Overview

What is Google Trends MCP?

Google Trends MCP is a Model Context Protocol server that gives AI assistants structured Google Trends data. It supports batch keyword research (up to 50 keywords per batch), cross-batch normalization for comparability, and production-level SaaS deployment. Built with FastMCP, it works with Claude Desktop, ChatGPT, Cursor, Perplexity, and other major AI clients.

How to use Google Trends MCP?

Install Python 3.11+, clone the repo, create a virtual environment, install dependencies, then run python server.py for local stdio mode. For a web service, use --transport streamable-http with host and port. Deploy publicly with Docker Compose. Configure client MCP entries with the endpoint URL and an API key (obtained from the dashboard after Google OAuth login).

Frequently asked questions

1

What should I do if I hit a Google Trends 429 rate limit?

The server has built-in 1–3 second random delays and backoff retries. If you still hit limits, reduce call frequency, set an HTTPS proxy, or switch to the `trendspy` provider.

2

Why can’t I use print() in stdio mode?

In stdio mode, `stdout` carries MCP JSON-RPC protocol messages; ordinary text would break the protocol. Logs must be written to `stderr`. Only `--smoke-test` mode allows JSON output to stdout.

3

How is compare_keywords different from research_keywords?

`compare_keywords` returns raw Google Trends batch-relative scores for up to 5 keywords. `research_keywords` returns cross-batch normalized estimates using an anchor keyword, suitable for directional research across many keywords.

4

How fast is a batch research request?

With 2–4 concurrent threads and random delays, 10 keywords take about 5–10 seconds; 50 keywords take about 15–30 seconds. In-process caching (default 15 minutes) skips network calls for repeated requests.

5

What if I don’t have Google OAuth for local development?

When `GOOGLE_CLIENT_ID` is not set, the server enters dev mode. Visit `/auth/dev-login` to log in with a virtual account — no Google account needed.
