MentionsAPI

What is MentionsAPI?

MentionsAPI tracks brand visibility across AI search surfaces — ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews, Google AI Mode, and Bing Copilot. This MCP server puts that data inside any MCP-compatible client, letting you ask in plain English and get structured data back.

How to use MentionsAPI?

Connect via a remote server (recommended, zero install) at https://api.mentionsapi.com/mcp using OAuth or a Bearer token (API key). For local usage, run npx -y @mentionsapi/mcp@latest and configure the API key as the MENTIONSAPI_KEY environment variable. Set up in claude.ai, Claude Code, Cursor, Windsurf, or ChatGPT Plus using provided configuration examples.

FAQ from MentionsAPI

How do I get started with MentionsAPI?

Sign up for free (no card required, get $1 credit) at https://mentionsapi.com/signup, mint an API key at https://mentionsapi.com/app/keys, connect via remote or stdio server, then ask your AI agent to use mentions_check or another tool.

ChatGPT, Claude, Gemini, Perplexity, Google AI Overviews, Google AI Mode, and Bing Copilot. The quick mode calls all four LLM APIs in parallel.

How much does MentionsAPI cost?

Pay-as-you-go only, no subscriptions or minimums. mentions_check starts at $0.02 (cached, quick mode) or $0.39 fresh. Other tools range from $0.50 to $1.50. A $1 free credit is provided on signup, and the minimum top-up is $5.

What happens if my API key is missing or invalid?

The server starts without a key and returns structured errors (auth_required, auth_invalid, insufficient_balance, rate_limit_exceeded) that the AI agent can relay in plain English, including signup and top-up URLs.

What are the runtime requirements for the local server?

The stdio server requires Node.js (via npx) and a MENTIONSAPI_KEY environment variable. The remote server requires only an MCP-compatible client and an API key.
