PostHog MCP server

This is the official helper from PostHog, the tool many teams use to see how people use their product. Once it is connected, your AI can look at your PostHog numbers and settings for you, and even make changes when you ask. It is handy if you work with product data, feature flags or error reports and want answers without clicking around the PostHog website.

What this MCP server does

You ask your AI a question in normal words, like how many people signed up last week. The AI passes that request to this helper, which talks to your PostHog account. PostHog sends back the numbers or the settings, and the helper hands them to your AI. Your AI then explains the answer to you in the chat, as a table, a list or a short summary.

Try asking your AI

• “How many unique users signed up in the last 7 days, broken down by day?”
• “Create a feature flag called new-checkout-flow that is on for 20% of users”
• “What are the top 5 errors in my project this week and how many users are affected?”
• “List my dashboards and tell me what is on the busiest one”

What it gives back to you

You get answers in the chat: tables of numbers, lists of flags or dashboards, short summaries of what changed, and links back to the right page in PostHog. When you ask it to create or change something, it tells you what it did, like the flag key and the rollout percentage. It also gives you a link so you can check the result yourself.
