MCP · PostHog — product analytics in plain language

Use case: funnels, usage trends, feature flags — product questions asked in plain language, the answers landing in the sprint-review note.

Configuration (.znote/mcp.json)

{
  "mcpServers": {
    "posthog": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.posthog.com/mcp"],

    }
  }

Official remote server. Authentication via a personal API key (PostHog → Settings → Personal API keys), passed as a header with mcp-remote --header "Authorization: Bearer phx_..." when OAuth isn't offered on your instance.

Exposed tools: insights-get-all, query-run, dashboards-get-all, feature-flag-get-all, error-tracking-list, experiments-get-all…

Examples

Sprint review

Over the last 14 days: active-user trend, top 5 events, and the
signup → first_project → first_export funnel. Where do we lose the
most people?

Check a launch

The "dark-mode" feature shipped two weeks ago. How many users triggered
the dark_mode_enabled event, and does that segment's D7 retention
differ from the rest?

Flag cleanup

List the feature flags at 100% rollout for more than 30 days —
candidates for removal from the code.

Tips

• The numbers persisted in the note = the sprint recap writes itself.
• Cross with Stripe: "do paying users use the export feature more than free users?"
