1. Add the server

Run in your terminal

gemini mcp add --transport http posthog https://mcp.posthog.com/mcp

2. Sign in

Run /mcp auth <name> inside Gemini CLI to sign in to an OAuth server. PostHog is hosted by PostHog, so there is nothing to install or keep updated.

3. Try it

Ask Gemini CLI for something PostHog can do. Query product analytics, manage feature flags and experiments, and inspect errors. Approve the first tool call and check the result before allowing write actions automatically.

· In settings.json, streamable HTTP servers use httpUrl, SSE servers use url, local servers use command.
· includeTools and excludeTools limit which tools the model sees.
