App-Kit

npx add-mcp 'https://mcp.app-kit.dev/mcp'

The App-Kit MCP server gives Claude, Cursor and VS Code a page SEO audit, a text check and PDF and image conversion. Ask your agent to review a page, rate an article or turn a PDF into images and it calls the App-Kit engines itself. Free with daily limits: try it without an account, or connect with a free App-Kit account for higher ones.

Try without an account

mcp.app-kit.dev/mcpfree

1. Get a free token

   No email, no sign-up. A token gives you limits of your own, higher than anonymous ones — useful for Claude.ai, where every user reaches us from the same addresses. Get token Before issuing, a Cloudflare Turnstile bot check runs. It loads only after you click the button.

2. Connect your client

   Pick a client, then run the command or paste the config. Your token fills in once you get it. Run in your terminal:

   claude mcp add --transport http app-kit https://mcp.app-kit.dev/mcp \
     --header "Authorization: Bearer <token>"
   

   Claude Code, Cursor and VS Code also work without a token — drop the Authorization header and anonymous limits apply.

Connect with an App-Kit account

This address accepts only App-Kit account sign-in (OAuth). When you add it, your client opens the App-Kit sign-in page in the browser; you sign in or create an account and approve access. No tokens to copy.

mcp.app-kit.dev/mcp/accountaccount

1. Create a free account

   An email and a password are enough. You can also do it from the sign-in page your client opens. The account is used only for the MCP server.

2. Add the server to your client

   Use the account address. On first use the client opens the sign-in page; after you approve access, it connects.

What the server can do

Limits are per tool, per day, and reset at 00:00 UTC, with a shared daily cap per tool on top. Claude.ai requests without a token or account share one hourly pool. Status and quota checks are free. Your agent sees what is left in every response.

What happens to your data

• Server in Germany

  Your AI client connects to mcp.app-kit.dev directly. The server receives only what the agent passes to a tool: a page URL, a text or a file.

• Text and files are not kept

  Text is not kept after the response — only its hash stays in the analysis service log. Result links live 10 minutes; files are deleted within 15 minutes.

• IP only for limits

  Your address is kept as a hash with a daily-rotating key for up to 24 hours. The token is not linked to anyone; we store only its hash.

• Account: email and password hash

  With an account we store your email, a password hash and the sign-up date in Germany. Client tokens are kept as hashes. To delete the account, write to hi@wm2.dev.

FAQ

Model Context Protocol is an open protocol AI agents use to connect external tools. With the App-Kit server connected, you ask your agent in plain words — “check this page’s SEO”, “rate this article’s readability” — and it calls the right tool itself.

A token gives you limits of your own, higher than anonymous ones. Without one, requests from all Claude.ai users reach us from the same Anthropic addresses and share one pool. An App-Kit account gives the highest limits.

A token is the quickest way to try: no email, paste it into your client. An account gives higher limits, and Claude.ai and Claude Code sign you in through the browser, so there is nothing to copy. The account address, mcp.app-kit.dev/mcp/account, accepts only account sign-in; mcp.app-kit.dev/mcp works with or without a token.

Write to hi@wm2.dev from the email address you signed up with. We delete the account together with the tokens issued to your clients.

Get a new one with the “Get token” button above. We cannot show the old one again — we store only its hash. Tokens are valid for 90 days.

If the file has a public URL, the agent passes the link and the server downloads it. For a local file, Claude Code, Cursor and VS Code use create_upload: the server returns a one-time link valid for 10 minutes and the agent uploads the file to it. Small files up to 512 KB can go right in the request. Results come back as links valid for 10 minutes.

The tool returns a clear error to your agent with the time the limit resets. Limits are daily and reset at 00:00 UTC; on top of personal limits there is a shared daily cap per tool.

Any client with remote MCP over Streamable HTTP: Claude Code, Claude.ai (custom connector), Cursor, VS Code with Copilot. Nothing to install — just the server URL. ChatGPT support is coming later.
