What is an MCP server?

MCP (Model Context Protocol) is an open standard through which AI agents like Claude or Cursor use external tools. An MCP server gives your agent new capabilities: reading bank statements, converting accounting files or auditing websites.

Do I need to know how to code?

No. You press a button in Claude Desktop, Cursor or VS Code, or copy a block in Codex, Antigravity or Windsurf. You only need to install uv once with a command we provide.

How are credits counted?

Each tool has a fixed cost that the agent sees before using it. Validations and utilities are free. If a call fails, the credit is automatically refunded.

Where is my data processed?

On your own computer. The server runs locally and only contacts KeyFlint to verify the license and deduct credits. Your files do not leave your machine.

What if I run out of credits?

The tool alerts you with a purchase link and nothing is charged. The Pro plan recharges every month; Indie and Agency are one-time purchases.
