What can you do with this server?

The CodeAtlas MCP Server exposes codebase analysis data to AI assistants, enabling them to query project structure, dependencies, and AI-generated insights. * List Projects (list_projects): Discover all CodeAtlas-analyzed projects under your home directory, returning their names, paths, and last analysis timestamps. * Get Project Structure (get_project_structure): Retrieve all modules, classes, functions, and variables in a project, with optional filtering by entity type and result limits. * Get Dependencies (get_dependencies): Explore import, call, and containment relationships between entities, with filtering by source, target, and relationship type. * Get Insights (get_insights): Access AI-generated code quality insights including refactoring suggestions, security issues, and maintainability analysis. * Search Entities (search_entities): Fuzzy search for functions, classes, modules, or variables by name across a project, with optional type filtering. * Get File Entities (get_file_entities): Retrieve all classes, functions, and variables defined within a specific file using partial path matching. Compatible with major AI tools including Gemini, Claude, Cursor, Windsurf, and VS Code Copilot. Supports both npx execution and global installation.

How do I use CodeAtlas MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@CodeAtlas MCP Server show the module structure and dependencies for the current project" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

🗺️ CodeAtlas MCP Server

Give your AI assistant deep understanding of any codebase

npm License Node

A standalone MCP server that exposes code analysis data to Gemini, Claude, Cursor, Windsurf, VS Code Copilot — with persistent AI memory between conversations.

✨ What Does It Do?

Your Code → CodeAtlas Analyze → MCP Server → AI Understands Everything
                                     │
                              10 powerful tools:
                              • Search functions & classes
                              • Trace feature flows
                              • Generate architecture diagrams
                              • Persistent memory across conversations

Before CodeAtlas: AI greps blindly, forgets your project every conversation. After CodeAtlas: AI instantly knows your architecture, dependencies, and remembers context.

🚀 Setup (1 minute)

1. Analyze your project

Install the CodeAtlas extension, then:

Ctrl+Shift+P → CodeAtlas: Analyze Project

2. Add MCP config to your AI

{
  "mcpServers": {
    "codeatlas": {
      "command": "npx",
      "args": ["-y", "@giauphan/codeatlas-mcp"]
    }
  }
}

{
  "mcpServers": {
    "codeatlas": {
      "command": "npx",
      "args": ["-y", "@giauphan/codeatlas-mcp"]
    }
  }
}

{
  "mcp": {
    "servers": {
      "codeatlas": {
        "command": "npx",
        "args": ["-y", "@giauphan/codeatlas-mcp"]
      }
    }
  }
}

{
  "mcpServers": {
    "codeatlas": {
      "command": "npx",
      "args": ["-y", "@giauphan/codeatlas-mcp"]
    }
  }
}

claude mcp add codeatlas -- npx -y @giauphan/codeatlas-mcp

{
  "mcpServers": {
    "codeatlas": {
      "command": "npx",
      "args": ["-y", "@giauphan/codeatlas-mcp"]
    }
  }
}

Done! Your AI can now use all 10 CodeAtlas tools.

🛠️ 10 MCP Tools

`list_projects`	List all analyzed projects	"What projects do I have?"
`get_project_structure`	Get modules, classes, functions	"Show me all classes"
`get_dependencies`	Import/call/containment relationships	"What does UserService depend on?"
`get_insights`	Code quality & security analysis	"Any security issues?"
`search_entities`	Fuzzy search entities by name	"Find the login function"
`get_file_entities`	All entities in a specific file	"What's in auth.ts?"

🧠 AI Memory — Persistent Context

AI assistants forget everything between conversations. CodeAtlas fixes this:

Conversation 1 → AI analyzes code → sync_system_memory
                                          │
                                   .agents/memory/
                                   ├── system-map.md       ← Architecture diagram
                                   ├── modules.json        ← All entities
                                   ├── conventions.md      ← Code patterns
                                   ├── business-rules.json ← Domain logic
                                   ├── feature-flows.json  ← Feature traces
                                   └── change-log.json     ← Change history
                                          │
Conversation 2 → AI reads memory → full context restored instantly ✨

Auto-Generated IDE Rules

When you run Analyze Project, CodeAtlas auto-creates rule files for your AI IDE:

Generated File	For
`.agents/rules/codeatlas-mcp.md`	All AI assistants
`.cursor/rules/codeatlas.mdc`	Cursor
`CLAUDE.md`	Claude Code
`.windsurfrules`	Windsurf

These tell your AI to:

Read .agents/memory/ at the start of every conversation
Use MCP tools before making changes
Call sync_system_memory after completing changes

🌍 Supported Languages

Language	Features
TypeScript / JavaScript	Full AST: imports, classes, functions, variables, calls, implements
Python	Classes, functions, variables, imports, calls
PHP	Classes, interfaces, traits, enums, functions, properties
