# John's Essentials

> Deterministic file-processing tools — PDF, image, media, document, conversion and analysis — run as a website, a REST API, or natively inside AI assistants over MCP. Operated by John's Essentials, incorporated in Wyoming, USA; files are processed on servers in Germany (EU), deleted on a published retention schedule, never used to train models, never shared.

## What this is

Every tool gives the same output for the same input, every time: no model in the loop, no hallucinated results. The same catalogue is reachable three ways.

- **Website:** https://johnsessentials.com — upload a file, get the result.
- **AI assistants (MCP):** https://johnsessentials.com/docs/mcp — connect Claude, ChatGPT, Cursor, Gemini or n8n in one click via OAuth. Server identity: https://api.johnsessentials.com/mcp/health
- **Developers (REST):** https://johnsessentials.com/api — API keys, OpenAPI spec, SDKs. Machine-readable reference: https://api.johnsessentials.com/llms-full.txt
