Ix
Understand any codebase instantly. System intelligence for codebases, built for humans and AI.
Ix is a codebase intelligence system that parses repositories into a persistent graph of symbols, calls, imports, and relationships, exposing that structure to AI coding agents through an MCP server. It replaces inefficient file-grepping with structured queries, enabling agents to answer architecture questions by navigating a pre-built graph rather than re-deriving context from raw source files each session. The tool ships a CLI for local graph operations, an MCP server for agent integration, and a visual explorer called Compass.
Key Features
Use Cases
- 01Enable AI coding agents to understand codebase architecture without re-reading files every session
- 02Query impact radius before refactoring to see what breaks if a function signature changes
- 03Trace execution flows through multi-file call chains without grepping
- 04Find load-bearing code by ranking symbols by dependents or callers
- 05Generate architecture summaries from the persistent graph rather than scanning source repeatedly
- 06Detect structural code smells and anti-patterns across the entire repository

Ix — FAQ
What is Ix and how does it help AI agents?+
Ix is a codebase intelligence tool that parses your repository into a persistent graph of symbols, calls, and imports. AI agents query this graph through an MCP server to answer architecture questions without pasting entire files into prompts, cutting token use by 30–99.7%.
How do I install Ix and connect it to my AI client?+
Run 'curl -fsSL https://ix-infra.com/install.sh | sh' on macOS/Linux or the PowerShell equivalent on Windows. Then run 'ix map .' to build the graph and 'ix mcp install' to auto-register the MCP server with detected clients like Claude Code, Codex, and Cursor.
Which AI clients and editors work with Ix?+
Ix supports any MCP-capable client and auto-registers with Claude Code, Codex, Cursor, VS Code, Gemini CLI, OpenClaw, and OpenCode. You can also manually add the MCP server or install native plugins for each client.
What are the prerequisites to run Ix?+
You need Node.js 22+, Git, ripgrep, and Docker with Docker Compose. The installer checks for these dependencies and installs missing ones automatically. The backend (ArangoDB plus memory layer) runs locally in Docker.
Is Ix free to use?+
Yes, Ix is licensed under Apache 2.0 and runs entirely on your local machine. The backend Docker image and all clients are open source.
Which programming languages does Ix support?+
Ix extracts symbols, calls, and imports from 27 languages including JavaScript, TypeScript, Python, Java, C, C++, C#, Go, Ruby, Rust, PHP, Kotlin, Swift, Scala, Bash, PowerShell, and more. It also recognizes config formats like YAML, JSON, and TOML.
How do I install Ix?+
Open the source repository on GitHub and follow its README. Ix is a mcp server — MCP Agents Market links you directly to the official repo.
Is Ix free?+
Ix is an open-source project hosted on GitHub. Check the repository for its license and any usage requirements.
