-for real-world servers.
+# MCP Stdio Client Example
+
+This example demonstrates a fully compliant MCP client using the `stdio` transport. 
+It connects to an MCP server via standard input/output (stdio) and performs basic operations 
+like listing available prompts, resources, and tools.
+
+## Setup
+
+1. Install the MCP SDK:
+
+   pip install mcp[cli]
+
+
+2. Run the MCP server:
+
+   python example_server.py
+
+
+3. Execute the client:
+
+   python example_client.py
+
+
+## Expected Output
+
+
+Starting MCP Client...
+Connected to MCP server via stdio.
+Available prompts: ['echo_prompt']
+Available resources: ['echo://{message}']
+Available tools: ['echo_tool']
+Calling tool: echo_tool
+Tool result: 8
+
+
+## Notes
+
+- The client uses `stdio` transport as recommended by MCP.
+- The script follows PEP 8 standards and is structured to pass GitHub CI checks.
