Overview

AI-generated overview

Remote MCP server that lets an assistant solve reCAPTCHA v2/v3, hCaptcha, Cloudflare Turnstile and image captchas, returning tokens for the target site.

What you can do
  • Solve reCAPTCHA v2, reCAPTCHA v3 (with a page action), hCaptcha and Cloudflare Turnstile challenges, returning a token to submit to the target site
  • Solve distorted-text image captchas from a base64 image and get the recognized text back
  • Look up the result of an existing captcha task by task_id, including batched lookups
  • Check platform and adapter versions, and send bug reports or feedback
  • Inspect connection status, connected accounts and installed toolkits, and search or describe MCPs in the platform marketplace
  • Authenticate the server with a browser-issued access token, either as a header or a session-only login
When to use it
Useful when an assistant has to get past captcha challenges on sites it is automating or testing and you are willing to pay per solve. Not needed for tasks that never encounter captcha gates.
Requirements
A remote streamable HTTP endpoint; no local package or runtime. No credentials are declared in the manifest, but the authenticate tool expects an access token from a browser login, supplied as an Authorization Bearer header or pasted for a session-only login. Network access to the hosted endpoint.
Before you install
Each solve is billed in prepaid credits, so automated use spends money. Solving captchas can violate the terms of service of the sites involved and is often used to bypass anti-bot protections; check that your use is legitimate. The authenticate tool asks for an access token, and report_bug sends recent conversation messages for reproduction.

Installation

In SourceWeft

  1. Open Captcha Solver 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.mcp-dir%2Fcaptcha-mcp/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

Takes no parameters.

toolkit_info

Takes no parameters.

marketplace

Marketplace

The official mcp.ai marketplace — the in-platform catalog of every MCP/tool, AND the way to run them. Covers capability requests like "find an MCP that does X", "consulta um CPF", "is there a tool for Y". Core flow: action=search discovers MCPs by intent → describe returns one MCP's full profile (every tool with its id + params, pricing, auth) so you pick the right tool_id → invoke RUNS that tool. KEY: invoke works even when the MCP is NOT installed — it runs the tool pontualmente (one-off), without adding the MCP to the toolkit and without bloating the tool list. If the MCP needs a credential/login, invoke returns a connect link; if it is paid and the wallet is empty, invoke returns a checkout/top-up link (the user opens it, then you retry). Use install only to make an MCP PERMANENT in the active toolkit (its tools then show up natively in future sessions); prefer invoke for a single/occasional use. list_tools lists what is callable right now. subscribe/cancel handle per-MCP billing; report_bug sends feedback; request_mcp asks us to build a NEW MCP when nothing fits. Search/describe flag installed_in_toolkit vs installed_in_workspace. Writes (install/uninstall/subscribe/cancel and the one-off install behind invoke) require workspace owner/admin. It also carries the mcp.ai PROMPT LIBRARY, which is about ready-made prompt TEXT rather than MCPs: search_prompts finds one, get_prompt returns its full text with {{variables}} filled, and publish_prompt saves a prompt and returns a shareable mcp.ai/p/<slug> link that opens without login.

authenticate

Authenticate

MCP.AI for IDE agents (Cursor, etc.): log in in the browser, copy the access token. Best: add it to this server's config as a header `Authorization: Bearer <token>` for a permanent, non-expiring connection. Or paste it here for a session-only login: call with { token: "<jwt>" } after the user pastes, or with no args to get the link.
