MCP BSL LSP Bridge

What it does

Connects AI agents (like Cursor and Claude Code) to the BSL Language Server, providing high-fidelity access to 1C:Enterprise and OneScript codebases. It enables deterministic operations such as symbol navigation and refactoring, significantly reducing token consumption compared to grep-based searches.

Tools

• project_analysis: Universal search for symbols, files, and text.
• symbol_explore: Detailed search providing code and documentation for specific symbols.
• definition: Direct navigation to a symbol's definition.
• hover: Retrieves documentation and function signatures.
• get_range_content: Extracts specific code fragments via coordinates.
• call_hierarchy: Maps immediate caller/callee relationships.
• call_graph: Generates a complete call graph for deep architectural analysis.
• document_diagnostics: Performs syntax checks and style audits.
• code_actions: Provides automated quick-fixes for detected errors.
• rename: Performs project-wide symbol renaming.
• lsp_status: Monitors LSP connection and indexing progress.
