How to Connect PostHog to ChatGPT
Query your PostHog data directly from ChatGPT using Sequel’s MCP server. Ask questions in plain English, with no SQL, no dashboards, and no context switching.
Short answer
Connect PostHog to Sequel, then add Sequel's MCP server to ChatGPT using the config on this page. ChatGPT can then query your live PostHog data in plain English, with no connector code and no CSV exports. Both steps take a few minutes.
Everything you can ask ChatGPT about your PostHog data.
Ask in plain English — Sequel translates it into a PostHog query, runs it, and ChatGPT hands back the answer. No SQL, no dashboards, no CSV exports.
- How many unique users triggered $pageview yesterday, by country?
- Show me the signup → activation funnel for users created in the last 30 days.
- What's the 7-day retention of users in the 'Power users' cohort?
- Which 10 feature flags have the most evaluations this week?
- Compare conversion rate by browser for the checkout funnel.
How it works
Three steps to get started
Connect PostHog to Sequel
In your Sequel dashboard, go to Connections and add PostHog. Sequel handles authentication and schema discovery automatically.
Add Sequel to the agent
Copy the Sequel MCP configuration into ChatGPT's settings file (shown below). Swap in your API key from Settings → API Keys.
Ask ChatGPT about your data
Restart ChatGPT and start asking questions. "How many unique users triggered $pageview yesterday, by country?" — and get a real answer backed by live PostHog data.
Why ChatGPT
What ChatGPT does with your PostHog data
Real data, not hallucinations
ChatGPT with Sequel queries your actual databases in real time. Instead of guessing or making up numbers, it fetches accurate data from your connected sources and presents verified results.
Share data insights via ChatGPT conversations
Teams that already use ChatGPT for work can now use it for data questions too. Sequel handles the database access; ChatGPT handles the explanation and formatting.
Analyze data with Python in the same thread
When SQL isn't enough, Sequel's workbench tool lets ChatGPT run Python analyses — statistical summaries, charts, transformations — without leaving the conversation.
Configuration
Add Sequel to ChatGPT
Place this in ChatGPT Settings → Connectors and replace sql_your_api_key with a key from Settings → API Keys.
ChatGPT Settings → Connectors
Server URL: https://api.sequel.sh/mcp Authentication: Authorization: Bearer sql_your_api_key
Install
Install PostHog MCP in ChatGPT
Pick your app and Sequel installs itself: a one-click link where the client supports it, that client’s own few steps where it doesn’t. Every route signs in with your Sequel account over OAuth, so there is no API key to copy and nothing to keep in sync.
Already have an MCP client?
https://api.sequel.sh/mcp
Add it as a remote (streamable HTTP) server and sign in when prompted. Skills come with it; nothing else to install. Manual setup per client

Frequently asked questions
How do I connect PostHog to ChatGPT?
You need two things: (1) connect PostHog to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to ChatGPT using the setup shown above. Once both are done, ChatGPT can query your PostHog data directly.
What PostHog data can ChatGPT access?
ChatGPT can access any data available through your PostHog connection in Sequel. Use Sequel's search tool to discover available metrics and dimensions, then execute queries to pull the data you need.
Is my PostHog data sent to ChatGPT's servers?
Query results are returned to ChatGPT as context within your conversation. Only the data you explicitly ask about is retrieved. Sequel never stores your query results permanently — they exist only for the duration of the tool call.
Do I need a Sequel account?
Yes. You need a Sequel account to connect PostHog and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to PostHog and generate an API key from Settings → API Keys.
Can I connect multiple PostHog accounts?
Yes. Sequel supports multiple connections of the same type. If you have multiple PostHog accounts or properties, add each as a separate connection in Sequel. ChatGPT will be able to query all of them.
How do I connect Sequel to ChatGPT?
In ChatGPT, go to Settings → Beta Features → Connectors (or Settings → Integrations, depending on your plan). Enter the Sequel MCP URL and your API key as the Authorization header.
Which ChatGPT plans support MCP?
MCP connector support is available on ChatGPT Plus, Team, and Enterprise plans. Check OpenAI's latest documentation for the most current availability.
Can I use Sequel with the ChatGPT API?
Yes — you can pass Sequel as a tool in any OpenAI API request by calling Sequel's MCP endpoint and converting the tool definitions to OpenAI's tool format. Contact us for guidance on this integration.
Is my data stored by OpenAI when I query through ChatGPT?
Query results are sent to OpenAI as context within your conversation and are subject to OpenAI's data handling policies. Review OpenAI's privacy policy for details. Sequel does not store query results.
How do I connect PostHog to Sequel?
Create a Personal API Key in PostHog under Settings → Personal API Keys with read-only scopes: query:read, event_definitions:read, property_definitions:read, insight:read, cohort:read, project:read. Paste it into Sequel along with your host (US Cloud, EU Cloud, or self-hosted base URL) and your numeric project ID, then click Test.
Does Sequel work with PostHog Cloud and self-hosted PostHog?
Both. For PostHog Cloud, use https://us.posthog.com or https://eu.posthog.com. For self-hosted, point the host field at your own base URL (no trailing slash) — as long as the same Personal API Key endpoints exist, Sequel works identically.
What is HogQL, and why does it matter?
HogQL is PostHog's SQL dialect that runs against the raw events table. It's strictly more expressive than the insight builder — joins, window functions, conditional aggregations. Sequel writes HogQL under the hood, which is why it can answer questions a built-in insight can't.
Can Sequel write or change anything in PostHog?
No. The connector only ships read-only tools (HogQL query, list events, list properties, list insights, list cohorts) and works with read-only scopes. The agent cannot create insights, dashboards, cohorts, or feature flags.
