Catio MCP Setup Guide

Connect your AI coding assistant to Catio via the Model Context Protocol (MCP). Once connected, your assistant can access your Catio workspace data directly — no copy-pasting, no context switching.

Server URL

Authentication

Catio uses OAuth 2.0 with PKCE. The first time you connect, your client opens a browser window where you:

1. Select your Catio organization
2. Select the workspace you want to work in

Your session is remembered via a refresh token — you won't need to repeat this for every conversation.

Claude Desktop

Claude Desktop is Anthropic's desktop app.

1. Add the server

Edit your claude_desktop_config.json:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "catio": {
      "type": "http",
      "url": "https://mcp.catio.tech/mcp"
    }
  }
}

2. Authenticate

Restart Claude Desktop. The first time a Catio tool is used, a browser OAuth flow opens — select your org and workspace.

3. Verify

In a conversation, ask:

Tell me about my Catio session
