Custom MCP

Custom MCP (Model Context Protocol) lets you expose your Coupler.io data flows via an MCP endpoint that any MCP-compatible client can connect to. Instead of sending data to a traditional database or spreadsheet, you make your data available to AI tools and applications that speak the MCP protocol — enabling custom integrations, conversational analysis, and direct consumption by any MCP client.

Why use Custom MCP as a Coupler.io destination?

• Protocol-based flexibility — Let any MCP-compatible client access your data without building custom APIs

• AI-native architecture — Designed for AI tools and applications that need structured data in machine-readable format

• Direct tool integration — Connect Zapier, n8n, Make, or any custom-made tool that supports MCP protocol

• Custom workflows — Any MCP client can consume your data for specialized business logic

Prerequisites

• An MCP-compatible client (e.g., Claude, Cursor, Zapier, n8n, Make, or a custom application)

• Basic understanding of how to configure your MCP client to connect to an external server

Quick start

Custom MCP is ideal if you're building AI-powered workflows, want to give Zapier or Make access to your data, or have any MCP client that should consume your Coupler.io data.

How to connect

1

Start a new data flow. In Coupler.io, click "Create a new data flow" and choose your data source (Google Ads, Shopify, a database — any Coupler.io source works).

2

Select Custom MCP as your destination. From the destination list, search for and select "Custom MCP."

3

Generate your token and copy connection details. Click "Generate token" and copy it along with the MCP server URL that Coupler.io provides.

4

Configure your MCP client. Fill in the JSON config of your MCP client with the token and MCP URL from the previous step. Consult with the example config provided.

5

Run the data flow. Click "Run" to send your data. Once successful, any MCP client configured with your token and URL can access the data.
