# Dockerfile for Wolfram MCP Server
# https://github.com/WolframResearch/AgentTools
#
# This image provides a containerized MCP server that enables LLMs to access
# Wolfram Language computation capabilities via the Model Context Protocol.
#
# Usage:
#   docker run -i --rm \
#     -e WOLFRAMSCRIPT_ENTITLEMENTID=your-entitlement-id \
#     -e MCP_SERVER_NAME=Wolfram \
#     ghcr.io/wolframresearch/mcpserver:latest
#
# For node-locked licensing (free but requires persistent storage):
#   docker run -i --rm \
#     -v ./Licensing:/home/wolframengine/.WolframEngine/Licensing \
#     -e MCP_SERVER_NAME=Wolfram \
#     ghcr.io/wolframresearch/mcpserver:latest
