Connect VS Code to Hail over MCP
MCP support in VS Code is generally available. VS Code runs the OAuth sign-in. Copilot agent mode can then use the Hail tools.
Works in Copilot Chat, Agent Mode, and VS Code CLI.
Setup
1
Add Hail to VS Code
Add the Hail MCP server with the snippet below. Open the Command Palette, run MCP: Add Server, then select HTTP.
.vscode/mcp.json
{
"servers": {
"hail": {
"type": "http",
"url": "https://mcp.hail.so"
}
}
}2
Approve access and send a test prompt
Reload the client. On first use, the client opens a browser tab. Sign in to Hail or create an account. Click Allow. Then send the prompt below. The setup works if Hail places the call or sends the message.
Copilot Chat (agent mode): "Use hail to email the on-call about the incident."Notes
