How to Use the Customer.io MCP in Cursor

Q: How do I set up this MCP server in Cursor?

Add the server's configuration to your mcp.json file. You can put it in your project's .cursor directory for project-specific tools or in /.cursor for global access. After that, just use Agent mode in the chat.

Build with Real Customer Data

Stop using mock data. Tell Cursor's agent to fetch a real user profile from your production system using `get_customer_details`. You can use it to test a new function or see how your code handles actual data structures. This kills a whole class of bugs. When your code is built against the real thing from the start, you avoid surprises when you deploy. The agent can fetch a user or a list of segment members with `list_segment_members` and drop the JSON right in your editor.

Test Email Triggers from Your Editor

This MCP Server connects Cursor directly to your Customer.io transactional emails. When you're working on a feature that should trigger a message, you can have the agent send a real test email on the spot with `send_transactional_email`. You write the code, then you type a prompt: '@agent send a test welcome email to my test account.' You get instant feedback without leaving your editor, running a separate script, or clicking around in a UI. It becomes part of your core development loop.

Query Campaigns and Segments in Cursor

Get context for the code you're writing. If you're building an analytics dashboard, ask the agent to pull all active campaign names with `list_active_campaigns` so you can populate a dropdown menu. The agent doesn't just show you the list; it writes the code that uses it. Ask it to 'fetch all audience segments and create a TypeScript enum with them.' It makes the API call and generates the code in one step.

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

Common questions about Customer.io MCP in Cursor

In Cursor's chat, type '@agent get customer details for user@example.com'. The agent uses the `get_customer_details` tool and can inject the resulting JSON object directly into your open file.

Yes, that's exactly what this is for. Tell the agent, 'Fetch my Customer.io segments and write a Python dictionary from them.' It uses `list_audience_segments` and generates the code for you.

It does. You can use the agent to trigger transactional emails with the `send_transactional_email` tool. It's perfect for testing email-related features while you're still writing the code.

Add the server's configuration to your `mcp.json` file. You can put it in your project's `.cursor` directory for project-specific tools or in `~/.cursor` for global access. After that, just use Agent mode in the chat.
