App‑Kit tools inside your AI agent
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
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.
Before issuing, a Cloudflare Turnstile bot check runs. It loads only after you click the button.
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.
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.
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 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.
