GitHub Copilot How to use E2B with GitHub Copilot
You want E2B inside GitHub Copilot so it can run reproducible data analyses, generate charts from raw data, test code in an isolated environment, and validate generated code before deployment — without you copy-pasting between tabs. Here is the whole setup, once.
Create your E2B gateway
The gateway is the thing GitHub Copilot connects to, and it is where you decide which E2B 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 E2B tools
In the dashboard, create a gateway and pick the E2B 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}" } } } } }

Try these E2B prompts
GitHub Copilot can now act on your E2B account. Click a prompt to copy it.
Treat sandbox execution as arbitrary code: use tool permissions to limit which workflows can run code or generate charts. Pair it with Contextual Access policies so an agent can run only the actions approved for its context.
