+# OpenID Connect Federated Provider Token Implementation
+
+## Overview
+
+This implementation adds support for passing **federated provider tokens** (Cognito, Azure AD, Auth0, etc.) as variables in LibreChat's `librechat.yaml` configuration for both custom endpoints and MCP servers. These are the actual tokens issued by your federated identity provider, enabling downstream services to validate and authorize users directly.
+
+## Features
+
+### Supported Variables
+
+- `{{LIBRECHAT_OPENID_TOKEN}}` - The current user's access token from federated provider (default)
+- `{{LIBRECHAT_OPENID_ACCESS_TOKEN}}` - Access token specifically from federated provider
+- `{{LIBRECHAT_OPENID_ID_TOKEN}}` - ID token with user claims from federated provider
+- `{{LIBRECHAT_OPENID_USER_ID}}` - User ID from federated provider token (subject claim)
+- `{{LIBRECHAT_OPENID_USER_EMAIL}}` - User email from federated provider token
+- `{{LIBRECHAT_OPENID_USER_NAME}}` - User name from federated provider token
+- `{{LIBRECHAT_OPENID_EXPIRES_AT}}` - Token expiration timestamp
+
+### Usage Examples
+
+#### Custom Endpoints with Cognito
+
+```yaml
+endpoints:
+  custom:
+    - name: 'CognitoProtectedAPI'
+      apiKey: '${API_KEY}'
+      baseURL: 'https://api.example.com'
+      headers:
+        Authorization: 'Bearer {{LIBRECHAT_OPENID_TOKEN}}'
+        X-Cognito-User-ID: '{{LIBRECHAT_OPENID_USER_ID}}'
+        X-User-Email: '{{LIBRECHAT_OPENID_USER_EMAIL}}'
+      models:
+        default: ['gpt-4']
+```
+
+#### MCP Servers with AWS Cognito
+
+```yaml
+mcpServers:
+  aws-cognito-service:
+    command: node
+    args:
+      - server.js
+    env:
+      COGNITO_ACCESS_TOKEN: '{{LIBRECHAT_OPENID_ACCESS_TOKEN}}'
+      COGNITO_ID_TOKEN: '{{LIBRECHAT_OPENID_ID_TOKEN}}'
+      USER_SUB: '{{LIBRECHAT_OPENID_USER_ID}}'
+      USER_EMAIL: '{{LIBRECHAT_OPENID_USER_EMAIL}}'
+
+  cognito-http-service:
+    type: sse
+    url: 'https://mcp.example.com/sse'
+    headers:
+      Authorization: 'Bearer {{LIBRECHAT_OPENID_TOKEN}}'
+      X-Cognito-ID-Token: '{{LIBRECHAT_OPENID_ID_TOKEN}}'
+      X-User-Info: '{{LIBRECHAT_OPENID_USER_EMAIL}}'
+```
+
+#### Azure AD Example
+
+```yaml
+mcpServers:
+  azure-ad-service:
+    command: node
+    args:
+      - azure-server.js
+    env:
+      AZURE_ACCESS_TOKEN: '{{LIBRECHAT_OPENID_ACCESS_TOKEN}}'
+      AZURE_ID_TOKEN: '{{LIBRECHAT_OPENID_ID_TOKEN}}'
+      AAD_USER_OID: '{{LIBRECHAT_OPENID_USER_ID}}'
+```
+
+## Implementation Details
+
+### Architecture
+
+The implementation extends LibreChat's existing template variable system:
+
+1. **OpenID Connect Module** (`packages/api/src/utils/oidc.ts`)
+   - **Federated token extraction** from user session (Cognito, Azure AD, Auth0, etc.)
+   - Token validation and expiration checking
+   - JWT claims parsing for ID tokens
+   - Placeholder processing for federated provider tokens
+   - Security utilities
+
+2. **Integration** (`packages/api/src/utils/env.ts`)
+   - Extended `processSingleValue()` function
+   - OpenID Connect federated provider placeholder resolution
+   - Maintains backward compatibility with existing variables
+
+### Security Features
+
+- **Federated Token Validation**: Checks token expiration before processing
+- **OpenID Connect Availability**: Validates OpenID Connect configuration exists
+- **Secure Processing**: Only processes valid, non-expired federated provider tokens
+- **JWT Claims Parsing**: Safely extracts claims from ID tokens without verification
+- **Error Handling**: Graceful fallbacks for missing or invalid tokens
+- **Provider Agnostic**: Works with Cognito, Azure AD, Auth0, Keycloak, etc.
+
+### Token Flow
+
+1. User authenticates via federated OpenID Connect provider (Cognito, Azure AD, etc.)
+2. **Federated provider tokens** stored in user session/object
+3. Configuration parsing extracts OpenID Connect placeholders
+4. `processSingleValue()` calls federated token processor
+5. Valid federated tokens replace placeholders
+6. **Raw provider tokens** passed to downstream services for validation
+
+## Configuration Requirements
+
+### Environment Variables
+
+OpenID Connect federated provider must be properly configured with:
+
+**For AWS Cognito:**
+```bash
+OPENID_CLIENT_ID=your-cognito-client-id
+OPENID_CLIENT_SECRET=your-cognito-client-secret
+OPENID_ISSUER=https://cognito-idp.region.amazonaws.com/us-east-1_POOL123
+```
+
+**For Azure AD:**
+```bash
+OPENID_CLIENT_ID=your-azure-app-id
+OPENID_CLIENT_SECRET=your-azure-client-secret
+OPENID_ISSUER=https://login.microsoftonline.com/tenant-id/v2.0
+```
+
+**For Auth0:**
+```bash
+OPENID_CLIENT_ID=your-auth0-client-id
+OPENID_CLIENT_SECRET=your-auth0-client-secret
+OPENID_ISSUER=https://your-domain.auth0.com/
+```
+
+### LibreChat Configuration
+
+Enable OIDC in your LibreChat registration:
+
+```yaml
+registration:
+  socialLogins: ['openid']
+```
+
+## Security Considerations
+
+### Federated Token Security
+
+- **Server-side Processing**: Federated provider tokens are only processed server-side
+- **Expiration Validation**: Expired tokens are automatically rejected
+- **No Client Exposure**: Tokens never stored in client-side configuration
+- **Pre-validation**: Tokens validated before each use
+- **JWT Claims**: ID token claims safely extracted without verification
+
+### Best Practices
+
+1. **Use HTTPS**: Always use HTTPS for downstream services receiving tokens
+2. **Token Scopes**: Ensure federated provider tokens have appropriate scopes
+3. **Token Validation**: Downstream services should validate received federated tokens
+4. **Expiration Monitoring**: Monitor token expiration and refresh cycles
+5. **Provider-Specific**: Configure according to your federated provider (Cognito, Azure AD, etc.)
+
+### Federated Provider Considerations
+
+**AWS Cognito:**
+- Use `sub` claim for user identification
+- Validate tokens against Cognito User Pool
+- Consider token refresh for long-running sessions
+
+**Azure AD:**
+- Use `oid` or `sub` claim for user identification
+- Validate tokens against Azure AD tenant
+- Configure appropriate scopes (openid, profile, email)
+
+**Auth0:**
+- Use `sub` claim for user identification
+- Validate tokens against Auth0 domain
+- Configure custom claims as needed
+
+### Risk Mitigation
+
+- **No Token Exposure**: Tokens never appear in logs or client responses
+- **Validation Layer**: Multi-level validation prevents invalid token usage
+- **Graceful Degradation**: System continues working if OIDC unavailable
+- **Error Isolation**: OIDC failures don't break other functionality
+
+## Testing
+
+Comprehensive test suite covers:
+
+- **Federated token extraction** from multiple storage locations
+- **JWT claims parsing** from ID tokens
+- **Provider-specific scenarios** (Cognito, Azure AD examples)
+- Placeholder processing for all variable types
+- Integration with existing LibreChat systems
+- Security edge cases and error handling
+- Token expiration and validation scenarios
+
+Run tests:
+```bash
+npm test -- src/tests/oidc-integration.test.ts
+```
+
+## Migration Guide
+
+### Existing Deployments
+
+1. **Update Code**: Apply the implementation changes
+2. **Configure Federated Provider**: Set up OpenID Connect environment variables for your provider (Cognito, Azure AD, etc.)
+3. **Update Config**: Add OpenID Connect variables to librechat.yaml
+4. **Verify Token Storage**: Ensure federated provider tokens are stored in user session
+5. **Test Integration**: Verify downstream services receive and validate federated provider tokens
+6. **Monitor**: Check logs for any integration issues
+
+### Backward Compatibility
+
+- Existing configurations continue working unchanged
+- New OpenID Connect variables are additive, not replacing existing functionality
+- Non-OpenID Connect users see no functional changes
+- All existing template variables remain supported
+- Works alongside current `{{LIBRECHAT_USER_*}}` and `{{LIBRECHAT_BODY_*}}` variables
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Empty Token Values**
+   - Check OpenID Connect federated provider configuration
+   - Verify user authenticated via federated provider (not local auth)
+   - Confirm federated tokens stored in user session
+   - Check token not expired
+
+2. **Authentication Failures**
+   - Validate downstream service expects federated provider tokens
+   - Verify downstream service configured to validate against your provider
+   - Check token scopes and permissions from federated provider
+   - Verify HTTPS endpoints
+
+3. **Variable Not Replaced**
+   - Confirm user authenticated via OpenID Connect (not Google, Facebook, etc.)
+   - Check federated token validity and expiration
+   - Verify placeholder syntax uses `OPENID` not `OIDC`
+   - Ensure tokens stored in `federatedTokens` or `openidTokens`
+
+### Debug Steps
+
+1. Check LibreChat logs for OpenID Connect errors
+2. Verify federated provider environment variables set correctly
+3. Test OpenID Connect authentication flow
+4. Confirm federated tokens are stored in user session
+5. Validate downstream service configuration for your provider
+6. Monitor federated token expiration times
+7. Test token validation with your federated provider's validation endpoint
+
+## Future Enhancements
+
+### Potential Improvements
+
+1. **Token Refresh**: Automatic token refresh handling
+2. **Scope Validation**: Verify token scopes match requirements
+3. **Multi-Provider**: Support multiple OIDC providers
+4. **Token Claims**: Access to specific JWT claims
+5. **Caching**: Token caching for performance optimization
+
+### Integration Opportunities
+
+- Integration with existing session management
+- Enhanced MCP server authentication
+- Custom endpoint security improvements
+- Audit logging for token usage
+- Advanced claim-based authorization
+
