MentionsAPI MCP Server
Ask your AI agent whether AI recommends your brand. MentionsAPI tracks brand visibility across every AI search surface β ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews, Google AI Mode, and Bing Copilot β and this MCP server puts that data inside any MCP-compatible client.
Ask in plain English. Get structured data back.
