TSG Indexer

What is TSG Indexer?

TSG Indexer is a Rust library that uses Tree-sitter Stack Graphs to analyze code repositories and build graph representations of code structure. It captures relationships between definitions and references across files, enabling code navigation and analysis for MCP servers and other tools.

How to use TSG Indexer?

Add it as a dependency in your Rust project's Cargo.toml with optional cli and lsp features. Use the IndexerConfig and run_indexer API to index a file or directory. If built with CLI support, run tsg_indexer_cli with a path and optional flags for output format and file.

• Supports 20+ programming languages including Rust, Python, JavaScript, and more
• Recursive directory traversal for comprehensive codebase analysis
• Output formats: JSON and DOT graph
• Optional CLI and LSP support via feature flags
• Ability to generate TSG files for unsupported languages

Use cases of TSG Indexer

• Integrate code indexing and navigation into an MCP server
• Build graph representations of code structure for analysis tools
• Find definitions and references across files in a multi-language project
