Add my server

Install 2Captcha MCP in Claude Code

What you need first

  • Claude Code, installed.
  • uv, which gives the uvx command the server starts with.
  • Your own value for YOUR_2CAPTCHA_API_KEY.

Steps

  1. Run this in a terminal, in the project folder. It adds the server for you in that project; put --scope user after claude mcp add to have it in every project.
claude mcp add --env 2Captcha_API_KEY=YOUR_2CAPTCHA_API_KEY --transport stdio twocaptcha-mcp -- uvx twocaptcha-mcp==0.6.1
  1. Replace YOUR_2CAPTCHA_API_KEY with your own value.
  2. Start Claude Code and type /mcp: the server is listed with its state.

Check it worked

Ask Claude Code: List the tools of twocaptcha-mcp.

If it does not start

spawn uvx ENOENT
uv is not on the PATH that Claude Code sees. Install it, or write the full path of uvx in the config.
The server starts, but its tools fail
A YOUR_… placeholder is still in the config, or its value is wrong.
