Or add it to settings.json yourself::

{
  "mcpServers": {

Tools you get

Endpoint checked 2026-10-09: https://bonafido.cybermaxtools.com/mcp answered an MCP initialize (protocol 2025-06-18) and tools/list with 1 tool, all marked read-only. No key was used and no tool was called.

Tool	What it does	Required inputs
`verify_domain`	Verify a business domain, URL or email domain: does it resolve, how old is it (RDAP), mail setup (MX/SPF/DMARC), live homepage vs parked/for-sale page, redirects, contact details, company-name match, Wikidata official website and look-alike detection. Returns verdict (verified/likely_legit/unverified/suspicious/not_found), trustScore 0-100, riskFlags and evidence. Pass company_name to check the domain belongs to that company. Up to 5 domains via "domains".	none

Test the endpoint from a terminal

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

curl -s https://bonafido.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

Use "httpUrl" for Streamable HTTP; "url" is for the older SSE transport.
The docs note that for unpaid-tier and Google One users, Gemini CLI was replaced by Antigravity CLI on 18 June 2026.
The free tier has a daily limit (see the pricing line above); a paid key raises it.
