 ### Do I need to install the Copilot CLI separately?
 
-Yes, the Copilot CLI must be installed separately. The SDKs communicate with the Copilot CLI in server mode to provide agent capabilities.
+No — for Node.js, Python, and .NET SDKs, the Copilot CLI is bundled automatically as a dependency. You do not need to install it separately.

+For Go SDK, you may still need to install the CLI manually.

+Advanced: You can override the bundled CLI using `cliPath` or `cliUrl` if you want to use a custom CLI binary or connect to an external server.

+## Tool Configuration
+
+You can control which tools are available to an MCP server using the `tools` field.
+
+### Allow all tools
+
+Use `"*"` to enable all tools provided by the MCP server:
+
+```typescript
+tools: ["*"]
+```
+
+---
+
+### Allow specific tools
+
+Provide a list of tool names to restrict access:
+
+```typescript
+tools: ["bash", "edit"]
+```
+
+Only the listed tools will be available to the agent.

+### Disable all tools
+
+Use an empty array to disable all tools:

+tools: []

+### Notes

+- The `tools` field defines which tools are allowed.
+- There is no separate `allow` or `disallow` configuration — tool access is controlled directly through this list.

 # Local CLI Setup
 
-Use the Copilot SDK with the CLI already signed in on your machine. This is the simplest configuration — zero auth code, zero infrastructure.
+Use the Copilot SDK with a Copilot CLI instance signed in on your machine. Depending on the SDK, this may be a bundled CLI (included automatically) or a system-installed CLI available in your PATH. This is the simplest configuration — zero auth code, zero infrastructure.
 
 **Best for:** Personal projects, prototyping, local development, learning the SDK.
 
 ## How It Works
 
-When you install the Copilot CLI and sign in, your credentials are stored in the system keychain. The SDK automatically starts the CLI as a child process and uses those stored credentials.
