Provides tools for querying and managing NetApp ONTAP storage clusters, including cluster configuration, provisioning, and deletion capabilities (provisioning/deletion disabled by default in read-only mode).
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@ONTAP-MCP show me the volumes on the ONTAP cluster and their used space"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Installs NetApp's official open-source ONTAP-MCP server as a Claude Desktop extension, so Claude can query and manage your ONTAP storage clusters directly.
ONTAP-MCP ships only as a Docker container speaking Streamable HTTP — it has no stdio mode. Claude Desktop's custom connector feature requires a server reachable from the public internet, which a server sitting in front of your storage cluster usually isn't and shouldn't be. Desktop Extensions solve both problems: this extension runs entirely on your own machine and talks to Claude Desktop over stdio, exactly like any other local extension.
Under the hood, server/index.js:
Writes an ontap.yaml config file (from your settings below) to
~/.ontap-mcp-desktop-extension/.
Starts the ghcr.io/netapp/ontap-mcp Docker container, published only to 127.0.0.1
on your machine — never exposed to your network or the internet.
Waits for it to report healthy, then bridges Claude Desktop's stdio connection to that local
HTTP server using mcp-remote (bundled — no
internet access needed at runtime for this part).

Network connectivity from your machine to your ONTAP cluster's management LIF.

Setting | Notes |
ONTAP Cluster Address | Hostname or IP of the cluster's management LIF |
ONTAP Username / Password | Password is stored by Claude Desktop and written only to a local file, mounted read-only into the container |
Skip TLS Certificate Verification | On by default — most on-prem clusters use self-signed certs |
Read-Only Mode | On by default. No provisioning/deletion tools are registered until you turn this off |
Docker Image | Defaults to |
Local Port | Host port the container is published on (127.0.0.1 only); change if 8083 is taken |
Additional Clusters (advanced) | Raw YAML to add more |
ONTAP-MCP has no built-in authentication of its own unless you separately configure OAuth
(not covered by this extension) — anything that can reach the assistant using this extension
can use these tools. The container's port is bound to 127.0.0.1 only, so nothing on your
network can reach it directly.
Read-Only Mode is on by default specifically because of the above — turn it off only when you intend for Claude to make changes to your storage systems.
Logs (including all Docker container output) are written to:
~/.ontap-mcp-desktop-extension/container.logIf the extension fails to start, check that file first — most issues are either "Docker isn't running" or "the configured port is already in use."
