Tools for your AI Agents to operate PostHog
Ask your AI agent "Show me all feature flags and which ones are enabled." and get the answer without opening a single dashboard. With 13 tools connected to real PostHog data, your agents reason over live information, cross-reference it with other MCP servers, and deliver insights you would spend hours assembling manually.

Frequently asked questions about the PostHog Alternative MCP Server
How do I create a PostHog Personal API Key?
Log in to PostHog, 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.
