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 limits; the token needs no email.
Get a free token
No email, no sign-up. A token raises your limits two to four times, and you need it 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.
What the server can do
Limits are per tool and reset every hour, with a shared daily cap for free access on top. 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.
