+
+#### 🚫 Not Distributed
+
+An image for AMD ROCm 6.3 (`docling-serve-rocm`) is supported but **not published** due to its large size.
+
+To build it locally:
+
+```bash
+git clone --branch main git@github.com:docling-project/docling-serve.git
+cd docling-serve/
+make docling-serve-rocm-image
+```
+
+For deployment using Docker Compose, see [docs/deployment.md](docs/deployment.md).
 
 Coming soon: `docling-serve-slim` images will reduce the size by skipping the model weights download.

+#### Gradio UI
+
+When using Gradio UI and using the option to output conversion as file, Gradio uses cache to prevent files to be overwritten ([more info here](https://www.gradio.app/guides/file-access#the-gradio-cache)), and we defined the cache clean frequency of one hour to clean files older than 10hours. For situations that files need to be available to download from UI older than 10 hours, there is two options:
+
+- Increase the older age of files to clean [here](https://github.com/docling-project/docling-serve/blob/main/docling_serve/gradio_ui.py#L483) to suffice the age desired;
+- Or set the clean up manually by defining the temporary dir of Gradio to use the same as `DOCLING_SERVE_SCRATCH_PATH` absolute path. This can be achieved by setting the environment variable `GRADIO_TEMP_DIR`, that can be done via command line `export GRADIO_TEMP_DIR="<same_path_as_scratch>"` or in `Dockerfile` using `ENV GRADIO_TEMP_DIR="<same_path_as_scratch>"`. After this, set the clean of cache to `None` [here](https://github.com/docling-project/docling-serve/blob/main/docling_serve/gradio_ui.py#L483). Now, the clean up of `DOCLING_SERVE_SCRATCH_PATH` will also clean the Gradio temporary dir. (If you use this option, please remember when reversing changes to remove the environment variable `GRADIO_TEMP_DIR`, otherwise may lead to files not be available to download).

+## Split processing
+
+The example of provided of split processing demonstrates how to split a PDF into chunks of pages and send them for conversion. At the end, it concatenates all split pages into a single conversion `JSON`.
+
+At beginning of file there's variables to be used (and modified) such as:
+| Variable | Description |
+| ---------|-------------|
+| `path_to_pdf`| Path to PDF file to be split |
+| `pages_per_file`| The number of pages per chunk to split PDF |
+| `base_url`| Base url of the `docling-serve` host |
+| `out_dir`| The output folder of each conversion `JSON` of split PDF and the final concatenated `JSON` |
+
+The example follows the following logic:
+- Get the number of pages of the `PDF`
+- Based on the number of chunks of pages, send each chunk to conversion using `page_range` parameter
+- Wait all conversions to finish
+- Get all conversion results
+- Save each conversion `JSON` result into a `JSON` file
+- Concatenate all `JSONs` into a single `JSON` using `docling` concatenate method
+- Save concatenated `JSON` into a `JSON` file

+# Docling MCP in Docling Serve
+
+The `docling-serve` container image includes all MCP (Model Communication Protocol) features starting from version v1.1.0. To leverage these features, you simply need to use a different entrypoint—no custom image builds or additional installations are required. The image provides the `docling-mcp-server` executable, which enables MCP functionality out of the box as of version v1.1.0 ([changelog](https://github.com/docling-project/docling-serve/blob/624f65d41b734e8b39ff267bc8bf6e766c376d6d/CHANGELOG.md)).
+
+Read more on [Docling MCP](https://github.com/docling-project/docling-mcp) in its dedicated repository.
+
+## Launching the MCP Service
+
+By default, the container runs `docling-serve run` and exposes port 5001. To start the MCP service, override the entrypoint and specify your desired port mapping. For example:
+
+```sh
+podman run -p 8000:8000 quay.io/docling-project/docling-serve -- docling-mcp-server --transport streamable-http --port 8000 --host 0.0.0.0
+```
+
+This command starts the MCP server on port 8000, accessible at `http://localhost:8000/mcp`. Adjust the port and host as needed. Key arguments for `docling-mcp-server` include `--transport streamable-http` (HTTP transport for client connections), `--port <PORT>`, and `--host <HOST>` (use `0.0.0.0` to accept connections from any interface).
+
+## Configuring MCP Clients
+
+Most MCP-compatible clients, such as LM Studio and Claude Desktop, allow you to specify custom MCP server endpoints. The standard configuration uses a JSON block to define available MCP servers. For example, to connect to the Docling MCP server running on port 8000:
+
+```json
+{
+  "mcpServers": {
+    "docling": {
+      "url": "http://localhost:8000/mcp"
+    }
+  }
+}
+```
+
+Insert this configuration in your client's settings where MCP servers are defined. Update the URL if you use a different port.
+
+### LM Studio and Claude Desktop
+
+Both LM Studio and Claude Desktop support MCP endpoints via configuration files or UI settings. Paste the above JSON block into the appropriate configuration section. For Claude Desktop, add the MCP server in the "Custom Model" or "MCP Server" section. For LM Studio, refer to its documentation for the location of the MCP server configuration.
+
+### Other MCP Clients
+
+Other clients, such as Continue Coding Assistant, also support custom MCP endpoints. Use the same configuration pattern: provide the MCP server URL ending with `/mcp` and ensure the port matches your container setup. See the [Docling MCP docs](https://github.com/docling-project/docling-mcp/tree/main/docs/integrations) for more details.

+# Handling Models in Docling Serve
+
+When enabling steps in Docling Serve that require extra models (such as picture classification, picture description, table detection, code recognition, formula extraction, or vision-language modules), you must ensure those models are available in the runtime environment. The standard container image includes only the default models. Any additional models must be downloaded and made available before use. If required models are missing, Docling Serve will raise runtime errors rather than downloading them automatically. This default choice wants to guarantee the system is not calling external services.
+
+## Model Storage Location
+
+Docling Serve loads models from the directory specified by the `DOCLING_SERVE_ARTIFACTS_PATH` environment variable. This path must be consistent across model download and runtime. When running with multiple workers or reload enabled, you must use the environment variable rather than the CLI argument for configuration [[source]](./configuration.md).
+
+## Approaches for Making Extra Models Available
+
+There are several ways to ensure required models are present:
+
+### 1. Disable Local Models (Trigger Auto-Download)
+
+You can configure the container to download all models at startup by clearing the artifacts path:
+
+```sh
+podman run -d -p 5001:5001 --name docling-serve \
+  -e DOCLING_SERVE_ARTIFACTS_PATH="" \
+  -e DOCLING_SERVE_ENABLE_UI=true \
+  quay.io/docling-project/docling-serve
+```
+
+This approach is simple for local development but not recommended for production, as it increases startup time and depends on network availability.
+
+### 2. Build a Custom Image with Pre-Downloaded Models
+
+You can create a new image that includes the required models:
+
+```Dockerfile
+FROM quay.io/docling-project/docling-serve
+RUN docling-tools models download smolvlm
+```
+
+This method is suitable for production, as it ensures all models are present in the image and avoids runtime downloads.
+
+### 3. Update the Entrypoint to Download Models Before Startup
+
+You can override the entrypoint to download models before starting the service:
+
+```sh
+podman run -p 5001:5001 -e DOCLING_SERVE_ENABLE_UI=true \
+  quay.io/docling-project/docling-serve \
+  -- sh -c 'exec docling-tools models download smolvlm && exec docling-serve run'
+```
+
+This is useful for environments where you want to keep the base image unchanged but still automate model preparation.
+
+### 4. Mount a Volume with Pre-Downloaded Models
+
+Download models locally and mount them into the container:
+
+```sh
+# Download the models locally
+docling-tools models download --all -o models
+
+# Start the container with the local models folder

+
+This approach is robust for both local and production deployments, especially when using persistent storage.
+
+## Kubernetes/Cluster Deployments
+
+For Kubernetes or OpenShift clusters, the recommended approach is to use a PersistentVolumeClaim (PVC) for model storage, a Kubernetes Job to download models, and mount the volume into the deployment. This ensures models persist across pod restarts and scale-out scenarios.
+
+### Example: PersistentVolumeClaim
+
+```yaml
+apiVersion: v1
+kind: PersistentVolumeClaim
+metadata:
+  name: docling-model-cache-pvc
+spec:
+  accessModes:
+    - ReadWriteOnce
+  volumeMode: Filesystem
+  resources:
+    requests:
+      storage: 10Gi
+```
+
+If you don't want to use default storage class, set your custom storage class with following:
+
+```yaml
+spec:
+    ...
+    storageClassName: <Storage Class Name>
+```
+
+Manifest example: [docling-model-cache-pvc.yaml](./deploy-examples/docling-model-cache-pvc.yaml)
+
+### Example: Model Download Job
+
+```yaml
+apiVersion: batch/v1
+kind: Job
+metadata:
+  name: docling-model-cache-load
+spec:
+  template:
+    spec:
+      containers:
+        - name: loader
+          image: ghcr.io/docling-project/docling-serve-cpu:main
+          command:
+            - docling-tools
+            - models
+            - download
+            - '--output-dir=/modelcache'
+            - 'layout'
+            - 'tableformer'
+            - 'code_formula'
+            - 'picture_classifier'
+            - 'smolvlm'
+            - 'granite_vision'
+            - 'easyocr'
+          volumeMounts:
+            - name: docling-model-cache
+              mountPath: /modelcache
+      volumes:
+        - name: docling-model-cache
+          persistentVolumeClaim:
+            claimName: docling-model-cache-pvc
+      restartPolicy: Never
+```
+
+The job will mount the previously created persistent volume and execute command similar to how we would load models locally:
+`docling-tools models download --output-dir <MOUNT-PATH> [LIST_OF_MODELS]`
+
+In manifest, we specify desired models individually, or we can use `--all` parameter to download all models.
+
+Manifest example: [docling-model-cache-job.yaml](./deploy-examples/docling-model-cache-job.yaml)
+
+### Example: Deployment with Mounted Volume
+
+```yaml
+spec:
+  template:
+    spec:
+      containers:
+        - name: api
+          env:
+            - name: DOCLING_SERVE_ARTIFACTS_PATH
+              value: '/modelcache'
+          volumeMounts:
+            - name: docling-model-cache
+              mountPath: /modelcache
+      volumes:
+        - name: docling-model-cache
+          persistentVolumeClaim:
+            claimName: docling-model-cache-pvc
+```
+
+The value of `DOCLING_SERVE_ARTIFACTS_PATH` must match the mount path where models are stored.
+
+Now, when docling-serve is executing tasks, the underlying docling installation will load model weights from mounted volume.
+
+Manifest example: [docling-model-cache-deployment.yaml](./deploy-examples/docling-model-cache-deployment.yaml)
+
+## Local Docker Execution
+
+For local Docker or Podman execution, you can use any of the approaches above. Mounting a local directory with pre-downloaded models is the most reliable for repeated runs and avoids network dependencies.
+
+## Troubleshooting and Best Practices
+
+- If a required model is missing from the artifacts path, Docling Serve will raise a runtime error.
+- Always ensure the value of `DOCLING_SERVE_ARTIFACTS_PATH` matches the directory where models are stored and mounted.
+- For production and cluster environments, prefer persistent storage and pre-loading models via a dedicated job.

-# Pre-loading models for docling
-
-This document provides examples for pre-loading docling models to a persistent volume and re-using it for docling-serve deployments.
-
-1. We need to create a persistent volume that will store models weights:
-
-    ```yaml
-    apiVersion: v1
-    kind: PersistentVolumeClaim
-    metadata:
-      name: docling-model-cache-pvc
-    spec:
-      accessModes:
-        - ReadWriteOnce
-      volumeMode: Filesystem
-      resources:
-        requests:
-          storage: 10Gi
-    ```
-
-    If you don't want to use default storage class, set your custom storage class with following:
-
-    ```yaml
-    spec:
-      ...
-      storageClassName: <Storage Class Name>
-    ```
-
-    Manifest example: [docling-model-cache-pvc.yaml](./deploy-examples/docling-model-cache-pvc.yaml)
-
-2. In order to load model weights, we can use docling-toolkit to download them, as this is a one time operation we can use kubernetes job for this:
-
-    ```yaml
-    apiVersion: batch/v1
-    kind: Job
-    metadata:
-      name: docling-model-cache-load
-    spec:
-      selector: {}
-      template:
-        metadata:
-          name: docling-model-load
-        spec:
-          containers:
-            - name: loader
-              image: ghcr.io/docling-project/docling-serve-cpu:main
-              command:
-                - docling-tools
-                - models
-                - download
-                - '--output-dir=/modelcache'
-                - 'layout'
-                - 'tableformer'
-                - 'code_formula'
-                - 'picture_classifier'
-                - 'smolvlm'
-                - 'granite_vision'
-                - 'easyocr'
-              volumeMounts:
-                - name: docling-model-cache
-                  mountPath: /modelcache
-          volumes:
-            - name: docling-model-cache
-              persistentVolumeClaim:
-                claimName: docling-model-cache-pvc
-          restartPolicy: Never
-    ```
-
-    The job will mount previously created persistent volume and execute command similar to how we would load models locally:
-    `docling-tools models download --output-dir <MOUNT-PATH> [LIST_OF_MODELS]`
-
-    In manifest, we specify desired models individually, or we can use `--all` parameter to download all models.
-
-    Manifest example: [docling-model-cache-job.yaml](./deploy-examples/docling-model-cache-job.yaml)
-
-3. Now we can mount volume in the docling-serve deployment and set env `DOCLING_SERVE_ARTIFACTS_PATH` to point to it.
-    Following additions to deployment should be made:
-
-    ```yaml
-    spec:
-      template:
-        spec:
-          containers:
-            - name: api
-              env:
-              ...
-                - name: DOCLING_SERVE_ARTIFACTS_PATH
-                  value: '/modelcache'
-              volumeMounts:
-                - name: docling-model-cache
-                  mountPath: /modelcache
-          ...
-          volumes:
-            - name: docling-model-cache
-              persistentVolumeClaim:
-                claimName: docling-model-cache-pvc
-    ```
-
-    Make sure that value of `DOCLING_SERVE_ARTIFACTS_PATH` is the same as where models were downloaded and where volume is mounted.
-
-    Now when docling-serve is executing tasks, the underlying docling installation will load model weights from mounted volume.
-
-    Manifest example: [docling-model-cache-deployment.yaml](./deploy-examples/docling-model-cache-deployment.yaml)
