What is the Vast MCP MCP server?

Connect Vast MCP to Claude, Cursor or any other MCP client and it stops being a tab you switch to. MCP server for VAST Data API - enables LLMs to interact with VAST storage infrastructure. The vast mcp mcp server is what makes that connection.

What the server does

An MCP (Model Context Protocol) server that enables LLMs to interact with VAST Data storage APIs. This server exposes VAST Data management endpoints as tools for comprehensive storage infrastructure management and automation.

This project implements a Model Context Protocol (MCP) server for the VAST Data storage API, allowing LLMs like GitHub Copilot and Claude to interact with VAST storage infrastructure through natural language commands.

Installation

npm on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • viewsGetAll — List all file system views
  • viewsGetById — Get specific view details
  • viewsCreate — Create new file system views (NFS, SMB, S3)
  • viewsUpdate — Update view configuration
  • viewsDelete — Delete a view
  • quotasGetAll — List all quotas
  • quotasGetById — Get specific quota details
  • quotasCreate — Create new quotas with hard/soft limits
  • quotasUpdate — Update quota configuration
  • quotasDelete — Delete a quota
  • vippoolsGetAll — List all VIP pools
  • vippoolsGetById — Get specific VIP pool details

Credentials and setup notes

Configuration is passed through the environment: VAST_API_BASE_URL, VAST_API_USERNAME, VAST_API_PASSWORD, LOG_LEVEL, OPENAPI_SPEC_PATH. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

  • Node.js 18+ installed - VSCode with GitHub Copilot or Claude Desktop - VAST Data cluster with API access - VAST API credentials (username and password)

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Vast MCP.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

Among the file and storage access options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Vast MCP's toolset — viewsGetAll, viewsGetById, viewsCreate and 11 more — is a fair guide to whether it matches your workflow. It is maintained by jim-coyne; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Frequently asked questions

It connects Vast MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (viewsGetAll, viewsGetById, viewsCreate, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Vast MCP directly.
