    Why it is in this group

    • The name "trends___get_growth" says "get": a word for reading.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Point-to-point growth for a keyword on one or more sources. Each window is a preset string (12M, 3M, YTD, and the other listed periods). Values are on a 0-100 scale, plus absolute volume when available. Designed for growth questions; for charting or custom math, get_time_series provides the full series. app downloads and app rankings are keyword sources (Android bundle ID). They are not the App Store / Google Play live boards on get_top_trends. Returns a plan-limit message when the request is rate limited or the monthly quota is used up.

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Full historical series for one keyword and one source (0-100 values, plus volume when available). Suited for charting or custom math. Live 'what's trending now' boards are on get_top_trends. get_growth answers most growth questions with less data. Returns a plan-limit message when the request is rate limited or the monthly quota is used up.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    • untrusted-inputThe name "trends___get_top_posts" says "get" and "post": it reads posts, which other people can write.
    • untrusted-inputThe description's first sentence says "post": it reads posts, which other people can write.
    Description, as the server wrote it
    Live top posts for one hashtag on one social source. Fetched live on every call; nothing is stored. For when the user already has a hashtag and wants the posts winning on it. get_top_trends ranks the hashtags themselves. Returns a plan-limit message when the request is rate limited or the monthly quota is used up.

    Why it is in this group

    • The name "trends___get_top_trends" says "get": a word for reading.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Live top-trending board for exactly one feed type. No keyword. For 'Amazon Best Sellers by Category', 'Google Trends by Category', 'Top Websites', 'Substack by Category', and 'TikTok Trending Hashtags by Category', category selects the board. Default sort is current rank. Use sort='rank_change' for climbers vs a prior snapshot (window 1d, 3d, 7d, 14d, or 30d). If the requested board is not in the database yet (for example a country that is not collected on the schedule), the board is fetched live. App Store Top Free, App Store Top Paid, and Google Play are live store boards, not keyword lookups. App history is available via get_growth or get_time_series with source app downloads or app rankings and an Android bundle ID. Live boards are only available here, not via get_time_series. Returns a plan-limit message when the request is rate limited or the monthly quota is used up.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write4
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Install

Pinned to version 1.0.2. Values in angle brackets are yours to fill in.

claude mcp add --transport http npm https://npm.api.trendsapi.ai/mcp --header 'Authorization: <your-authorization>'

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__npm__trends___get_growth",
      "mcp__npm__trends___get_time_series",
      "mcp__npm__trends___get_top_posts",
      "mcp__npm__trends___get_top_trends"
    ],
    "ask": [],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as npm. Review it before you use it.
