Check Feature Flags for Context

The `get_client_features` tool fetches all active feature flags and strategies. You pass context like a user ID or specific properties to evaluate the correct flag state. This means you can test how different users see the product—whether they're in beta, on enterprise plans, or using certain features—before deploying changes.

Track Usage Metrics

Need to know if your feature flags are actually doing anything? Call `report_client_metrics` or `report_frontend_metrics`. These tools send usage data back to Unleash. This lets you monitor which features people use and how often, so you can prove the value of a toggle.

List Projects and Environments

The `list_projects` tool fetches every project configured in your account. It also gives you access to all environments via `list_environments`. You can confirm which projects exist, or see if a specific environment (like 'staging' vs. 'production') is set up before running any flag checks.
