Aptu Coder

Built on tree-sitter, this server gives Claude structural insight into codebases across 11 languages without dumping raw files into context. You get directory trees with symbol counts, function signatures with line ranges, call graphs that trace dependencies, and targeted symbol lookups. The analyze_directory, analyze_file, and analyze_symbol tools replace the guess-and-grep pattern with precise structural queries. Benchmarks against Django and OpenFAST codebases show 46-68% token reductions on migration and audit tasks. Supports stdio or HTTP transport, with HTTP recommended for multi-agent setups where goose spawns delegates. Output caps and pagination keep large codebases manageable. Three editing tools and a filtered exec_command round out the kit for actual code changes.
