Questions
Common questions, short answers.
What is Cubeshell?
Cubeshell is one MCP connection that gives your AI tools access to many paid APIs. You keep one prepaid credit balance and pay per call instead of holding a subscription for every tool.
How does pricing work?
Start with $49 for 1,000 Cubeshell credits. Each tool costs its own number of credits. You see the price before a call runs and get a receipt after.
Is there a monthly subscription?
No. There are no plans, seats, or monthly fees. You top up credits when you want and spend them only when a tool runs.
Do credits expire?
No. Credits you buy never expire. Top up once and spend them whenever you actually use a tool.
How do I connect it to Claude or Codex?
Add your Cubeshell connection URL to your client's MCP settings and approve it once. That works in Claude, Codex, Cursor, Replit, and any other MCP client.
What is MCP?
MCP stands for Model Context Protocol, an open standard that lets AI tools call outside services. Cubeshell is an MCP server, so anything that speaks MCP can use the tools it offers.
Which tools are available?
All the tools on this page are available now. We keep adding new ones, and you choose which tools your workspace can use.
Can I control what tools run and what they spend?
Yes. You choose which tools are enabled, the order they are tried in, and the maximum spend. Nothing is charged without an explicit billable rule.
Stop paying for tools you barely use.
Connect once, add credits, and pay only when something runs.
