Shelby

MCP server for Shelby Protocol — connect AI agents to decentralized storage.

Works with Claude Desktop, Cursor, Claude Code, Codex, and any MCP-compatible client.

What it does

AI agents can read, write, and manage files on Shelby's decentralized storage network (Aptos) through 5 tools:

Tool	Description
shelby_upload	Upload text content to Shelby storage
shelby_download	Download a blob and return its content
shelby_list	List blobs under current account
shelby_delete	Delete a blob
shelby_account	Show account info, balance, network

Prerequisites

• Node.js v18+
• Shelby CLI installed and configured (npm install -g @shelby-protocol/cli)
• A funded Shelby account (shelby faucet)

Install

git clone https://github.com/Jasekeee/shelby-mcp.git
cd shelby-mcp
npm install
npm run build

Use with Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "shelby": {
      "command": "node",
      "args": ["/absolute/path/to/shelby-mcp/build/index.js"]
    }
  }
}

Restart Claude Desktop. You can now say:

"Upload this report to Shelby as reports/q1-2026.txt"

"Download my config from Shelby"

"What's my Shelby account balance?"

Use with Cursor

Add to .cursor/mcp.json in your project:

{
  "mcpServers": {
    "shelby": {
      "command": "node",
      "args": ["/absolute/path/to/shelby-mcp/build/index.js"]
    }
  }
}

Use with Claude Code

claude mcp add shelby node /absolute/path/to/shelby-mcp/build/index.js

Architecture

AI Agent (Claude/Cursor/Codex)
    ↕ MCP Protocol (stdio)
shelby-mcp server
    ↕ CLI wrapper
shelby CLI → Aptos blockchain → Shelby storage network

The server wraps the shelby CLI rather than using the SDK directly. This ensures compatibility across CLI versions and avoids SDK breaking changes.

Configuration

shelby-mcp reads from your existing ~/.shelby/config.yaml. No additional configuration needed — if shelby upload works in your terminal, it works through MCP.
