## Frequently Asked Questions <a id="cite-faq"></a>

### Why does distinguishing a UK Limited Company from a Sole Trader matter for B2B email?
Under UK PECR Regulation 22, unincorporated sole traders and traditional partnerships have the same legal status as individual consumers—meaning you cannot send them cold marketing emails without prior consent. Limited companies (Ltd, PLC) and LLPs are corporate subscribers where B2B legitimate-interest outreach is lawful.

### Can AI agents call TokenEnrich directly via MCP?
Yes. TokenEnrich exposes both a standard REST JSON API and a native Model Context Protocol (MCP) tool interface so Claude, OpenAI, and custom LangGraph agents can enrich domains autonomously.
