AnalyticsAPI key9 read, 2 writePro and Team

PostHog syncs a daily product-usage snapshot (event volume by type) — not individual user events. Get a personal API key from PostHog Settings → Personal API Keys. Skills can also query events/persons/insights live and create or update feature flags.

Every PostHog action

Each action is set independently to always allow, ask every time, or disabled. The mode below is the default before anyone changes anything.

Action	What it does	Type	Default
Querymetric.query	Run a live query against a registered GA4/PostHog metric for an exact date range.	read	Always allow
List feature flagsposthog.list_feature_flags	Lists feature flags defined in a PostHog project.	read	Always allow
List insightsposthog.list_insights	Lists insights (funnels, trends, retention, paths) saved in a PostHog project.	read	Always allow
List personsposthog.list_persons	List/search persons (identified users) in a PostHog project.	read	Always allow
List projectsposthog.list_projects	List PostHog projects accessible with this API key. Call this first to discover projectId, which every other PostHog tool requires.	read	Always allow
Query eventsposthog.query_events	Lists raw product analytics events from a PostHog project with optional event-name filtering and pagination.	read	Always allow
Query funnelposthog.query_funnel	Run a sequential-event PostHog funnel query across 2+ event steps.	read	Always allow

Run hogqlposthog.run_hogql	Runs an arbitrary HogQL (SQL) query against a PostHog project and returns the result rows. Flagged sensitive — arbitrary SQL can surface user-identifying data even though this is a read.	sensitive read	Ask every time
Create feature flagposthog.create_feature_flag	Create a new feature flag in a PostHog project.	write	Ask every time
Update feature flagposthog.update_feature_flag	Update an existing feature flag in a PostHog project.	write	Ask every time

Every write stops for a human

Write actions are off entirely until an admin turns them on, and even then each one halts the run and asks before it happens. There is no auto-approve mode anywhere in the product, on any plan. Disabling an action goes further: it is never offered to the model, so it cannot be asked for.
