sysml-v2-lsp

sysml-v2-lsp addresses the lack of IDE-quality language support for SysML v2 in VS Code. Its core capabilities include instant syntax error diagnostics, an Outline panel for model structure browsing, hover information for element types, and Ctrl+Click navigation to declarations. The built-in MCP server allows AI assistants like Claude Desktop to access SysML model context through Model Context Protocol. Strengths include lightweight design and the MCP bridge to AI workflows. The project is early-stage (approximately 15 GitHub stars) with limited LSP feature coverage. It suits systems engineers and architects using SysML v2, and is less suitable for teams needing a full graphical SysML toolchain.
