A self-hosted print studio: images at exact physical sizes, sheet layout with crop marks, tiling, 1:1 PDF. Everything else — image generation, delivery, share links, mail, Telegram — is an optional module that is off by default. This is the neutral public twin of a private tool. Compared to that original: - optional modules behind KLARBILD_MODULES; the default install is print-only - English interface with German as a full second language (1,038 strings); the English sentence is the translation key - no built-in accounts — first boot creates one admin from ADMIN_USERNAME / ADMIN_PASSWORD, or generates a password and logs it once - delivery and backup targets are generic SFTP/FTPS endpoints, off by default - English routes, English identifiers, English comments throughout - two compose files: print-only by default, everything in the full one - AGPL-3.0, CI (build, tests, type check, secret scan), CONTRIBUTING, SECURITY 124 tests green, type check clean, verified end to end against a live instance.

// Klarbild MCP server — lets an AI assistant (e.g. Claude) hand local images, or
|
||||
// images obtained some other way (iMessage, a given folder, …), over to Klarbild
|

// for processing. The assistant fetches the image files; this server uploads
|
||||
// them and creates a job.

//
|

// Setup:
|

// npm i @modelcontextprotocol/sdk

// KLARBILD_URL=https://klarbild.example.com \
|

// KLARBILD_TOKEN=klb_xxx node mcp/klarbild-mcp.mjs
