Plain answers about AI search for business owners: the Preferly blog and the guides by topic and industry.

Use Preferly from your AI agent

These checks also run as an MCP server, so any AI agent or assistant that supports MCP can call them. Connect to https://www.preferly.ai/mcp (streamable HTTP). Add ?client= with your agent’s name so we can tell clients apart, for example:

{
  "mcpServers": {
    "preferly": {
      "url": "https://www.preferly.ai/mcp?client=<your-agent>"
    }
  }
}

Step-by-step setup for Claude, ChatGPT, Cursor, VS Code and more: Preferly MCP server.

Recognized names: hermes, claude, cursor, codex, openclaw, vscode, goose, smithery, monid, windsurf, gemini, cline, zed, chatgpt-dev. Any other MCP client works without one.
