Audit

set -euo pipefail
# List all API keys with metadata
curl -s https://api.mistral.ai/v1/api-keys \
  -H "Authorization: Bearer $MISTRAL_ADMIN_KEY" | \
  jq '.data[] | {name, id, created_at, last_used_at}'

# Identify unused keys (not used in 30+ days)
curl -s https://api.mistral.ai/v1/api-keys \
  -H "Authorization: Bearer $MISTRAL_ADMIN_KEY" | \
  jq '.data[] | select(.last_used_at < (now - 2592000 | todate)) | {name, id, last_used_at}'

Step 6: Automated Key Rotation

// Rotate keys on a 90-day schedule
async function rotateApiKey(oldKeyId: string, keyName: string): Promise<string> {
  // 1. Create new key
  const newKey = await createApiKey({ name: `${keyName}-${Date.now()}` });

  // 2. Update consuming services (secret manager)
  await updateSecret('mistral-api-key', newKey.apiKey);

  // 3. Wait for propagation (services pick up new secret)
  await new Promise(r => setTimeout(r, 60_000));

  // 4. Verify new key works
  const client = new Mistral({ apiKey: newKey.apiKey });
  await client.models.list(); // throws if invalid

  // 5. Revoke old key
  await revokeApiKey(oldKeyId);

  console.log(`Rotated key: ${keyName} (old: ${oldKeyId}, new: ${newKey.id})`);
  return newKey.id;
}
