How to Use the Customer.io MCP in Cursor

Q: Can I update a customer profile in Customer.io from inside Cursor?

Yes. The identifycustomer tool lets the agent create or update users. You can say, "Update the customer 'user@example.com' in Customer.io with the attribute 'plan' set to 'premium'."

Inject live Customer.io data and user profiles directly into your code with Cursor's AI agent.

Perplexity

Build Scripts with Real Customer Data

Stop using mock data. With this tool, you can tell Cursor's agent to fetch live data from your Customer.io account and write the code to handle it. Use `get_customer_details` to pull a real user profile and generate a struct or class that perfectly matches the data schema. This works for any data in your account. You can `list_customers` and have the agent write a script to iterate through them, or `get_campaign_performance` to build a function that analyzes the results. You're coding against actual API responses from the start.

Query Marketing Campaigns in Your Editor

Get context without switching windows. While you're working, just ask the agent, "What are our active automated campaigns?" It will use `list_automated_campaigns` and show you the list right in the chat panel. You can also check on performance. Ask for a summary of a specific campaign using `get_campaign_performance` or get a high-level overview with `get_engagement_summary`. The answers appear next to your code, where you need them.

Write Code That Manages your MCP Server

Let Cursor's agent write the boilerplate for interacting with Customer.io. For example, tell it to "write a function that takes an email and attributes to update a user." The agent will use the `identify_customer` tool's schema to generate the correct function signature and API call. This MCP Server gives your agent read-only access to your campaign lists, segments, and newsletters. You can ask it to generate code that cross-references segments (`list_customer_segments`) with campaign lists (`list_newsletters`), all without leaving your editor.

Setup guide

Set up Customer.io MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Customer.io MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Customer.io transactions." If the MCP tools are loaded correctly, Cursor will call the Customer.io tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "customerio-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }

Common questions about Customer.io MCP in Cursor

In Cursor, activate the agent and prompt it: "Get the profile for 'user@example.com' from Customer.io and list their segments." The agent uses `get_customer_details` and injects the code and data into your active file.
