open acc_diagram.htmlArcLang includes an MCP (Model Context Protocol) server that enables AI assistants like Claude to generate and work with ArcLang models.
The MCP server was used to generate a complete ISO 26262 ASIL-B compliant ACC system:
Generated Model: adaptive_cruise_control_fixed.arc
- ✅ 9 requirements (stakeholder, system, safety)
- ✅ 10 logical components with safety levels
- ✅ 9 component connections
- ✅ Full traceability
Interactive Diagram Output:
Try it yourself:
# Start MCP server
cd mcp-server
python -m arclang_mcp.server
# Use with Claude Desktop or any MCP client
# The AI can now generate ArcLang models!
# Export generated model to HTML
arclang export adaptive_cruise_control_fixed.arc \
--format html \
--output acc_system.html
