LangChainToolingConfiguration class
Configuration for LangChain tooling extension package. Inherits all tooling and runtime settings.
Why This Class Exists
Although this class currently adds no new settings beyond what ToolingConfiguration provides, it exists for several important reasons:
Type Safety: Allows LangChain-specific services to declare their dependency on
IConfigurationProvider<LangChainToolingConfiguration>, making the configuration contract explicit and enabling compile-time checking.Extension Point: Provides a clear place to add LangChain-specific settings (e.g., graph execution timeouts, checkpoint intervals, memory limits) without breaking existing code when those needs arise.
Consistent Pattern: Maintains symmetry with other extension packages (Claude, OpenAI), making the SDK easier to understand and navigate.
Dependency Injection: Services can be designed to accept this specific configuration type, enabling proper IoC patterns and testability.
Example
// Service declares explicit dependency on LangChain configuration
class LangChainService {
constructor(private configProvider: IConfigurationProvider<LangChainToolingConfiguration>) {}
}
// Future: Add LangChain-specific settings without breaking changes
class LangChainToolingConfiguration extends ToolingConfiguration {
get graphExecutionTimeout(): number { ... }
}

Properties
| cluster |
|
| is |
Whether the cluster is a development environment (local or dev). Based on clusterCategory. |
| is |
Whether NODE_ENV indicates development mode. Returns true when NODE_ENV is 'development' (case-insensitive). This is the standard Node.js way of indicating development mode. |
| mcp |
Gets the MCP platform authentication scope. Used by AgenticAuthenticationService for token exchange. Trims whitespace to prevent token exchange failures. |
| mcp |
|
| use |
Whether to use the ToolingManifest.json file instead of gateway discovery. Returns true when NODE_ENV is set to 'development' (case-insensitive), or when explicitly overridden via configuration. |
Inherited Methods
| parse |
Parse an environment variable as a boolean. Recognizes 'true', '1', 'yes', 'on' (case-insensitive) as true; all other values as false. |
| parse |
Parse an environment variable as an integer, returning fallback if invalid or not set. |
