Nothing serious here today

Today is the operative word: we check Captcha MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add captcha-mcp -- npx -y @powforge/captcha-mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "captcha-mcp": {
      "args": [
        "-y",
        "@powforge/captcha-mcp"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.captcha-mcp]
command = "npx"
args = ["-y", "@powforge/captcha-mcp"]
.cursor/mcp.json
{
  "mcpServers": {
    "captcha-mcp": {
      "args": [
        "-y",
        "@powforge/captcha-mcp"
      ],
      "command": "npx"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {
    "captcha-mcp": {
      "args": [
        "-y",
        "@powforge/captcha-mcp"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: CAPTCHA_URL (PowForge captcha backend URL. Defaults to public production endpoint when running via npx; override for self-hosted or local dev.). The author declared them in the registry entry; get the values from the project itself.

Captcha MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Captcha MCP?
Captcha MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @powforge/captcha-mcp was installed 62 times last week.
How do I connect Captcha MCP?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @powforge/captcha-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Captcha MCP?
The npm package @powforge/captcha-mcp was installed 62 times in the last week. Week over week that is +41%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Captcha MCP open source?
Yes — it is published under the MIT licence, written in JavaScript and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
