  permanent hosting on arweave  ◆  sitestone.io

mcp-sitestone

MCP server for deploying websites to Arweave permanent storage via Site Stone.

Works with Claude Code and any MCP-compatible client.

Quick Start

1. Add to Claude Code

Add this to your ~/.claude/settings.json:

{
  "mcpServers": {
    "sitestone": {
      "command": "npx",
      "args": ["-y", "mcp-sitestone"],
      "env": {
        "SITESTONE_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

2. Get an API Key

If you have the /sitestone slash command installed, just run /sitestone — it walks you through account creation and key setup automatically.

Otherwise, get a key at sitestone.io.

3. Deploy

Ask Claude to deploy your site:

"Deploy my dist/ folder to Arweave"

Your site gets a permanent URL that can never go down or be taken offline.

Tools

| Tool | Description | |------|-------------| | deploy_site | Upload files to Arweave. Pass file paths and an optional site name. | | list_sites | List all your deployed sites. | | get_site | Get details about a specific site (versions, domain, TX IDs). |

Limits

• Max 500 files per deploy
• Max 10 MB per file
• Max 50 MB total per deploy

What is Site Stone?

Site Stone is a deployment tool for the Arweave blockchain. Your website files are stored permanently and publicly on Arweave — no hosting fees, no expiration, no downtime. We are not the host; Arweave is.
