About architectos
ArchitectOS is a repository analysis and governance CLI for developers and AI coding agents. It assesses architecture, security, and change impact, then produces refactoring plans without modifying code.
Key features
- 01Repository health and security reviews
- 02Cross-file taint and duplication scans
- 03Dependency cycle detection
- 04Change impact analysis
- 05Actionable refactoring plans
Use cases
- 01Review repository health before a release
- 02Trace risks from a proposed change
- 03Find unused or duplicated code
- 04Prepare migration steps for an AI agent
MCP support
Its MCP server exposes repository review, root-cause analysis, impact calculation, migration planning, symbol resolution, dead-code detection, UI audits, and persistent guardrail tools.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.

From the project READMEArchitectOS
AI-Native Repository Intelligence & Governance Engine
ArchitectOS analyzes your repository, explains its architecture, calculates change impact, and enforces guardrails for AI Agents (Claude Code / Cursor / Codex).
Strict Product Mandate: ArchitectOS never modifies user code directly; it exclusively analyzes, explains, calculates impact, and generates actionable refactoring plans. Code modifications are executed by AI Agents or human developers.

🎯 Engine Precision & Accuracy Features
- 25 CWE-Mapped SAST Engine: High-precision rules covering SQLi, XSS, RCE, ReDoS, Prototype Pollution, NoSQLi, Open Redirect, Unsafe Deserialization, and Weak Cryptography.
- Context-Aware Noise Filter: Automatically suppresses false positives inside test blocks (
describe/it), JSDoc comments, dead conditional branches, and when known sanitizers (DOMPurify,escapeHtml) are detected. - Multi-File Taint Tracking Engine: Traces untrusted user inputs (HTTP
req.body/searchParams) down to dangerous execution sinks across multi-file import graphs. - Code Duplication Scanner: Token-fingerprinted Jaccard similarity engine detecting copy-pasted code blocks across monorepo packages.
- Framework Entrypoint Whitelist: Eliminates false positives for Next.js (
GET,POST,generateMetadata,middleware), Remix, Vitest, and CLI entrypoints. - Tarjan SCC Cycle Detection: Mathematically sound circular dependency cycle detection for complex monorepos.
- Public Scoring Transparency: Fully documented formulas and deduction rules in SCORING.md.
🧪 Real-World Benchmark Verification (v1.2.1 Engine Breakdown)
ArchitectOS is battle-tested and dogfooded across major open-source codebases with transparent sub-metric scoring:
| Repository | Files | Overall | Arch | Sec | Qual | AI | UI | Scan Speed | Top Focus Area |
|---|---|---|---|---|---|---|---|---|---|
excalidraw/excalidraw | 520+ | 88/100 | 92 | 84 | 90 | 94 | 80 | <18ms | Canvas Component Decomposition |
calcom/cal.com | 1,400+ | 84/100 | 80 | 88 | 82 | 90 | 80 | <45ms | Booking Service Layer Isolation |
shadcn/ui | 120+ | 96/100 | 98 | 95 | 96 | 95 | 96 | <8ms | UI Component Primitive Boundaries |
cgseyhan/architectos | 51 | 100/100 | 100 | 100 | 100 | 100 | N/A | <19ms | Native Self-Hosted AST Governance |
Note: Pure CLI / backend repositories (e.g. architectos) omit UI Architecture scoring.
🤖 Native MCP Server Integration

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
