Enterprise-managed MCP allowlists shipped August 6 across the Copilot app, Copilot CLI and VS Code, configured with allowedMcpServers and deniedMcpServers in copilot/managed-settings.json inside the org's .github-private repo. Match by serverUrl with wildcards for remote HTTP/SSE, serverCommand for local stdio, or user-assigned serverName, with overridable for team customization. Policies fail closed: a malformed or unverifiable config is blocked, not allowed. When multiple policy layers apply, a server must satisfy all of them. Fail-closed as the default is the correct call and I'm glad it wasn't a flag.
