+# MCP Simple Resource
+
+A simple MCP server that exposes sample text files as resources.
+
+## Usage
+
+Start the server using either stdio (default) or Streamable HTTP transport:
+
+```bash
+# Using stdio transport (default)
+uv run mcp-simple-resource
+
+# Using Streamable HTTP transport on custom port
+uv run mcp-simple-resource --transport streamable-http --port 8000
+```
+
+The server exposes some basic text file resources that can be read by clients.
+
+## Example
+
+Using the MCP client, you can retrieve resources like this using the STDIO transport:
+
+```python
+import asyncio
+from pydantic import AnyUrl
+from mcp.client.session import ClientSession
+from mcp.client.stdio import StdioServerParameters, stdio_client
+
+
+async def main():
+    async with stdio_client(
+        StdioServerParameters(command="uv", args=["run", "mcp-simple-resource"])
+    ) as (read, write):
+        async with ClientSession(read, write) as session:
+            await session.initialize()
+
+            # List available resources
+            resources = await session.list_resources()
+            print(resources)
+
+            # Get a specific resource
+            resource = await session.read_resource(AnyUrl("file:///greeting.txt"))
+            print(resource)
+
+
+asyncio.run(main())
+
+```
