How to Connect Mixpanel to Windsurf

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

Short answer

Connect Mixpanel to Sequel, then add Sequel's MCP server to Windsurf using the config on this page. Windsurf can then query your live Mixpanel data in plain English, with no connector code and no CSV exports. Both steps take a few minutes.

Example prompts

Everything you can ask Windsurf about your Mixpanel data.

Ask in plain English — Sequel translates it into a Mixpanel query, runs it, and Windsurf hands back the answer. No SQL, no dashboards, no CSV exports.

What you can ask Windsurf
  • How many users completed 'Subscription Started' last week, by plan?
  • Show me the signup → activation funnel conversion for the past 30 days.
  • Compare DAU for iOS vs Android over the last 60 days.
  • What's the average value of 'Order Placed' broken down by country?
  • Which step in funnel 4321 has the biggest drop-off?

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 Sequel to the agent

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

3

Ask Windsurf about your data

Restart Windsurf and start asking questions. "How many users completed 'Subscription Started' last week, by plan?" — and get a real answer backed by live Mixpanel data.

Why Windsurf

What Windsurf does with your Mixpanel data

Cascade with real data access

Windsurf's Cascade agent can now include database queries in its multi-step workflows. Ask it to check your schema, pull production data, and use it to guide code generation — all in one flow.

Data-informed development

Stop context-switching to a SQL client when you need to understand your data. Ask Cascade to query your database directly and use the results to write more accurate code and migrations.

Python analysis alongside your code

When you need statistical analysis or visualizations, Cascade can run Python through Sequel's sandbox — pandas, matplotlib, seaborn — and show results inline in the editor.

Configuration

Add Sequel to Windsurf

Place this in ~/.codeium/windsurf/mcp_config.json and replace sql_your_api_key with a key from Settings → API Keys.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "sequel": {
      "serverUrl": "https://api.sequel.sh/mcp",
      "headers": {
        "Authorization": "Bearer sql_your_api_key"
      }
    }
  }
}

Install

Install Mixpanel MCP in Windsurf

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.

Frequently asked questions

How do I connect Mixpanel to Windsurf?

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

What Mixpanel data can Windsurf access?

Windsurf 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 Windsurf's servers?

Query results are returned to Windsurf 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. Windsurf will be able to query all of them.

Where does the Windsurf MCP config file go?

Place your MCP configuration at ~/.codeium/windsurf/mcp_config.json. Use the `serverUrl` key (not `url`) as shown in the config above — Windsurf uses a slightly different field name than other clients.

Does this work with both Cascade and Windsurf Chat?

Yes. Sequel tools are available in both Windsurf Chat (single-turn) and Cascade (multi-step agentic flows). Cascade is especially powerful because it can chain multiple Sequel tool calls together.

How do I verify Sequel is connected in Windsurf?

Open Windsurf settings and navigate to the MCP section. You should see 'sequel' listed as a connected server with a green status indicator. If it's red, check that your API key is correct and the URL is reachable.

Can my whole team use this setup?

Each team member should have their own Sequel API key (create them in Settings → API Keys). The MCP config file is personal (in the home directory), so each developer configures it independently.

How do I connect Mixpanel to Sequel?

Create a Service Account in Mixpanel under Organization Settings → Service Accounts with at least project-level read access. Copy the username (looks like `my-sa.abc123.mp-service-account`) and the secret shown once at creation, then paste both into Sequel along with your numeric project ID and region.

Why a Service Account instead of an OAuth login?

Service Accounts are the long-lived, scope-limited credential Mixpanel recommends for programmatic access. They can be revoked or rotated independently of any user's login, and they don't break when a teammate leaves. Sequel uses HTTP Basic auth with the service account username and secret.

Which Mixpanel region should I pick?

Use the region your project was created in. US projects use mixpanel.com / data.mixpanel.com. EU projects use eu.mixpanel.com / data-eu.mixpanel.com. The region toggle simply chooses which API host Sequel calls — pick the wrong one and you'll see 401s or empty results.

Can Sequel modify data in Mixpanel?

No. The connector only ships read-only tools: segmentation, funnel report, list funnels, list events, list event properties, and raw event export. The agent has no write surface, so it cannot create reports, funnels, or cohorts.
