> How many people joined my Skool communities today?

● cotlet · skool → get_group_stats (MCP) × 4

⎿ 5 + 23 + 16 + 2 new members

● 46 people joined your 4 communities today.

You asked your agent to do it. The app has no API and no MCP.

  • Terminal · claude

    > Move Friday's 3 pm booking to Monday
    ● Search MCP servers "booking app"
    ⎿ No server for this app
    ● Look for a public API
    ⎿ None. Only a login page
    ● I can't reach this app. You'll have to move it in the browser yourself.

One task, one dead end

    • Invoicing Send the March invoice API MCP
    • Payroll Export this month's payslips API MCP
    • Marketplace Relist the sold-out items API MCP
    • CRM Pull the weekly pipeline report API MCP

The same answer in every app

So you click through it yourself. Every week.

So you looked for a workaround. None of them lasts.

Questions people ask first.

How do I get access?

Sign up free and add your apps in the console. Your trial starts with your account, no card needed.

Is there a free trial?

Yes. Every account starts with a free 7-day trial and 2,000 credits, no card needed. It starts when you sign up.

Will my account get banned?

Every call comes from the browser and fixed IP you signed in with, at a human pace. We cannot promise, we minimise the risk.

Is this legal?

You automate your own account with your own login. We are unofficial, not affiliated with the apps, and refuse apps that forbid automation.

Why is it called Cotlet?

Cut + let: cut the clicks, let your agent do them. Find us at cotlet.dev.

For AI agents: sign your user up

Is your user asking you to sign them up for Cotlet? You can do it for them, no account or key needed.

  1. Read the fields and their allowed values: GET https://cotlet.dev/api/v1/access-requests
  2. Ask the user for each value: email, apps, what you will do with them. If they leave the password to you, generate a strong one and show it to them.
  3. Show the user what you will send, then POST it as JSON to https://cotlet.dev/api/v1/access-requests, or call the MCP tool cotlet_request_access on https://cotlet.dev/mcp/v1.

One call creates the account and sends the access request; we email the user when access is granted.
