# Dockerfile for remarkable-mcp
# Builds an optimized image for Docker MCP Toolkit
#
# Key dependencies:
#   remarkable-mcp - MCP server for reMarkable Cloud API
#   rmc - CLI tool to convert .rm files to SVG/PNG (required for remarkable_image)
#   cairosvg - Convert SVG to PNG for image rendering
#
# Rendering pipeline: .rm → rmc → SVG → cairosvg → PNG → OCR

FROM python:3.11-slim AS builder

# Install uv for fast Python package management
RUN pip install --no-cache-dir uv

# Install remarkable-mcp and notebook rendering dependencies
# - rmc: CLI for converting reMarkable .rm files to SVG/PNG
# - cairosvg: SVG to PNG conversion
RUN uv pip install --system remarkable-mcp rmc cairosvg

# --- Final stage ---
