 ## Understanding MCP Clients
 
 MCP Clients are crucial components that act as the bridge between AI applications (Hosts) and external capabilities provided by MCP Servers. Think of the Host as your main application (like an AI assistant or IDE) and the Client as a specialized module within that Host responsible for handling MCP communications.

 In the next section, we'll explore the ecosystem of MCP servers available on Hugging Face Hub and how to publish your own servers there. 
 
-## Code Clients
+## Tiny Agents Clients
 
-You can also use the MCP Client within code so that the tools are available to the LLM. Let's explore some examples in `smolagents`.  To run these examples you will need to add `mcp[cli]`, `smolagents[toolkit]`, and `smolagents[mcp]` to your `uv` virtual environment.
+Now, let's explore how to use MCP Clients within code.
 
-First, let's explore our weather server from the previous page. In `smolagents`, we can use the `ToolCollection` class to automatically discover and register tools from an MCP server. This is done by passing the `StdioServerParameters` or `SSEServerParameters` to the `ToolCollection.from_mcp` method. We can then print the tools to the console.
+You can also use tiny agents as MCP Clients to connect directly to MCP servers from your code. Tiny agents provide a simple way to create AI agents that can use tools from MCP servers.
 
-```python
-from smolagents import ToolCollection
-from mcp.client.stdio import StdioServerParameters
-
-server_parameters = StdioServerParameters(command="uv", args=["run", "server.py"])
+Tiny Agent can run MCP servers with a command line environment. To do this, we will need to install `npm` and run the server with `npx`. **We'll need these for both Python and JavaScript.**
 
-with ToolCollection.from_mcp(
-    server_parameters, trust_remote_code=True
-) as tools:
-    print("\n".join(f"{tool.name}: {tool.description}" for tool in tools.tools))
+Let's install `npx` with `npm`. If you don't have `npm` installed, check out the [npm documentation](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm).
 
+```bash
+# install npx
+npm install -g npx

-We can also connect to an MCP server that is hosted on a remote machine. In this case, we need to pass the `SSEServerParameters` to the `MCPClient` class.

-Now, let's see how we can use the MCP Client in a code agent. 
+Now you can run the agent:
 
-```python
