Common questions

Is N3mo safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.0.3) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

A structural code intelligence layer that transforms source code into a queryable knowledge graph for search, impact analysis, and AI-powered development.

*Parse once. Query forever. Know exactly what breaks before it does.*

*"Text diffs are the source of all code review anxiety. A developer modifies a core utility, and the reviewer has to spend an hour mentally tracing downstream services to guess if it's safe to merge. N3MO replaces human guesswork with hard math."*

🎯 What is N3MO?

N3MO is a symbol-centric code intelligence layer. Instead of scanning raw text, it parses your source code's ASTs, maps call graphs, and models dependencies in a queryable relational database — deterministically, with zero LLM calls at index time.

For engineering leaders and teams, N3MO acts as a structural insurance policy for your codebases.

💡 Why N3MO?

🛡️ Eliminate Regression Risks — Utility functions are rarely refactored because developers fear unknown side effects. N3MO maps the transitive blast radius of any symbol to arbitrary depth, showing you exactly what will break before you make the edit. [Automate this in your CI/CD →](https://n3mo.shop)
🏎️ Rapid Developer Onboarding — Instead of senior engineers spending hours explaining codebase flow to new hires, developers run one command to visualize complex call chains and parent-child dependencies interactively.
🤖 AI-Agent Ready Infrastructure — Modern LLM agents (Cursor, Claude Desktop) are limited by context windows and text search. N3MO's native MCP server lets agents query the actual code graph, enabling fast, hallucination-free refactoring.
⚡ No Embeddings, No Drift — N3MO is pure static analysis: Tree-sitter AST parsing into PostgreSQL. There's no vector index to keep in sync, no embedding cost per repo, and no semantic-similarity guesswork — every edge in the graph is an exact, verifiable relationship.

📊 How N3MO Compares

Capability	Grep / Text Search	IDE "Find References"	N3MO Code Graph
Analysis Basis	Substring matching	AST-based, direct refs only	Relational knowledge graph
Transitive Traversal	❌ None	❌ Manual, one level at a time	⚡ Instant to arbitrary depth
Blast Radius Mapping	❌ None	❌ Flat search-result list	🎨 Interactive visual orbit map
CI/CD Integration	❌ None	❌ Bound to IDE runtime	⚙️ Dockerized CLI + CTE queries
AI Agent Integration	❌ Injected file chunks	⚠️ Manual context copy	🤖 Native MCP server
Language Coverage	✅ Any text file	⚠️ Language-specific plugins	✅ 27 Tree-sitter grammars
Indexing Method	N/A	N/A	✅ Deterministic AST parse — no embeddings, no LLM calls

🛠️ The Core Problem N3MO Solves

❌ Without N3MO

Developer: "Where does 'login' appear?" Tool: grep -r "login" . Result: 647 matches across 89 files ...now what?

✅ With N3MO

Developer: "What breaks if I change login?" Tool: n3mo impact "login" Result: 3 direct callers → 5 ripple effects Full blast radius in < 50ms

N3MO doesn't find text — it understands structure. It traces the actual call graph, not string matches.

✨ Core Capabilities

Ingestion & Parsing

Multi-language support — 27 Tree-sitter grammars supported (dynamically loaded); actively benchmarked on 10 major languages including Python, JS/TS, Go, Java, and C/C++
Parallel AST ingestion — ProcessPoolExecutor distributes CPU-bound parsing across all available cores
Incremental re-indexing — SHA-256 file hashing skips unchanged files automatically
Idempotent operations — re-indexing updates existing data without duplication
Smart exclusions — case-insensitive directory filters and camelCase-aware filename checks prevent false positives (e.g. allows contest.py while skipping test_*.py)

Analysis & Querying

Symbol extraction — functions, classes, methods with full file path + line context
Hierarchical modeling — parent-child relationships (Module → Class → Method)
Call graph construction — who calls whom, resolved at ingestion time
Scope-aware resolution — class scope > local file > imports > qualified dot paths > global
Blast radius analysis — recursive CTE traversal to arbitrary depth with cycle guards

Performance

Connection pooling — ThreadedConnectionPool eliminates per-symbol DB round trips
Batch inserts — symbols, imports, and calls batched per file in single transactions
Optimized queries — SPLIT_PART fix delivered a 2× speedup on call resolution

Visualization & Integration

Interactive graph — vis.js orbit map with click-to-inspect nodes, sidebar, and depth slider
Dark mode — toggleable canvas dark mode with real-time node/edge updates, persisted in localStorage
Premium styling — sleek interactive dashboard landing page UI and graph visualizer styled with Bricolage Grotesque, Inter, and JetBrains Mono typography
[SKILL.md](SKILL.md) profile — system instructions to configure Claude as an impact-aware coding agent
Native MCP server — first-class integration with Cursor, Claude Desktop, and Windsurf
Git hooks — automatic re-indexing on every commit
CI pipeline — GitHub Actions with linting (ruff), type checking (mypy), and pytest

🌐 Supported Languages
