Questions, answered

no accounts · no backend
Are these tools really free?

Yes. Every tool here runs as a static page in your browser — no account, no paywall, no usage counter. If it ever needs a server, we will label it.

Do you store or upload my configs?

No. Paste, convert, and validation all execute in client-side JavaScript on your device. Your servers, commands, and env values never leave the tab.

Is there a backend or an account system?

No backend and no accounts. These pages have no database, no login, and no analytics tied to your input. Close the tab and your data is gone.

Which MCP clients are supported?

The converter maps between Claude Desktop, Cursor, VS Code, Claude Code, Codex CLI, Windsurf, Gemini CLI, and Cline — using widely-known structural shapes only, never invented required fields.

What if my client changed its format since this shipped?

Clients drift. Treat every output as structural and verify against your client's current docs before pasting it anywhere important.
