+## Docker Image
+
+You can run the server as a Docker container. The process communicates over stdio, so it will wait for an MCP client connection. Pass your ZenML credentials via environment variables.
+
+### Prebuilt Images (Docker Hub)
+
+Pull the latest multi-arch image:
+
+```bash
+docker pull zenmldocker/mcp-zenml:latest
+```
+
+Versioned releases are tagged as `vX.Y.Z`:
+
+```bash
+docker pull zenmldocker/mcp-zenml:v1.0.0
+```
+
+Run with your ZenML credentials (stdio mode):
+
+```bash
+docker run -i --rm \
+  -e ZENML_STORE_URL="https://your-zenml-server.example.com" \
+  -e ZENML_STORE_API_KEY="your-api-key" \
+  zenmldocker/mcp-zenml:latest
+```
+
+### Build Locally
+
+From the repository root:
+
+```bash
+docker build -t zenmldocker/mcp-zenml:local .
+```
+
+Run the locally built image:
+
+```bash
+docker run -i --rm \
+  -e ZENML_STORE_URL="https://your-zenml-server.example.com" \
+  -e ZENML_STORE_API_KEY="your-api-key" \

 ## Desktop Extensions (DXT) Support
 
 This project supports [Anthropic's Desktop Extensions (DXT) standard](https://www.anthropic.com/engineering/desktop-extensions), which makes installing MCP servers as simple as clicking a button. DXT is a new packaging format that bundles entire MCP servers into a single `.dxt` file, including all dependencies and providing user-friendly configuration.
