Tools 7

Tool	Type	What it does
`hypertune_evaluate`	read	Evaluate Evaluate one or more feature flags for a given context — environment plus user and request attributes — and get their fully resolved JSON values back.
`hypertune_get_logic`	read	Get logic Fetch the underlying conditional expression and targeting rules of flags without reducing them, so you can inspect exactly how a flag is configured.
`hypertune_list_flags`	read	List flags List the project's top-level feature flags with their return types and descriptions — a convenient first call to discover what flags exist before evaluating.
`hypertune_introspect`	read	Introspect Run a GraphQL introspection query to discover the project's full schema, including every available flag and the exact shape of the evaluation context.
`hypertune_query`	read	Query Run an arbitrary GraphQL query with optional variables against the Hypertune edge endpoint — a power-user escape hatch for any flag shape or nested selection.
`hypertune_usage_status`	meta	Usage status (free-tier meter) Report the caller's current free-tier usage this month: calls used, monthly limit, remaining, and whether the cap is reached. Read-only; does not count against the meter.
`hypertune_upgrade`	meta	Upgrade to Pro (unlimited) Subscribe to the Pro plan for UNLIMITED Hypertune tool calls (the free tier caps monthly usage). Choose monthly ($9/month) or yearly ($90/year — 2 months free) billing. Returns a Stripe Checkout link to open in your browser; after payment your account upgrades automatically. Read-only; does not count against the meter.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
