NuGet Packages

Fig provides several NuGet packages for different integration scenarios.

Core

Fig.Client

The main client library. Add this to applications whose settings Fig should manage.

• Target framework: .NET Standard 2.0
• Documentation: Client Configuration

Fig.Client.Abstractions

Attributes and contracts so third-party libraries can declare Fig settings without taking a dependency on the full client.

• Target framework: .NET Standard 2.0

Fig.Client.Contracts

Internal contracts, including IClientSecretProvider. Most applications do not reference this directly unless they write a custom secret provider.

Fig.WebHooks.Contracts

Data contracts for webhook payloads. Use this when building a webhook integration.

Secret providers

Each provider is a separate package. See Client Secrets.

Package	Documentation
Fig.Client.SecretProvider.Docker	Docker
Fig.Client.SecretProvider.Dpapi	DPAPI (Windows)
Fig.Client.SecretProvider.Azure	Azure Key Vault client secret
Fig.Client.SecretProvider.Aws	AWS Secrets Manager
Fig.Client.SecretProvider.Google	Google Cloud Secret Manager

Azure Key Vault can also store setting values on the API (a different feature). See Azure Key Vault Integration.

Testing and hosting

Fig.Client.Testing

Reloadable configuration for integration tests, plus display-script testing helpers. See Integration Testing and Settings Binding Verification.

Fig.Aspire

AppHost extension methods (AddFigApi, AddFigWeb). See .NET Aspire Integration.

Not a NuGet package

Fig MCP is a standalone application / container that proxies MCP tools to the Fig API. See Fig MCP Server.
