Cotlet

Cotlet, run by Take Group sp. z o.o. in Katowice, Poland, gives AI agents access to apps that have no usable API or MCP server. Users sign in to each app once in their own cloud-hosted Chrome, enable it for agents, and the agent then works in that account through one hosted MCP server or a REST API. The catalog on the homepage lists 306 apps, and the GitHub README lists 259 apps in 11 categories.

What It Is

Cotlet is a hosted bridge between AI agents and signed-in web apps. Each user gets a Cloud Browser, a personal Chrome instance in the cloud, one per app, on a residential IP in the country they choose. The user logs in there personally, passes any CAPTCHA or MFA checks, and presses Enable for agents as read only or read and write. Cotlet says it never saves passwords and stores the signed-in profile encrypted.

Cotlet builds and maintains the tools for each app in its catalog. Each app is exposed as a read tool and a write tool over MCP, such as skool_read and skool_write, and the same operations are available as REST endpoints.

How the Workflow Runs

A user signs up, picks apps, signs in to them in the Cloud Browser, and adds the MCP URL to an agent, for example with a claude mcp add command. Agents can then ask for tasks such as counting new community members, moving bookings, sending invoices or pulling reports. Calls send the same requests the browser would, and each is listed in a Background activity log. When no tool covers a task, the agent can drive the Cloud Browser itself through MCP browser tools or Chrome DevTools sessions with Playwright or Puppeteer.

Access Controls and Reliability

API keys can be scoped to specific apps and to read-only or read-write access. Actions that reach other people, such as posts and messages, wait for user approval by default. Cotlet states it tests every integration every 6 hours, pauses ones that break, and does not charge for failed calls. It says it does not solve CAPTCHAs, bypass MFA, or automate LinkedIn, Instagram or unlicensed banks.

Clients and Integrations

The docs and README describe setup for Claude Code, Claude Desktop, ChatGPT, Cursor, Codex, Cline, n8n, Make, Zapier and any MCP client. Node.js and Python SDKs and a CLI are listed in the docs. The GitHub repository hosts documentation, and Cotlet also links self-hosted, noncommercial Python servers for some individual apps.
