MCP Integration

Connect Mixpanel to Codex

Query your Mixpanel data directly from Codex using Sequel’s MCP server. Ask questions in plain English — no SQL, no dashboards, no context switching.

How it works

Three steps to get started

1

Connect Mixpanel to Sequel

In your Sequel dashboard, go to Connections and add Mixpanel. Sequel handles authentication and schema discovery automatically.

2

Add the MCP config

Copy the Sequel MCP configuration into Codex's settings file (shown below). Swap in your API key from Settings → API Keys.

3

Ask Codex about your data

Restart Codex and start asking questions. "undefined" — and get a real answer backed by live Mixpanel data.

Configuration

Add Sequel to Codex

Place this in ~/.codex/config.yaml and replace sql_your_api_key with a key from Settings → API Keys.

~/.codex/config.yaml

mcp_servers:
  sequel:
    type: http
    url: https://api.sequel.sh/mcp
    headers:
      Authorization: "Bearer sql_your_api_key"

Frequently asked questions

How do I connect Mixpanel to Codex?

You need two things: (1) connect Mixpanel to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to Codex using the setup shown above. Once both are done, Codex can query your Mixpanel data directly.

What Mixpanel data can Codex access?

Codex can access any data available through your Mixpanel 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 Mixpanel data sent to Codex's servers?

Query results are returned to Codex 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 Mixpanel and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to Mixpanel and generate an API key from Settings → API Keys.

Can I connect multiple Mixpanel accounts?

Yes. Sequel supports multiple connections of the same type. If you have multiple Mixpanel accounts or properties, add each as a separate connection in Sequel. Codex will be able to query all of them.
