Read Your PostHog Product Analytics Through Your Muse

Through a custom connector, your muse can answer product questions from your PostHog data in plain words: count visitors and events, compute funnel and retention rates, read saved charts, and check feature flags and experiments.

What it does

The connector adds 28 tools. It can run one read-only query at a time over your events, persons, sessions, and groups, and calculate trends, funnels, retention, stickiness, lifecycle, and paths. It can search persons, read one, and list cohorts and experiments. It can list saved insights and dashboards, read one dashboard with its tiles, and save or change an insight. It can list feature flags with rollout percentages, read one flag, and, with your confirmation, create or change a flag. It can list annotations on your charts and add one.

How to use it

1. Start an AnythingMCP account and add the PostHog connector.
2. In PostHog, open Settings, then User, then Personal API keys, and create a key. Pick the projects it may reach, and copy it at once, because PostHog shows it only once.
3. Set the host to your PostHog address, US Cloud, EU Cloud, or self-hosted. A key only works in the region where it was created.
4. Enter the host and key only where the connector asks. For a read-only setup, give the key only read scopes.
5. In Muse, open Settings, then Connectors, and add a custom connector with the address AnythingMCP gives you. Sign in and approve.
6. Start with a read: ask which project the key sees, then a count from last week, and check it in PostHog.

What you need

• A Muse account that can add custom connectors
• An AnythingMCP account with the PostHog connector added
• A PostHog account, and a personal API key scoped to the projects you want to share

What to watch for

• Feature flags decide what live users see. Before a flag changes, the muse shows its key, state, and rollout, and waits for your yes. A new flag is safest off.
• Three delete tools start off. PostHog only marks items deleted, so they can be restored, but a deleted flag is off for everyone.
• Queries need a time filter. An unfiltered scan is slow and uses the shared read budget.
• Use the project number from the PostHog address, not the last opened project. The connector does not capture events or read session replays or surveys.
• This is a custom connector, and Meta does not review custom connectors. You can disconnect it in Settings at any time. The muse prepares, you decide.
