Free MCP Tools

Browser-based utilities for working with Model Context Protocol configs. Nothing you paste in ever leaves your device.

Config Generator

Build a ready-to-paste claude_desktop_config.json (or Cursor/VS Code/Windsurf equivalent) from servers in the directory or your own custom setup.

Paste your MCP config JSON and catch syntax errors and missing fields before you restart your client.

Estimate how much of your model's context window your installed MCP servers' tool schemas are using.
