# Claude (Web & Desktop)

> Connect Claude.ai and Claude Desktop to your Holistics workspace via MCP.

## Claude.ai

[Claude.ai](https://claude.ai) connects via OAuth — no API key needed.

1. Go to [claude.ai/settings/connectors](https://claude.ai/customize/connectors).
2. Choose **Add custom connector**.

   

3. Enter a name and your [connection URL](/docs/ai/mcp-server/setup#oauth), then click **Add**.

   

4. Click **Connect** and follow the OAuth flow to authenticate with your Holistics account.

   

5. To use it in a chat, make sure Holistics under Connectors is enabled.

   

## Claude Desktop

[Claude Desktop](https://claude.ai/download) uses a local command config.

1. Go to **Settings > Developer > Edit Config**.

   

2. Add Holistics to your config:

   ```json
   {
     "mcpServers": {
       "holistics": {
         "command": "npx",
         "args": [
           "-y",
           "mcp-remote",
           "<MCP_SERVER_ADDRESS>"
         ]
       }
     }
   }
   ```

   For API Key auth, add `"--header", "X-Holistics-Key:<YOUR_HOLISTICS_API_KEY>"` to the `args` array.

3. Save and restart Claude Desktop.
