VAST MCP Server

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.

Overview

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.

Architecture

• TypeScript for type-safe implementation

• @modelcontextprotocol/sdk for MCP protocol handling

• Axios for HTTP/REST API communication

• Winston for logging (to stderr to avoid protocol corruption)

• OpenAPI 3.0 specification for automatic tool generation

Installation

Step 1: Build

npm install
npm run build

Step 2: Configure Environment

Option A: Interactive Setup (Recommended)

node setup.js

Option B: Manual Setup

cp .env.example .env
# Edit .env with your VAST cluster details

Required environment variables:

VAST_API_BASE_URL=https://your-vast-cluster.example.com
VAST_API_USERNAME=your-username
VAST_API_PASSWORD=your-password
VAST_SSL_VERIFY=false
LOG_LEVEL=info

Step 3: Configure LLM Client

For VSCode with GitHub Copilot

1. Open VSCode Settings: Cmd+Shift+P → "Preferences: Open User Settings (JSON)"

2. Add this configuration to your settings.json:

{
  "github.copilot.chat.mcp.servers": {
    "vast": {
      "command": "node",
      "args": ["/path/to/vast_MCP/dist/main.js"],
      "env": {
        "VAST_API_BASE_URL": "https://your-vast-cluster.example.com",
        "VAST_API_USERNAME": "your-username",
        "VAST_API_PASSWORD": "your-password",
        "LOG_LEVEL": "info"
      }
    }
  }
}

3. Reload VS Code: Cmd+Shift+P → "Developer: Reload Window"

For Claude Desktop

1. Locate your Claude Desktop configuration file:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

   • Windows: %APPDATA%\Claude\claude_desktop_config.json

   • Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this configuration to claude_desktop_config.json:

{
  "mcpServers": {
    "vast": {
      "command": "node",
      "args": ["/path/to/vast_MCP/dist/main.js"],
      "env": {
        "VAST_API_BASE_URL": "https://your-vast-cluster.example.com",
        "VAST_API_USERNAME": "your-username",
        "VAST_API_PASSWORD": "your-password",
        "LOG_LEVEL": "info"
      }
    }
  }
}

3. Restart Claude Desktop application
