Best When

An agent needs to query or manage Unleash feature flags — especially for automated release management, incident response, or progressive delivery.

Avoid When

You're using LaunchDarkly, Split.io, or another feature flag platform.

Use Cases

  • Querying feature flag states from release management agents
  • Creating and updating feature toggles from deployment automation agents
  • Managing gradual rollout percentages from progressive delivery agents
  • Disabling features for incident response from on-call agents
  • Auditing feature flag configurations from compliance agents
  • Coordinating feature releases across environments from CI/CD agents

Not For

  • Teams using LaunchDarkly, Split.io, or Statsig for feature management
  • A/B testing at statistical significance scale (use dedicated experimentation platforms)
  • Teams without Unleash deployment

Known Gotchas

  • Admin API token vs Client SDK token are different — use Admin token for management operations
  • Unleash projects contain feature flags — must specify correct project context
  • Environment-specific flag states — production vs staging have separate configurations
  • Strategy evaluation happens client-side — MCP server manages configuration, not evaluation
  • Self-hosted vs Cloud Unleash have same API but different base URLs
  • Variants and custom strategies require understanding Unleash data model
