+Using MCP with docker will simply the usage of rustfs mcp. Building the docker image with below command:
+
+```
+docker build -f Dockerfile -t rustfs/rustfs-mcp ../../
+```
+
+Alternatively, if you want to build the image from the rustfs codebase root directory,run the command:
+
+```
+docker build -f crates/mcp/Dockerfile -t rustfs/rustfs-mcp .
+```
+
