Overview

AI-generated overview

Remote captcha-solving service that lets an assistant submit captcha tasks, poll for results, and check account balance.

What you can do
  • Create captcha-solving tasks for a target page and site key
  • Poll a submitted task until a result is returned
  • Check the account balance for the service
  • Supports 19 task types using the createTask / getTaskResult protocol, with requests rendered in a real browser and anti-bot handling built in
When to use it
Useful when an assistant or automation pipeline needs captcha tokens for pages it is allowed to access and you would rather pay a hosted service than run solving infrastructure or proxies yourself.
Requirements
A remote Streamable HTTP endpoint; no local runtime needed for the remote option. A DataLeads client key (clientKey) is required, and a paid or free-tier account is needed; an optional Docker stdio variant takes the key via the DATALEADS_API_KEY environment variable. Network access to the service is required.
Before you install
The client key is a billable credential and should be kept secret. Usage is metered against paid tiers after the free allowance, so tasks can cost money. Submitting page URLs and site keys sends that data to a third party, and solving captchas may conflict with the terms of the sites involved.

Installation

In SourceWeft

  1. Open Captchaflow in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.DataLeadsPRO%2Fcaptchaflow/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.
