Agent Tool Kit Settings

The Settings item opens a modal with workspace-level configuration options.

Timezone & Time Format

Application

Traces older than the configured retention period are automatically and permanently deleted.

AI Assistant

The AI Assistant provides in-product help and analysis features.

The Model Provider and Model Name dropdowns are only active when Enable AI Assistant is turned on. The available options depend on which providers you have configured under Model Providers.

Blocked Endpoints

Use the Blocked Endpoints search field to select API endpoints that should be blocked from receiving traces. This is useful for filtering out health check routes or internal endpoints you don't want to monitor.

Model Providers

Model Providers is a separate page (not inside the Settings modal) where you configure credentials for external LLM providers. Arthur uses these credentials to route evaluation and inference tasks.

Supported providers

• OpenAI (GPT-4, GPT-4o, etc.)
• Anthropic (Claude family)
• Azure OpenAI
• AWS Bedrock
• Google Vertex AI / Gemini
• Custom / self-hosted endpoints

Add a provider

1. Open ⚙ → Model Providers.
2. Click Add Provider.
3. Select your provider from the dropdown.
4. Enter the required credentials (API key, endpoint URL, region, etc.).
5. Click Save. Arthur validates the credential before saving.

Credentials are encrypted at rest. Arthur never exposes stored credentials in plaintext after saving.

Edit or remove a provider

• Click the pencil icon to update credentials.
• Click the trash icon to remove a provider. Any evaluations or AI Assistant configurations that depend on it will stop working — update those first.

API Keys

API Keys is a separate page where you generate and manage personal API keys for programmatic access to the Arthur Engine API and Python SDK.

Generate a new API key

1. Open ⚙ → API Keys.
2. Click Create API Key.
3. Give the key a descriptive name (e.g., local-dev, ci-pipeline).
4. Copy the key immediately — Arthur shows it only once. Store it in a secrets manager or .env file.

Treat your API key like a password. Do not commit it to source control.

Use your API key

from arthur_client import ArthurClient

client = ArthurClient(
    api_key="YOUR_API_KEY",
    base_url="https://your-arthur-instance.com"
)

const response = await fetch("https://your-arthur-instance.com/api/v1/...", {
  method: "GET",
  headers: {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
  }
});
const data = await response.json();

curl -X GET https://your-arthur-instance.com/api/v1/... \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json"

Revoke a key

Click the trash icon next to a key to revoke it. Revocation is immediate — any service using that key loses access instantly. Rotate keys regularly and revoke any that are no longer in use.

Preferences

Preferences controls your personal display theme and does not affect other users in the workspace.
