Use Swellmeter Trending MCP with Cline

Google trending searches API + MCP: 30 countries, day lists, 30-day history. $5 pack; 50 free/day.

Remote MCP server (Streamable HTTP), nothing to install. Free: 50 free calls/day · Paid: $5 pack; $19/mo

Set it up

Click the MCP Servers icon in Cline's toolbar, open Configure and click Configure MCP Servers.
Add the server under "mcpServers" with "type": "streamableHttp" and save.
Check that the server is enabled and lists its tools.
Every tool here is read-only, so you can add tool names to "autoApprove" if you want Cline to run them without asking.

Add to cline_mcp_settings.json::

{
  "mcpServers": {
    "swellmeter-api": {
      "type": "streamableHttp",
      "url": "https://swellmeter-api.cybermaxtools.com/mcp?via=use-with-cline",
      "disabled": false,
      "autoApprove": []
    }
  }
}

With a paid key:

{
  "mcpServers": {
    "swellmeter-api": {
      "type": "streamableHttp",
      "url": "https://swellmeter-api.cybermaxtools.com/mcp?via=use-with-cline",
      "headers": {
        "x-api-key": "YOUR_KEY"
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}

The settings file is local to your machine; do not paste it into a shared repository with the key in it.

Where it goes:

cline_mcp_settings.json: in the IDE, click the MCP Servers icon › Configure › Configure MCP Servers
CLI: ~/.cline/data/settings/cline_mcp_settings.json

Tools you get

Endpoint checked 2026-10-09: https://swellmeter-api.cybermaxtools.com/mcp answered an MCP initialize (protocol 2025-06-18) and tools/list with 5 tools, all marked read-only. No key was used and no tool was called.

Tool	What it does	Required inputs
`trending_now`	Newest Google trending searches for 1-5 countries (ISO-2 codes): query, approximate traffic, start time, first seen today, other countries where it trends, news links.	`geo`
`trending_day`	Every trending search seen on one UTC day (today or the last 30 days) for 1-5 countries, biggest first, with first/last seen, peak traffic and news.	`geo`
`cross_country_trends`	Topics trending right now in 2+ of the 30 countries, most countries first.	none
`topic_history`	Search the last 30 days of trending searches for a topic; returns each matching search with the countries, first seen, last day seen and peak traffic.	`q`
`countries`	The 30 country codes, names and last read time.	none

Test the endpoint from a terminal

This lists the tools without a key and without calling any of them:

curl -s https://swellmeter-api.cybermaxtools.com/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

If it does not work

The field is "type" (not "transportType") and the approval list is "autoApprove".
Set "type": "streamableHttp" explicitly; "sse" is the legacy transport.
The free tier has a daily limit (see the pricing line above); a paid key raises it.
