+#### Example MCP Server Configurations
+
+**SSE Server Example:**
+```yaml
+mcpSSEServers:
+  filesystem:
+    url: https://yoursseserver.com
+    maxPayloadSize: 1048576 # 1MB
+```
+
+**StdIO Server Examples:**
+
+1. Using the [official filesystem MCP server](https://github.com/modelcontextprotocol/servers/tree/main/src/filesystem):
+```yaml
+mcpStdIOServers:
+  filesystem:
+    command: npx
+    args:
+      - -y
+      - "@modelcontextprotocol/server-filesystem"
+      - "/path/to/your/files"
+```
+This example can be used directly as the official filesystem mcp server is an executable package that can be run with npx. Just update the path to point to your desired directory.
+
+2. Using [go-mcp filesystem MCP server](https://github.com/MegaGrindStone/go-mcp/tree/main/servers/filesystem):
+```yaml
+mcpStdIOServers:
+  filesystem:
+    command: go
+    args:
+      - run
+      - github.com/your_username/your_app # Replace with your app
+      - -path
+      - "/data/mcp/filesystem" # Path to expose to MCP clients
+```
+For this example, you'll need to create a new Go application that imports the `github.com/MegaGrindStone/go-mcp/servers/filesystem` package. The flag naming (like `-path` in this example) is completely customizable based on how you structure your own application - it doesn't have to be called "path". [This example](https://github.com/MegaGrindStone/go-mcp/blob/main/example/filesystem/main.go) is merely a starting point showing one possible implementation where a flag is used to specify which directory to expose. You're free to design your own application structure and command-line interface according to your specific needs.
