-Beyond `/mcp show`, there are several other commands for managing your MCP servers:
+You can manage MCP servers in two ways: using **slash commands inside a chat session**, or using the **`copilot mcp` command directly in your terminal** (no chat session needed).
+
+### Option 1: Slash commands (inside a chat session)
+
+These work when you're already inside `copilot`:
 
 | Command | What It Does |
 |---------|--------------|
 | `/mcp show` | Show all configured MCP servers and their status |
 | `/mcp add` | Interactive setup for adding a new server |
 | `/mcp edit <server-name>` | Edit an existing server configuration |
-| `/mcp enable <server-name>` | Enable a disabled server |
-| `/mcp disable <server-name>` | Temporarily disable a server |
+| `/mcp enable <server-name>` | Enable a disabled server (persists across sessions) |
+| `/mcp disable <server-name>` | Disable a server (persists across sessions) |
 | `/mcp delete <server-name>` | Remove a server permanently |
 | `/mcp auth <server-name>` | Re-authenticate with an MCP server that uses OAuth (e.g., after switching accounts) |
 
+### Option 2: `copilot mcp` command (from your terminal)
+
+You can also manage MCP servers directly from your terminal without starting a chat session first:
+
+```bash
+# List all configured MCP servers
+copilot mcp list
+
+# Enable a server
+copilot mcp enable filesystem
+
+# Disable a server
+copilot mcp disable context7
+```
+
+> 💡 **When to use which?** Use `/mcp` slash commands when you're already in a chat session. Use `copilot mcp` from the terminal when you want to quickly check or change your server settings before starting a session.
+
 For most of this course, `/mcp show` is all you need. The other commands become useful as you manage more servers over time.
