Installation

Get Kyew connected to Claude or ChatGPT in under 60 seconds.

Claude Code CLI (Recommended)

The fastest way to get started is with Claude Code CLI:

claude mcp add kyew --transport http --scope user https://mcp.kyew.ai/mcp

When prompted, click the authentication link to sign in with Google. Once authenticated, you'll have access to all 60+ Kyew tools.

Verify Connection

claude mcp list

You should see:

kyew: https://mcp.kyew.ai/mcp (HTTP) - ✓ Connected

Test It Out

ChatGPT

Kyew works with ChatGPT through the OpenAI Apps SDK.

Setup

1. Go to ChatGPT and open your app/GPT configuration
2. Add an MCP server with URL: https://mcp.kyew.ai/mcp
3. When prompted, sign in with Google

Verify

Ask ChatGPT:

What Kyew tools are available?

You should see 60+ tools. Your data syncs across both Claude and ChatGPT when using the same Google account.

Claude Desktop

For Claude Desktop, add the following to your MCP configuration file:

macOS

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "kyew": {
      "command": "npx",
      "args": ["-y", "@anthropic-ai/mcp-remote-http", "https://mcp.kyew.ai/mcp"]
    }
  }
}

Windows

Edit %APPDATA%\Claude\claude_desktop_config.json:

{
  "mcpServers": {
    "kyew": {
      "command": "npx",
      "args": ["-y", "@anthropic-ai/mcp-remote-http", "https://mcp.kyew.ai/mcp"]
    }
  }
}

After saving, restart Claude Desktop. You'll be prompted to authenticate with Google on first use.

Authentication

Kyew uses Google OAuth for authentication. When you first connect:

1. A browser window opens with the Google sign-in page
2. Sign in with your Google account
3. Grant access to Kyew
4. You're redirected back to your client with access granted

User-Scoped Data

All your data is private to your Google account:

Your Google Account → userId: google:1234567890
  ├─ Memories: Private, encrypted
  ├─ Skills: Private, encrypted
  ├─ Tools: Private, encrypted
  └─ Connections: Private, encrypted

Other users cannot access your data. Each Google account gets completely isolated storage.

Cross-Device and Cross-Client Sync

Same Google account = same data everywhere:

Claude Desktop:  Sign in with you@gmail.com → All data available
Claude Code:     Sign in with you@gmail.com → Same data synced
ChatGPT:         Sign in with you@gmail.com → Same data synced

• Google Account: Required for authentication
• MCP Client: Any MCP-compatible client:
  • Claude Code CLI v1.0.0+
  • Claude Desktop (latest)

Troubleshooting
