2Captcha is a service for automated CAPTCHA solving in your apps. It helps developers bypass CAPTCHAs quickly and reliably.

Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Twocaptcha account to Claude via Composio Connect, enabling it to solve image CAPTCHA for login automation, bypass reCAPTCHA on registration form, solve hCaptcha for ticket booking bot, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

3. Connect your Twocaptcha account

Back in Claude, ask it to connect to Twocaptcha or give it any Twocaptcha-related task.

For example, ask Claude to:

  • "Solve image CAPTCHA for login automation"
  • "Bypass reCAPTCHA on registration form"
  • "Solve hCaptcha for ticket booking bot"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Twocaptcha account is ready to use.

What is the Twocaptcha Claude Connector, and what's possible with it?

The Twocaptcha MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Twocaptcha account. It provides structured and secure access to 2Captcha's automated CAPTCHA-solving services, so your agent can initiate, monitor, and manage CAPTCHA-solving tasks for a variety of applications on your behalf.

  • Automated CAPTCHA solving: Instantly create new CAPTCHA-solving tasks for supported CAPTCHA types, letting your agent bypass complex verification challenges.
  • CAPTCHA task management: Monitor the status of active CAPTCHA tasks and retrieve results as soon as they're solved.
  • Flexible CAPTCHA parameter handling: Pass specific parameters and configuration options to handle different CAPTCHA types, including image, audio, and reCAPTCHA challenges.
  • Integration with automation workflows: Seamlessly plug CAPTCHA-solving into larger automated processes, reducing manual intervention for form submissions, scraping, and more.
  • Error detection and retry logic: Enable your agent to handle failed CAPTCHA attempts and automatically trigger retries or alternative logic as needed.

Troubleshooting

1. Why does Claude not use the Composio connector for Twocaptcha?

The connector can show as connected, but Claude must use it in each Twocaptcha conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Twocaptcha again.

2. Why does Claude show an MCP server error before Twocaptcha connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Twocaptcha.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Twocaptcha.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Twocaptcha authorization link not work?

The Composio connector is one server. Your Twocaptcha account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Twocaptcha connection.
  • Composio creates a fresh Twocaptcha authorization link.
  • Open that link in your browser and finish the Twocaptcha sign-in.

4. Why do Twocaptcha actions fail after they worked before?

The Twocaptcha connection can expire or lose permission.

  • Ask Claude to inspect the Twocaptcha connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Twocaptcha account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Twocaptcha.
  • If the action still fails with a permission error, check that the connected account has that permission in Twocaptcha itself.

5. How do I switch to a different Twocaptcha account?

Claude can manage the Twocaptcha connection for you.

  • Ask Claude to disconnect or delete the current Twocaptcha account.
  • Ask Claude to connect Twocaptcha again.
  • Open the new Composio authorization link for Twocaptcha.
  • Sign in with the other Twocaptcha account in the browser.
  • After the account connects, ask Claude to retry the Twocaptcha task.

6. Why is my Twocaptcha connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Twocaptcha connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Twocaptcha tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Twocaptcha.

FAQ

Frequently asked questions

With a standalone Twocaptcha MCP server, the agents and LLMs can only access a fixed set of Twocaptcha tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Twocaptcha and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Twocaptcha tools.

Yes, absolutely. You can configure which Twocaptcha scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Twocaptcha data and credentials are handled as safely as possible.
