FAQ
Common questions
What is Cubeshell?
Cubeshell is one MCP connection that gives your AI agent every tool it needs: email verification, email finding, company and people data, phone numbers, web scraping, and more. There is no subscription. You keep one prepaid credit balance and pay only when a tool runs.
How does Cubeshell pricing work?
Cubeshell has no subscription. You start with $49 for 1,000 credits, every tool has a fixed credit price you see before it runs, and you get a receipt after. Credits never expire.
Is there a monthly subscription?
No. Cubeshell has no plans, seats, or monthly fees. You top up credits when you want and spend them only when a tool runs.
Do I get free credits when I sign up?
Yes. Every new account starts with 20 free credits, enough for your agent to run real tools before you pay anything. No card needed. When they run out, top up once and keep going.
Do credits expire?
No. Cubeshell credits never expire. Top up once and spend them whenever you actually use a tool.
How do I connect Cubeshell to Claude or Codex?
Create an API token and paste the ready-made command into Claude or Codex. You can also connect with your workspace URL and sign in once.
What is MCP?
MCP stands for Model Context Protocol, an open standard that lets AI agents call outside services. Cubeshell is an MCP server, so anything that speaks MCP can use every Cubeshell tool.
Which tools does Cubeshell offer?
Cubeshell covers Email (verify and find addresses), Company (search, technology lookups, similar companies), People (profiles and employee search), Contact (mobile numbers), Signals (job changes and job postings), and Web (scraping and screenshots). New tools are added to the same connection, nothing to set up.
Is there an email verification API without a subscription?
Yes. Cubeshell verifies email addresses pay per use: your agent checks an address, you pay a fixed credit price for that check, and there is no plan or monthly fee.
Is there a pay-as-you-go web scraping API?
Yes. Cubeshell's web scrape and screenshot tools are pay as you go. Your agent fetches a page or takes a screenshot, you pay for that run, and that is all.
Can I control what a tool call spends?
Yes. Every call shows its price before it runs, you can set a spend ceiling on any call, and your prepaid balance is the hard limit. A call that returns nothing billable costs nothing.
Stop paying for tools you barely use.
