Use Swellmeter Trending MCP with Cursor

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

Open or create the mcp.json file (global or per project).
Add the server under "mcpServers" as shown and save.
Open Cursor's settings, find the MCP section and check that the server is enabled and lists its tools.
Ask the agent a question the tools can answer and approve the tool call.

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "swellmeter-api": {
      "url": "https://swellmeter-api.cybermaxtools.com/mcp?via=use-with-cursor"
    }
  }
}

With a paid key:

{
  "mcpServers": {
    "swellmeter-api": {
      "url": "https://swellmeter-api.cybermaxtools.com/mcp?via=use-with-cursor",
      "headers": {
        "x-api-key": "${env:CYBERMAX_API_KEY}"
      }
    }
  }
}

Cursor fills ${env:CYBERMAX_API_KEY} from your environment, so the key never sits in the file.

Where it goes:

~/.cursor/mcp.json (every project)
.cursor/mcp.json (this project only)

Config format checked 2026-10-09 against Cursor's MCP documentation.

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

Cursor uses the top-level key "mcpServers" (VS Code uses "servers"); a file copied from VS Code will not load.
After editing the file, toggle the server off and on in settings if the tools do not appear.
The free tier has a daily limit (see the pricing line above); a paid key raises it.
