# Builds the Node.js entry (src/index.js) of the MCP App server.

# Build from the REPOSITORY ROOT, not from this directory: at startup the

# server reads the shared references and the shape index from the sibling

# ../shared and ../shape-search directories.

# docker build -f mcp-app-server/Dockerfile -t drawio-mcp-app .

# docker run --rm -p 3001:3001 drawio-mcp-app

# The endpoint is then http://localhost:3001/mcp (PORT overrides the port).

# Published to Docker Hub as jgraph/drawio-mcp (linux/amd64 + linux/arm64) by

# .github/workflows/publish-app-server-image.yml.
