+# Model Context Protocol Examples
+
+This directory contains examples demonstrating how to use the Model Context Protocol (MCP) Rust SDK.
+
+## Structure
+
+- `clients/`: Examples of MCP clients
+- `servers/`: Examples of MCP servers
+- `macros/`: Examples of MCP macros
+
+## Running Client Examples
+
+The client examples demonstrate different ways to connect to MCP servers.
+
+### Available Examples
+
+You can run the examples in two ways:
+
+#### Option 1: From the examples/clients directory
+
+```bash
+cd examples/clients
+cargo run --example clients
+cargo run --example sse
+cargo run --example stdio
+cargo run --example stdio_integration
+```
+
+#### Option 2: From the root directory
+
+```bash
+cargo run -p mcp-client-examples --example clients
+cargo run -p mcp-client-examples --example sse
+cargo run -p mcp-client-examples --example stdio
+cargo run -p mcp-client-examples --example stdio_integration
+```
+
+## Running Server Examples
+
+The server examples demonstrate how to implement MCP servers.
+
+### Available Examples
+
+You can run the server examples in two ways:
+
+#### Option 1: From the examples/servers directory
+
+```bash
+cd examples/servers
+cargo run --example counter-server
+```
+
+#### Option 2: From the root directory
+
+```bash
+cargo run -p mcp-server-examples --example counter-server
+```
+
+## Running Macros Examples
+
+The macros examples demonstrate how to use the MCP macros to create tools.
+
+### Available Examples
+
+You can run the macros examples in two ways:
+
+#### Option 1: From the examples/macros directory
+
+```bash
+cd examples/macros
+cargo run --example calculator
+```
+
+#### Option 2: From the root directory
+
+```bash
+cargo run -p mcp-macros-examples --example calculator
+```
+
+## Notes
+
+- Some examples may require additional setup or running both client and server components.
+- The server examples use standard I/O for communication, so they can be connected to client examples using stdio transport.
+- For SSE examples, you may need to run a separate SSE server or use a compatible MCP server implementation.
