code-atlas

Multi-language code intelligence MCP server — gives Claude Code (and any MCP client) a structured view of your codebase instead of raw text: symbol search, file outlines, AST pattern queries, cross-file references, call/type hierarchies, import graphs, change-impact analysis with affected-test detection, web-framework route maps (Express/NestJS/Fastify/FastAPI/Flask/Django), Mermaid diagrams, precise LSP-backed answers, local-embedding semantic search, and game-engine asset understanding (Godot, Unity, Unreal). 25 languages indexed.

Instead of grepping and reading whole files, the model asks questions like *"map this repo"*, *"outline this file"*, *"who calls parseConfig?"*, *"how does the request handler reach the DB layer?"*, *"what changes whenever this file changes?"* — and gets compact, token-efficient answers backed by a persistent tree-sitter index.

Every answer is budgeted: tools take a max_tokens cap, and a clamped response returns a cursor you can pass back to continue rather than re-asking with a bigger budget.

Status: released (npm @lusiem/code-atlas, MCP registry io.github.lusiem/code-atlas). 25 languages, 32 tools, LSP-exact answers with a structural floor, engine adapters, and an agent-workflow layer (repo_map, context_pack, verify_changes) built for token economy. Validated at 19k files / 6.3M LOC.

How it works

your repo ──scan (gitignore-aware)──> tree-sitter parse ──> SQLite index (symbols, imports,

occurrences, call/type edges, FTS5) │ Claude Code ◄──────────── MCP tools over stdio ────────────────────┘

Persistent index at /.code-atlas/index.db (self-gitignored), incrementally refreshed by content hash.
Live — a gitignore-aware file watcher reindexes saves within a debounce beat and re-resolves only the affected files (--no-watch or "watch": false to disable).
Zero config — point it at a repo root and it works. Optional code-atlas.json for include/exclude tweaks.
Everything local — your code never leaves your machine.

Install & use with Claude Code

claude mcp add code-atlas -- npx -y @lusiem/code-atlas serve

Or from a clone:

git clone https://github.com/lusiem/code-atlas && cd code-atlas

npm install && npm run build claude mcp add code-atlas -- node /path/to/code-atlas/dist/index.js serve

The server indexes the current working directory; pass --root to override.

CLI

node dist/index.js index [--root <path>]              # one-shot index build (debugging / warm-up)

node dist/index.js serve [--root ] [--no-watch] [--no-lsp] [--no-embeddings] [--no-download]

Tools

Full reference with example outputs: docs/tools.md.

Tool	What it answers
`repo_map`	What is this repo and where do I start? Annotated directory tree with import fan-in/fan-out (layering at a glance), entry points, importance-ranked key symbols with the reason each ranks, and the third-party dependency inventory — one budgeted call instead of a grep sweep. `path_prefix`/`depth` to zoom.
`project_overview`	The cheap version: languages, sizes, layout, index freshness.
`search_symbols`	Where is X defined? FTS + fuzzy over names and doc comments, filterable by kind/language/path.
`search_content`	Where does this text appear? String literals, error messages, env vars, config keys, TODOs — and the only tool that sees non-code files (md/json/yaml/toml/sql/Dockerfile/CI). The index proposes candidates, the disk verifies them, so a hit is never stale.
`semantic_search`	"Where is retry backoff implemented?" — natural-language search, hybrid keyword+embedding ranking, fully local.
`get_file_outline`	What's in this file? Hierarchical signatures without reading source — over budget it sheds nesting depth rather than tail lines, so every top-level symbol survives. Pass a directory for a package's public API surface in one call.
`get_symbol_info`	Everything about one symbol (by id, position, or name) incl. docs and source.
`context_pack`	One-call, token-budgeted briefing on a symbol: source, outline, callers/callees, types, route, related tests — instead of six lookups. Sections that don't fit the budget are named.
`batch_symbols`	Up to 50 `#id`s resolved to compact one-liners in a single call.
`ast_query`	Raw tree-sitter S-expression queries — structural search regex can't do.
`find_references`	Who uses this symbol? Exact (LSP) when available, else resolved usages first, name-matches as candidates.
`go_to_definition`	Definition of the identifier at a position. LSP-exact with index fallback.
`call_hierarchy`	Who calls this / what does it call, as a tree. `[lsp 1.00]` edges when a language server is running.
`type_hierarchy`	Supertypes and subtypes over extends/implements edges.
`get_dependencies`	File import graph, both directions (imports / imported-by).
`trace_path`	Shortest call chain between two symbols.
`change_impact`	Blast radius of a change: transitive callers + import reachability, affected test files first. Target a symbol, a file list, or nothing — no args analyzes the uncommitted git diff (hunk-level: only symbols you actually touched seed the traversal). Affected route handlers are tagged `[ROUTE GET /users/:id]`.
`verify_changes`	Post-edit structural check against git HEAD: imports that stopped resolving, removed exports other files still reference, signature changes with live callers. `change_impact` predicts; this confirms.
`tests_for_symbol`	Which tests exercise this symbol? Reverse graph walk to test files, naming the test case; import-chain-only hits reported as a weaker signal.
`find_similar_code`	"Does a helper for this already exist?" — near-duplicate search over the local embedding vectors, with a text-similarity fallback while coverage builds.
`find_dead_code`	Zero-reference symbols after entry-point/route/lifecycle exclusions, confidence-hedged (`possibly dead` when a same-name usage exists anywhere); unused exports listed separately.
`hotspots`	Churn × size risk ranking, answered from the cached commit history.
`change_coupling`	Which files historically change together with this one — the coupling a structural index cannot see (config, fixtures, docs, string-keyed dispatch). Directional confidence, and files with no import edge are flagged.
`symbol_history`	Why does this look like this, and who do I ask? `git log -L` over the symbol's line span: sha, date, author, subject.
`list_routes`	Web-framework routes across the workspace — Express, Fastify, NestJS, FastAPI, Flask, Django, plus file-based routing for Next.js, SvelteKit, Nuxt, and Remix — each linked to its handler symbol.
`find_route`	"Which code serves `GET /api/users/7`?" — matches a concrete URL against indexed route patterns (`:id`, `{id}`, are wildcards) and returns the handler.
`generate_diagram`	Mermaid diagrams of the above graphs: import graph (file or directory level), call graph around a symbol, type hierarchy, call path — paste straight into GitHub markdown or docs.
`get_scene_structure`	Godot scene node tree with attached scripts, instanced sub-scenes, and signal connections (handlers resolved to symbols).
`find_asset_references`	Which scenes/prefabs/Blueprints use this script, asset, or handler? Reverse lookup across Godot res:// paths, Unity GUIDs (via .meta), and Unreal modules + /Game/ Blueprint paths.
`search_reflection`	All `UPROPERTY(Replicated)`, `[SerializeField]`, `@export` vars, signals — engine reflection markers across the workspace.
`index_status` / `reindex`	Index health and manual refresh.

Cross-file answers are LSP-first with a structural floor: when a language server is available (found on PATH or auto-acquired into a per-user cache), references/definitions/hover/call hierarchies are exact and tagged lsp; everywhere else, heuristic import/name resolution answers with a confidence score per edge. Servers: typescript-language-server + pyright (npm), gopls (go install), rust-analyzer + clangd (pinned, SHA-256-verified release binaries), Eclipse JDT LS for Java (needs a Java 21+ runtime — detected via PATH/JAVA_HOME), kotlin-language-server (needs any JRE), and csharp-ls for C# (needs the .NET SDK; installed as a dotnet tool — deliberately not Microsoft's Roslyn LSP, whose license is VS-only). GDScript attaches to the Godot editor's built-in language server (TCP 127.0.0.1:6005, override with CODE_ATLAS_GODOT_LSP_PORT) whenever the editor has the project open — close the editor and answers fall back to structural, reopen it and the next query reattaches. Missing runtimes degrade that language to structural, reported honestly in index_status. A first-time acquisition (download + boot) never blocks a query: tools wait up to 8 s, then answer structurally while the server finishes starting. Disable with --no-lsp; disable auto-download with --no-download.

Semantic search embeds every function/class (signature + doc + body) with a code-tuned local model — jinaai/jina-embeddings-v2-base-code, quantized ONNX — and fuses cosine similarity with BM25 keyword rank. Everything stays on your machine. The ONNX runtime (~220 MB) and model (~150 MB) are not part of this package: they download to the per-user cache the first time you call semantic_search, never at install, and structural tools never wait on them. Until coverage completes, results are keyword-weighted and say so. Embedding a 60k-symbol repo takes ~15 minutes of background time, once; after that only edited symbols re-embed. "embeddings": {"model": "fast"} swaps in a 4× faster general-purpose model; --no-embeddings turns the layer off.

Languages

Indexing today (25): TypeScript, TSX, JavaScript, Python, C, C++, Rust, Go, Java, Kotlin, C#, GDScript, PHP, Ruby, Lua, Solidity, Zig, Nix, Swift, Scala, Dart, Terraform/HCL, Pascal/Delphi, Vue, Svelte.

Vue and Svelte single-file components index the blocks (all of them, included) at their true file line numbers; component imports resolve, so .vue/.svelte dependency graphs work in get_dependencies and change_impact. Terraform maps blocks to symbols (resource "aws_s3_bucket" "logs" is searchable by either label) and resolves local module sources as imports. Languages beyond the LSP-covered core answer structurally with confidence-scored edges — same contract as everywhere else.

Test-file awareness: every indexed file is classified by per-language path conventions (*.test.ts, test_*.py, *_test.go, src/test/, *_spec.rb, foundry .t.sol, …) — this powers change_impact's affected-test reporting. Inline test blocks (Rust #[cfg(test)], Zig test) are not path-classifiable and stay invisible by design.

Game engines: engine assets index alongside code — Godot .tscn/.tres scenes (node trees, script attachments, signal connections, autoloads; res:// resolved per project.godot, monorepos of many projects included), Unity .unity/.prefab/.asset + .meta GUID maps (MonoBehaviour → C# class links, serialized references), and Unreal .uproject/.uplugin/Build.cs module graphs plus indexed reflection macros: UCLASS/USTRUCT/UFUNCTION/UPROPERTY specifiers attach to the symbol they annotate (searchable, shown in get_symbol_info), and dllexport macros (class MYGAME_API AMyActor) no longer break C++ class extraction.

Unreal Blueprints (`.uasset`/`.umap`): binary editor packages are parsed natively (package summary, name/import/export tables, asset-registry tags, and bounded tagged-property r
