Proofsource and Grok: ask about your brand, get the proof
Add the Proofsource MCP server to Grok and ask about your brand's AI visibility in plain words: who gets named, which sources are cited, what to fix. Developers can also call the same tools from an xAI API agent. Grok is one of the ten engines Proofsource checks, too.
