Install

Use the official LangChain MCP adapter:

pip install langchain-mcp-adapters langgraph langchain-anthropic

The adapter loads any MCP server's tools as native LangChain tools.

Use Trends MCP as LangChain tools

import asyncio, os
from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent

async def main():
    client = MultiServerMCPClient({
        "trends-mcp": {
            "transport": "streamable_http",
            "url": "https://api.trendsmcp.ai/mcp",
            "headers": {"Authorization": f"Bearer {os.environ['TRENDS_MCP_API_KEY']}"},
        }
    })

    tools = await client.get_tools()
    agent = create_react_agent("anthropic:claude-3-5-sonnet-latest", tools)

    result = await agent.ainvoke({
        "messages": [{
            "role": "user",
            "content": "Compare YouTube and TikTok 1 year trend for 'Stanley cup'.",
        }]
    })
    print(result["messages"][-1].content)

asyncio.run(main())

Set the API key in your shell:

export TRENDS_MCP_API_KEY=YOUR_API_KEY

The exact LangChain MCP adapter API can change, see python.langchain.com for the current reference.

Use the REST API directly

You can also skip MCP and call the REST API as a regular LangChain Tool or just use requests inside any chain.

import requests
from langchain_core.tools import tool

@tool
def get_trend(source: str, keyword: str) -> dict:
    """Get a 5-year trend time series for a keyword on a given source."""
    return requests.post(
        "https://api.trendsmcp.ai/api",
        headers={"Authorization": "Bearer YOUR_API_KEY"},
        json={"source": source, "keyword": keyword},
        timeout=30,
    ).json()

Three tools your AI gets

• get_trends, historical time series for any keyword on any source (5 years weekly, 30 days daily where supported).
• get_growth, percentage change over any period (7D, 1M, 3M, 6M, 1Y, YTD, custom dates).
• get_top_trends, what is trending right now across live platform feeds.

All data sources in one connection

One API key gives your LangChain agent every keyword source and every live feed below.

Keyword sources (Get Trends and Get Growth)

source	What it measures	Keyword format
google search	Google search volume	Any keyword or phrase
google images	Google image search volume	Any keyword or phrase
google news	Google News search volume	Any keyword or phrase
google shopping	Google Shopping search volume	Any keyword or phrase
youtube	YouTube search volume	Any keyword or phrase
tiktok	TikTok hashtag volume	Hashtag or topic
reddit	Subreddit subscribers	Subreddit name only, no r/ prefix
amazon	Amazon product search volume	Product name or category
wikipedia	Wikipedia page views	Article title or topic
news volume	News article mention volume	Any keyword or phrase

app downloads	Mobile app download estimates (Android)	Package id or app identifier
npm	npm package weekly downloads	Exact package name e.g. react
steam	Steam concurrent players (monthly)	Game display name e.g. Elden Ring

All values are normalized to a 0 to 100 scale where the pipeline supports it, so you can compare different sources directly.

Live leaderboards (Get Top Trends)

Google Trends, Google News Top News, TikTok Trending Hashtags, YouTube Trending, X (Twitter) Trending, Reddit Hot Posts, Reddit World News, Wikipedia Trending, Amazon Best Sellers Top Rated, Amazon Best Sellers by Category, App Store Top Free, App Store Top Paid, Google Play, Top Websites, Spotify Top Podcasts, Steam Most Played, GitHub Trending Repos, IMDb MOVIEmeter, Trending Books.

Use cases for LangChain and LangGraph agents

• Research agents. Ask the agent to pull a multi-source trend, do the comparison, and write the brief in one flow.
• Pytrends alternative. Drop in for unofficial Google Trends scrapers without the rate limits and HTML parsing.
• Market intelligence agents. Compare brand search across Google, YouTube, TikTok, Reddit, and Amazon.
• Investment alpha agents. Combine news sentiment, Reddit growth, and Wikipedia views as alternative data signals.
• Content strategy agents. Use TikTok and YouTube trend deltas to pick the next topic to publish.
