Use the PostHog MCP server
in ChatGPT

Query analytics, insights, and feature flags in PostHog. This guide connects PostHog to ChatGPT (chatgpt.com) through a governed gateway — one URL that also works in every other MCP client you use, with your rules and a full log attached.

Live-probed · Security-scanned · OAuth sign-in

Setup: PostHog in ChatGPT

ChatGPT adds MCP servers via custom connectors in developer mode. The gateway route takes about two minutes:

  1. Connect PostHog to your free gate gateway from the verified directory.
  2. Open ChatGPT → Settings → Connectors and enable Developer mode under Advanced.
  3. Click 'Create', name it 'gate', paste your gateway URL, and set authentication to OAuth.
  4. Approve the authorization — PostHog is now available in your ChatGPT conversations.

What to ask once it’s connected

“How did signups trend this week?”
“Which feature flags are currently active?”
“Show the funnel from landing page to signup.”
“Which pages convert best?”

Why route it through a gateway

One URL, every client

The same PostHog connection works in Claude, Claude Code, Cursor, VS Code too — no per-client re-wiring.

Rules before regret

Allow, ask, or block every tool PostHog exposes — reads can flow freely while writes require your approval.

Every call logged

A plain-language activity log of everything ChatGPT did with PostHog — searchable, exportable, auditable.

Scanned and probed

PostHog passed a live handshake probe and a security scan before listing — and drift detection watches it after you connect.
