update-rollout
Change the default rule (fallthrough) for a flag. Set a percentage rollout across variations or serve a single variation to all unmatched users. Weights must sum to 100. Use human-friendly percentages (e.g., 80 for 80%).
toggle-flag
Turn a feature flag's targeting on or off in a specific environment. Returns the previous and new state. If the environment requires approval, the response will include requiresApproval: true and an approvalUrl instead of executing.
update-flag-settings
Update a flag's top-level settings: name, description, tags, temporary/permanent status, or maintainer. Does NOT modify targeting, rollouts, or rules: use the targeting tools for those. Supported instruction kinds: updateName, updateDescription, addTags, removeTags, markTemporary, markPermanent, updateMaintainerMember.
create-flag
Create a new feature flag in a project. Defaults to a boolean temporary flag. After creation the flag is OFF in all environments: use toggle-flag to enable it. For multivariate flags, provide variations array with {value, name} entries.
get-flag-status-across-envs
Check a flag's lifecycle status across all environments. Returns per-environment state (active, inactive, new, launched) and a summary of which environments the flag is active, inactive, or launched in. Use before cleanup to verify the flag is inactive everywhere.
find-stale-flags
Find feature flags that are candidates for cleanup. Returns a prioritized list of stale flags sorted by staleness (worst first). Categories: inactive_30d (no requests in period), launched_no_changes (fully rolled out, no recent changes), never_requested (created but never evaluated). Defaults to showing temporary flags inactive for 30+ days.
get-flag-health
Get combined health view for a single flag: lifecycle state, last-requested timestamp, targeting summary (rules count, targets count, on/off), age, and whether it's temporary. Use this to assess if a flag is stale or needs attention.
get-flag
Get detailed configuration for a single feature flag scoped to a specific environment. Returns the full targeting tree including rules, individual targets, fallthrough, prerequisites, and variation details.
list-flags
Search and browse feature flags in a project. Returns a paginated list scoped to a single environment. Use query to search by name/key, tags to filter by tag, state to filter by lifecycle state (active, inactive, new, launched, archived), and type to filter by temporary or permanent.
