Install the Hologrow MCP server and test the connection.

Connection details:
- Name: Hologrow
- URL: https://mcp.hologrow.ai/mcp
- Transport: Streamable HTTP
- Authentication: API Key
- Header: Authorization: Bearer {apiKey}

Requirements:
1. Add Hologrow using this client's native MCP configuration. Use API Key authentication only; do not use OAuth.
2. Make only the changes required for installation. Keep the API key secret and do not repeat, log, or include it in your response.
3. After installation, call Hologrow's list_platforms tool once. Do not call any other tools.
4. If successful, list the connected data platforms exactly as returned. If installation, authentication, connection, or the tool call fails, stop and explain the error.

Use Hologrow’s list_platforms tool to list my connected data platforms. Do not call any other tools.
