MCP server for code structure analysis using tree-sitter.
Standalone MCP server for code structure analysis using tree-sitter. OpenSSF silver certified: fewer than 1% of open source projects reach this level.
aptu-coder is a Model Context Protocol server that gives AI agents precise structural context about a codebase: directory trees, symbol definitions, and call graphs, without reading raw files. It supports 18 languages (see Supported Languages) and integrates with any MCP-compatible orchestrator.

| Tool | What it does |
|---|---|
| summary | boolean |
| page_size | integer |
| analyze_directory | Directory tree with LOC, function, and class counts; respects .gitignore |
| analyze_file | Functions, classes, and imports with signatures and line ranges; returns graceful fallback (line count, file head, no AST) for unsupported extensions |
| analyze_module | Lightweight function and import index (~75% smaller than analyze_file); returns graceful fallback (empty index with note) for unsupported extensions |
| analyze_symbol | Call graph for a named symbol across a directory; callers, callees, call depth |
| edit_overwrite | Create or overwrite a file; creates parent directories |
| edit_replace | Replace a unique exact text block or all non-overlapping occurrences (replace_all=true); errors if zero or multiple matches; empty new_text deletes the block; CRLF normalized before matching; returns occurrences_replaced |
| exec_command | Run a shell command; returns stdout, stderr, exit code; output capped and filtered; optional timeout_secs (kill on expiry) and drain_timeout_secs (post-exit drain window); heredoc rejected before spawn (file-write patter |
