GitHub Copilot How to use Customer.io with GitHub Copilot
You want Customer.io inside GitHub Copilot so it can investigate a customer delivery issue, sync lifecycle data for a customer, trigger a targeted customer message, and honor a data-removal request — without you copy-pasting between tabs. Here is the whole setup, once.
Create your Customer.io gateway
The gateway is the thing GitHub Copilot connects to, and it is where you decide which Customer.io tools an agent may use. You create it once and every client reuses it.
-
Create an Arcade account
Sign up and open the dashboard. The free tier is enough to follow this through.
-
Create an MCP Gateway and select your Customer.io tools
In the dashboard, create a gateway and pick the Customer.io tools you want to expose. The gateway is what your client connects to, and it is where tool access is decided.
-
Copy your gateway URL
Every client below needs it.
https://api.arcade.dev/mcp/<YOUR-GATEWAY-SLUG>
Connect the gateway to GitHub Copilot
JetBrains IDEs do not support remote MCP servers with Dynamic Client Registration — configure the gateway as “Arcade Headers” in the dashboard first. Setup also differs on Visual Studio, Eclipse and Xcode; check the docs for yours.
-
In VS Code
Copilot picks up MCP servers configured in VS Code automatically, so follow the VS Code steps and you are done.
-
In JetBrains IDEs
Copilot icon → Open Chat → Agent mode → tools icon → “+ Add More Tools…”, which opens mcp.json.
-
Add the gateway with Arcade Headers
{ "servers": { "mcp-arcade": { "url": "https://api.arcade.dev/mcp/<YOUR-GATEWAY-SLUG>", "requestInit": { "headers": { "Authorization": "Bearer {arcade_api_key}", "Arcade-User-ID": "{arcade_user_id}" } } } } }

Get started with these Customer.io prompts
GitHub Copilot can now act on your Customer.io account. Click a prompt to copy it.
Use scoped credentials and tool permissions to control which Customer.io actions an agent can take. Pair it with Contextual Access policies to require approval before an agent triggers a broadcast, sends transactional email, or deletes a person record.
