## Install

### Claude Desktop (claude_desktop_config.json)

```json
{
  "mcpServers": {
    "qveris": {
      "command": "npx",
      "args": [
        "-y",
        "@qverisai/mcp"
      ],
      "env": {
        "QVERIS_API_KEY": "your-value"
      }
    }
  }
}
```

Settings > Developer > Edit Config. macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\. Restart Claude Desktop afterwards.

### Claude Code

```sh
claude mcp add --env QVERIS_API_KEY=your-value --transport stdio qveris -- npx -y @qverisai/mcp
```

### Cursor (.cursor/mcp.json)

```json
{
  "mcpServers": {
    "qveris": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@qverisai/mcp"
      ],
      "env": {
        "QVERIS_API_KEY": "your-value"
      }
    }
  }
}
```

Project file; use ~/.cursor/mcp.json to enable it in every project.

### VS Code (.vscode/mcp.json)

```json
{
  "inputs": [
    {
      "type": "promptString",
      "id": "qveris_api_key",
      "description": "QVERIS_API_KEY",
      "password": true
    }
  ],
  "servers": {
    "qveris": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@qverisai/mcp"
      ],
      "env": {
        "QVERIS_API_KEY": "${input:qveris_api_key}"
      }
    }
  }
}
```

### Claude Code (remote)

```sh
claude mcp add --transport http qveris "https://mcp.qveris.ai/mcp"
```

The same server is also hosted as a remote MCP endpoint, so nothing runs on your machine.
