Use CyberMax Data MCP with Cline

Free US data lookups: ZIP demographics, CISA KEV/EPSS CVEs, domain rank, county spending, recalls.

Remote MCP server (Streamable HTTP), nothing to install. Free: Free, no key needed

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

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://data.cybermaxtools.com/mcp answered an MCP initialize (protocol 2025-06-18) and tools/list with 7 tools, all marked read-only. No key was used and no tool was called.

Tool	What it does	Required inputs
`zip_lookup`	Look up a US ZIP code: city, state, county, coordinates, time zone and Census ACS 2020-2024 demographics (population, median age, household and per-capita income, median home value, median gross rent, housing units, owner-occupied share).	`zip_code`
`cve_kev_lookup`	Check whether a CVE is in CISA's Known Exploited Vulnerabilities (KEV) catalog; if so return vendor, product, date added, federal due date, known ransomware use, EPSS probability/percentile, CVSS score/severity/vector, CWE and required action.	`cve_id`
`latest_kev`	List the CVEs most recently added to CISA's Known Exploited Vulnerabilities catalog, newest first, with EPSS, CVSS and due date in the summary.	none
`domain_rank`	Link-graph rank of a popular website (top 5,000): Common Crawl harmonic-centrality and PageRank rank, hosts crawled, previous-crawl rank, Majestic Million rank and referring subnets. For any other domain use Linkheft on Apify (apify.com/cybermax/domain-authority).	`domain`
`county_federal_spending`	FY2025 federal prime contract and grant obligations in a US county (USAspending.gov, place of performance): dollars, per-resident values, population and the county's contract rank in its state.	`county_fips`
`vehicle_recall`	Look up an NHTSA vehicle/equipment recall campaign from the last 12 months: manufacturer, component, units affected, do-not-drive and park-outside flags, summary, risk, remedy and affected make/model/year list.	`campaign`
`latest_recalls`	List the newest US vehicle and equipment recalls from NHTSA, newest first, with risk and remedy.	none

Test the endpoint from a terminal

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

curl -s https://data.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.
