Copilot Chat and Copilot Agent both honor MCP servers declared in your VS Code settings. Hail joins as a tool group available to any agent task.
Add the Hail MCP server using the snippet below. Paste it where this client expects MCP servers — the path varies, the shape doesn't.
Command Palette → MCP: Add Server (or edit .vscode/mcp.json)JSON · .vscode/mcp.json
{
"servers": {
"hail": {
"type": "http",
"url": "https://mcp.hail.so"
}
}
}Reload the client. On first use it pops a browser tab — sign in to Hail (or sign up — takes 30 seconds), click Allow, and tokens flow back to the client. Send the prompt below — if a call is placed, an SMS lands, or an email shows up in the inbox view, you're done.
Self-host on your own carrier or claim a managed number. Either way, your agent picks up the phone in ~120 seconds.
