Authentication

The Redis Agent Memory Server supports multiple authentication modes for secure API access. All API endpoints (except /health, /docs, and /openapi.json) require valid authentication unless disabled for development.

Authentication Modes

The server supports three authentication modes:

  1. Disabled (default): No authentication required - suitable for development only
  2. Token Authentication: Simple API tokens stored in Redis with optional expiration
  3. OAuth2/JWT: Industry-standard authentication using JWT access tokens

Features

  • Simple Token Authentication: Generate and manage API tokens via CLI with optional expiration
  • OAuth2/JWT Bearer Token Authentication: Industry-standard authentication using JWT access tokens
  • JWKS Public Key Validation: Automatic fetching and caching of public keys for token signature verification
  • Multi-Provider Support: Compatible with Auth0, AWS Cognito, Okta, Azure AD, and any standard OAuth2 provider
  • Flexible Configuration: Environment variable-based configuration for different deployment scenarios
  • Development Mode: DISABLE_AUTH setting for local development and testing
  • Role and Scope Support: Fine-grained access control using JWT claims
  • CLI Token Management: Create, list, view, and remove tokens via command line

Configuration

Basic Configuration

Authentication is configured using environment variables:

# Authentication Mode Selection
AUTH_MODE=disabled  # Options: disabled, token, oauth2 (default: disabled)
# OR legacy setting:
DISABLE_AUTH=true   # Set to true to bypass all authentication (development only)

# Token Authentication (when AUTH_MODE=token)
TOKEN_AUTH_ENABLED=true  # Alternative way to enable token auth

# OAuth2 Provider Configuration (when AUTH_MODE=oauth2)
OAUTH2_ISSUER_URL=https://your-auth-provider.com
OAUTH2_AUDIENCE=your-api-audience
OAUTH2_JWKS_URL=https://your-auth-provider.com/.well-known/jwks.json  # Optional, auto-derived from issuer
OAUTH2_ALGORITHMS=["RS256"]  # Supported signing algorithms

Token Authentication Setup

To use token authentication:

  1. Enable token authentication: 

    export AUTH_MODE=token
# OR
export TOKEN_AUTH_ENABLED=true

  2. Create tokens using the CLI: 

    # Create a token with 30-day expiration
uv run agent-memory token add --description "API access token" --expires-days 30

# Create a permanent token (no expiration)
uv run agent-memory token add --description "Service account token"

  3. Use the token in API requests: 

    curl -H "Authorization: Bearer YOUR_TOKEN" \
     http://localhost:8000/v1/working-memory/

Token Management Commands

The CLI provides comprehensive token management:

# List all tokens (shows masked token hashes)
uv run agent-memory token list

# Show details for a specific token (supports partial hash matching)
uv run agent-memory token show abc12345

# Remove a token (with confirmation)
uv run agent-memory token remove abc12345

# Remove a token without confirmation
uv run agent-memory token remove abc12345 --force

Security Features: - Tokens are hashed using bcrypt before storage - Only hashed values are stored in Redis (server never has access to plaintext tokens) - Automatic expiration using Redis TTL - Secure token generation using secrets.token_urlsafe()

OAuth2 Provider Examples

Auth0

OAUTH2_ISSUER_URL=https://your-domain.auth0.com/
OAUTH2_AUDIENCE=https://your-api.com

AWS Cognito

OAUTH2_ISSUER_URL=https://cognito-idp.region.amazonaws.com/your-user-pool-id
OAUTH2_AUDIENCE=your-app-client-id

Okta

OAUTH2_ISSUER_URL=https://your-domain.okta.com/oauth2/default
OAUTH2_AUDIENCE=api://default

Azure AD

OAUTH2_ISSUER_URL=https://login.microsoftonline.com/your-tenant-id/v2.0
OAUTH2_AUDIENCE=your-application-id

Usage Examples

With Token Authentication

# First, create a token
uv run agent-memory token add --description "My API token" --expires-days 30

# Use the returned token in API requests
curl -H "Authorization: Bearer YOUR_API_TOKEN" \
     -H "Content-Type: application/json" \
     http://localhost:8000/v1/working-memory/

# Python example
import httpx

headers = {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json"
}

response = httpx.get("http://localhost:8000/v1/working-memory/", headers=headers)

With OAuth2/JWT Authentication

# Make authenticated API request with JWT
curl -H "Authorization: Bearer YOUR_JWT_TOKEN" \
     -H "Content-Type: application/json" \
     http://localhost:8000/v1/working-memory/

# Python example
import httpx

headers = {
    "Authorization": "Bearer YOUR_JWT_TOKEN",
    "Content-Type": "application/json"
}

response = httpx.get("http://localhost:8000/v1/working-memory/", headers=headers)

Development Mode (Local Testing)

# Set environment variable to disable auth
export DISABLE_AUTH=true

# Now you can make requests without tokens
curl -H "Content-Type: application/json" \
     http://localhost:8000/v1/working-memory/

Token Requirements

API Tokens (Token Authentication)

  • Valid token: Must exist in Redis and not be expired
  • Secure generation: Generated using cryptographically secure random bytes
  • Optional expiration: Tokens can be created with or without expiration dates

JWT Tokens (OAuth2 Authentication)

JWT tokens must include:

  • Valid signature: Verified using JWKS public keys from the issuer
  • Not expired: exp claim must be in the future
  • Valid audience: aud claim must match OAUTH2_AUDIENCE (if configured)
  • Valid issuer: iss claim must match OAUTH2_ISSUER_URL
  • Subject: sub claim identifying the user/client

Error Responses

Authentication failures return HTTP 401 with details:

{
  "detail": "Invalid JWT: Token has expired",
  "status_code": 401
}

Common error scenarios:

General Authentication Errors: - Missing authorization header: No Authorization: Bearer header provided - Missing bearer token: Empty or malformed authorization header

Token Authentication Errors: - Invalid token: Token not found in Redis or malformed - Token has expired: Token expiration date has passed

OAuth2/JWT Authentication Errors: - Invalid token header: Malformed JWT structure - Token has expired: JWT exp claim is in the past - Invalid audience: JWT aud claim doesn't match expected audience - Unable to find matching public key: JWKS doesn't contain key for token's kid

Security Best Practices

General Security

  1. Never use DISABLE_AUTH=true in production
  2. Use HTTPS in production to protect tokens in transit
  3. Monitor authentication failures and implement rate limiting if needed
  4. Handle 401 responses appropriately in your clients
  5. Validate tokens server-side - never trust client-side validation alone

Token Authentication Security

  1. Use token expiration when creating tokens for enhanced security
  2. Rotate tokens regularly by removing old tokens and creating new ones
  3. Store tokens securely in your applications (use environment variables, not code)
  4. Remove unused tokens using the CLI to minimize attack surface
  5. Monitor token usage and remove tokens that are no longer needed

OAuth2/JWT Security

  1. Implement token refresh in your clients for long-running applications
  2. Use appropriate scopes/roles for fine-grained access control
  3. Validate token expiration and audience claims properly
  4. Cache JWKS appropriately but refresh periodically
