Cotlet hosts MCP servers and REST APIs for web apps that have no official API, or only a narrow one. You sign in to each app once, in your browser; Cotlet keeps only the encrypted session, never your password. Your AI agent then works in your own account and does the clicking for you.

  • One MCP server for every app: https://cotlet.dev/mcp/v1. Works with Claude, ChatGPT, Cursor, Codex, GitHub Copilot, Gemini, Windsurf, n8n and any MCP client.
  • A REST API with the same actions for scripts: https://cotlet.dev/api/v1. One key for both.
  • 97 apps today, including Skool, Substack, Medium, Udemy, Teachable, Booksy, Fresha, GetYourGuide, Idealista and Dubsado.
  • No stored passwords, no CAPTCHA solving, no MFA bypass. Hosted in the EU.
