About MCP 2026 Check

MCP 2026 Check is an independent, free web project built to help developers convert, validate, and understand MCP client configuration files. It is designed for developers configuring Model Context Protocol servers for Claude, Cursor, VS Code, Codex, and Gemini. The tool runs without an account and aims to turn a narrow technical task into a clear, repeatable workflow.

What this site provides

Every converter and guide is tested against representative configuration examples. Explanations identify client-specific differences instead of hiding them behind a generic conversion button.

Where practical, processing happens locally in the browser. That design improves speed and reduces unnecessary collection of technical material. The project is not affiliated with Google, Anthropic, Microsoft, OpenAI, or the maintainers of any protocol mentioned unless a page explicitly says otherwise.

Editorial principles

• Explain checks and outputs in plain English.
• Keep examples useful, reproducible, and free of real credentials.
• Update material when the underlying specifications or common tools change.
• State important limitations instead of presenting automated output as professional advice.
