Release 26.04.0 · NetApp/ontap-mcp

26.04.0 / 2026-04-30 Release

The ONTAP-MCP team is happy to announce that we've released the 26.04.0 version of ONTAP-MCP. 🤘

🏅 The ONTAP-MCP server gives MCP clients like GitHub Copilot, Claude Desktop, and other large language models (LLMs) access to your NetApp ONTAP storage systems. It supports multi-cluster management and full protocol coverage across NAS, SAN block, and NVMe-oF.
🎩 Each MCP tool is annotated with behavior hints (create/read/update/delete annotations) so clients can reason about safety.
💎 This version also includes a Swagger-driven catalog that lets AI clients explore any ONTAP GET REST endpoint we haven't already wrapped.
Join Discord and GitHub discussions to participate in the conversation, ask questions, and share your feedback.
📕 Documentation is available at https://netapp.github.io/ontap-mcp/26.04/ and full list of tools is available at https://netapp.github.io/ontap-mcp/26.04/tools/.
