MCP server
CAPTCHA Solver MCP Server for Claude, Cursor and AI Agents
Give your AI agent a CAPTCHA it can actually get past. CapSkip is a local Model Context Protocol server that solves reCAPTCHA, Cloudflare Turnstile, GeeTest and image CAPTCHAs, with unlimited solving for one flat price.
- Unlimited solves
- Claude, Cursor & more
- Five agent tools
- Runs locally
An AI agent driving a browser is fine until a CAPTCHA appears, and then it simply stops. Vision models do not reliably solve modern challenges, and Playwright MCP, Puppeteer and the other browser-automation servers have nothing to hand the agent when a reCAPTCHA or Cloudflare Turnstile widget blocks the page. The CapSkip MCP server closes that gap. It is a CAPTCHA solver built for AI agents: solving is exposed as ordinary tools the agent calls on its own, mid-task, without you stepping in.
It is a standard Model Context Protocol server published on npm as capskip-mcp, so it works in every MCP client, Claude Code, Claude Desktop, Cursor, VS Code, Windsurf and anything else that speaks the protocol. Five tools cover the ground: solve reCAPTCHA v2, v3 and Enterprise, Cloudflare Turnstile, GeeTest v3, and image or text CAPTCHAs, plus a status tool the agent can call to check the solver is running before it commits to a plan.
The difference from every other CAPTCHA MCP server is what happens to your bill. Solving runs on your own Windows machine or VPS against a flat unlimited licence, starting at a $1 seven-day trial and $10/month, rather than a metered API that charges per solve. That matters more with agents than with scripts: an agent that retries, backtracks and explores will burn through a per-solve balance quickly, while here a retry costs nothing. Nothing about the page leaves your network either, and there is no API key or account to wire in.
No coding required. Run the CapSkip app and the browser extension connects automatically, then solves CAPTCHAs right in the page. Already using another service? Migrating is easy: CapSkip is a drop-in captcha solver that emulates 2Captcha, RuCaptcha, Anti-Captcha, CapMonster Cloud, CapSolver, DeathByCaptcha, SolveCaptcha and Captchas.io. Add your service to the hosts file in the CapSkip app and your existing code is routed to CapSkip and solved locally, with no changes.
Why CapSkip is the best CAPTCHA MCP server
Five tools, every CAPTCHA type
capskip_solve_recaptcha, capskip_solve_turnstile, capskip_solve_geetest and capskip_solve_image_captcha, plus capskip_status so the agent can check the solver before it starts.
Retries cost nothing
Agents explore, backtrack and retry. On a per-solve API that is money; on a flat unlimited licence it is free, so you never have to prompt an agent into being frugal.
Works in any MCP client
Standard stdio MCP server on npm. Claude Code, Claude Desktop, Cursor, VS Code, Windsurf and any other client pick it up from one block of config.
Local, with no API key
The server talks to the CapSkip app on 127.0.0.1. There is no account to create, no key to paste into a config file, and no page content sent to a third party.
Long solves will not time out
The server streams MCP progress notifications while a challenge is being worked on, so a slow reCAPTCHA keeps the client alive instead of tripping its request timeout.
Answers the agent can act on
Every tool returns a structured result with the token, and failures come back as plain guidance the model can read and correct, rather than an opaque error code.
Add CapSkip to your MCP client
Drop this into your client config and five CAPTCHA tools appear in the agent’s toolbox. Not using MCP? The same local solver is reachable three other ways.

}Works in Claude Code, Claude Desktop, Cursor, VS Code and Windsurf. Run the CapSkip app alongside it and the agent solves CAPTCHAs on its own.
No-code browser extension
Install the CapSkip extension and it detects the widget on any page and solves it for you, with nothing to script.
Official SDKs
Automate solving from your own code with the Python, Node.js, PHP and C# clients. A few lines returns a valid token.
Local HTTP API
Prefer raw HTTP? CapSkip exposes a local endpoint with 2Captcha and Anti-Captcha API emulation, so any HTTP client works.
Point your agent at a real challenge
Our demo pages host live reCAPTCHA, Turnstile, GeeTest and image widgets. Wire up the MCP server, ask your agent to get past one, and watch it call the tool and carry on.
How to set up the CAPTCHA solver MCP server
The MCP server is a thin client for the CapSkip app running on your machine, so install the app first, then add the config block above to your MCP client.
-
1
Install CapSkip
Download the desktop app for Windows (or run it on a VPS) and launch it. The local solver starts automatically.
-
2
Sign in to the app
Buy the $1 trial or a Bronze / Silver / Gold license and your login details arrive by email straight away, with the license live the moment you pay. Sign in to the app with them and you are ready to solve. The setup guide walks through it.

How to use a CAPTCHA solver MCP server with your AI agent
Setup takes about two minutes. Install the CapSkip desktop app for Windows and sign in with your licence, because the app is what performs the solving. Then add the capskip entry to your MCP client config: Claude Code reads .mcp.json in the project or your user config, Claude Desktop uses claude_desktop_config.json, and Cursor, VS Code and Windsurf each have their own MCP settings file that takes the same shape. Restart the client and the five capskip_ tools appear in the agent’s tool list. Nothing else needs wiring, because npx fetches the capskip-mcp package on first run.
From there the agent handles CAPTCHAs itself. It reads the sitekey out of the page, calls capskip_solve_recaptcha or capskip_solve_turnstile with that sitekey and the page URL, and puts the returned token into the response field before submitting the form. This pairs naturally with Playwright MCP or any other browser-automation server: one gives the agent the browser, the other gives it a way through the challenge. If a solve ever fails, capskip_status tells the agent whether the app is running, and because solving is unlimited it can simply try again at no cost.
CAPTCHA MCP server FAQ
What is a CAPTCHA solver MCP server?
It is a Model Context Protocol server that gives an AI agent tools for solving CAPTCHAs. Instead of the agent stalling when a challenge blocks a page, it calls a tool, gets a valid token back, and carries on with the task. CapSkip is an MCP CAPTCHA solver that exposes five such tools and solves the challenge locally on your own machine.
How do I add the CapSkip MCP server to Claude Code?
Add a capskip entry to your MCP config with command npx and args ["-y", "capskip-mcp"], the same block shown above, then restart Claude Code. The CapSkip desktop app must be running, since the MCP server is a client for the local solver rather than a solver itself.
Does it work with Cursor, Windsurf and VS Code?
Yes. capskip-mcp is a standard stdio MCP server, so it works in any MCP client. Claude Code, Claude Desktop, Cursor, VS Code and Windsurf all take the same configuration block; only the location of the config file differs between them.
Which CAPTCHA types can the MCP server solve?
reCAPTCHA v2 (checkbox, invisible and callback), reCAPTCHA v3 and Enterprise, Cloudflare Turnstile, GeeTest v3 slide puzzles, and thousands of image and text CAPTCHA variants. It cannot solve hCaptcha or FunCaptcha/Arkose, and the server tells the agent so rather than letting it waste a call.
Can I use it together with Playwright MCP?
Yes, and that is the usual setup. Playwright MCP drives the browser but has no way past a CAPTCHA; CapSkip supplies the token. Run both servers in the same client and the agent reads the sitekey with one, solves with the other, and submits the form.
Do I need an API key to use the CAPTCHA MCP server?
No. The server connects to the CapSkip app on 127.0.0.1:8080, so there is no account to create and no API key sitting in your MCP client config. An optional CAPSKIP_API_KEY is supported only if you have set one in the app.
How much does the CAPTCHA MCP server cost?
The MCP server itself is free and open source under the MIT licence. Solving needs a CapSkip licence: a $1 trial for 7 days, then $10/month Bronze, $15 Silver or $20 Gold, plus a $99 one-time lifetime licence. There are no per-solve charges, so an agent that retries costs you nothing extra.
What happens if a CAPTCHA takes a long time to solve?
The server sends MCP progress notifications while the solve is running, which keeps the client from timing out on a slow challenge. Each tool also takes a timeout parameter, and if it does expire the agent gets a readable explanation instead of a bare error.
Is the CapSkip MCP server open source?
Yes. It is published on npm as capskip-mcp and the source is on GitHub under the MIT licence, so you can read exactly what it sends and where. Releases are built and published from CI with signed provenance.
Why not just let the model solve the CAPTCHA itself?
Because it does not work. Vision models fail modern challenges regularly, especially when objects straddle several tiles, and reCAPTCHA v3 and Turnstile are scored on behaviour rather than a puzzle at all. A purpose-built solver returns a valid token; a model guessing at tiles does not.
Give your agent a way past CAPTCHAs
Install CapSkip, add one config block to your MCP client, and your agent solves reCAPTCHA, Turnstile, GeeTest and image CAPTCHAs on its own. Unlimited solves, one flat price.
