How do I create a PostHog Personal API Key?

Log in to [**PostHog**](https://app.posthog.com), click your profile icon > **Personal API keys**, then **+ Create a Personal API Key**. Give it a label, select the required scopes and copy the key immediately — it won't be shown again after page refresh.

Can I toggle feature flags via the agent?

Yes! Use `create_feature_flag` to add new flags, `update_feature_flag` to modify existing ones (name, description, enabled status), and `delete_feature_flag` to remove them. You'll need the numeric flag ID from `list_feature_flags` for update and delete operations.

What's the difference between events and persons?

**Events** are actions that happen in your product (pageviews, button clicks, purchases). **Persons** are the users who perform those actions, identified by distinct_id. Events are linked to persons, so you can see what actions a specific user has taken. Use `list_events` to browse activity and `get_person` to see a user's profile.

Can I use this with a self-hosted PostHog instance?

Yes! The tools default to `https://app.posthog.com` for the US cloud, but you can set the `host` parameter to your self-hosted instance URL (e.g. `https://posthog.yourcompany.com`). EU cloud users should set the host to `https://eu.posthog.com`.
