Beschreibung vom Entwickler (englisches Original)
Code intelligence MCP: symbols, call graphs, change impact + affected tests, routes, search.
Diese drei werden nie zu einer Punktzahl zusammengefasst: Meinungen, Messungen und Beliebtheit sind verschiedene Dinge.

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 registryio.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.

| 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 #ids 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.
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
