V.I.S.O.R.

Your AI coding assistant wastes time reading the wrong files. V.I.S.O.R. fixes that.

Visual Intelligence System for Orchestrated Reasoning

V.I.S.O.R. is a smart helper for your AI coding assistant. It reads your code, understands how files are connected, and gives your AI exactly the right context — so it spends less time searching and more time solving.

It works with Antigravity, VS Code, Cursor, Claude Code, and Windsurf.

💬 What Can You Do With It?

Just talk to your AI agent like normal. V.I.S.O.R. works behind the scenes to find the right code automatically.

Find a bug

"Find the code related to the login crash"

Without V.I.S.O.R., your AI reads 20+ files blindly. With V.I.S.O.R., it gets the 3–5 most relevant files instantly.

Understand your code

"Explain how authentication works in this project"

V.I.S.O.R. traces the full auth flow across files — showing your AI exactly which functions call which, and in what order.

Refactor safely

"What files would break if I change the database client?"

V.I.S.O.R. runs an impact analysis and shows every file that depends on the one you're changing.

Check for stale context

"Are the files you read earlier still up to date?"

V.I.S.O.R. checks file hashes and warns your AI if something changed since it last looked.

🚀 Install (2 minutes)

Step 1: The One-Command Install

You no longer need to manually copy and paste JSON configuration files. V.I.S.O.R. includes an interactive setup wizard that automatically configures your IDE.

# This will auto-detect Cursor, VS Code, or Antigravity and set up the MCP connection
uvx visor-mcp init

Note: Claude Code handles installation natively via claude mcp add visor -- uvx visor-mcp.

Prefer manual installation? Click here for raw configs

Cursor (~/.cursor/mcp.json):

{
  "mcpServers": {
    "visor": {
      "command": "uvx",
      "args": ["visor-mcp"]
    }
  }
}

VS Code / Antigravity (.vscode/mcp.json):

{
  "servers": {
    "visor": {
      "command": "uvx",
      "args": ["visor-mcp"]
    }
  }
}

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "visor": {
      "command": "uvx",
      "args": ["visor-mcp"]
    }
  }
}

Prerequisite: You need uv installed. uvx (included with uv) handles virtual environments and dependencies automatically — no manual setup needed.

Step 2 (Optional): Install the 3D HUD Extension

Search for "V.I.S.O.R. HUD" in your editor's extension panel, or install from Open VSX. This gives you a live 3D visualization of your codebase graph right in the sidebar.

🤔 The Proof: Why You Need V.I.S.O.R.

Every time your AI agent searches for context natively, it relies on brute-force text search (grep or ripgrep). This wastes tokens, misses dependencies, and hallucinates context.

Here is what happens when you ask an AI to "refactor the database client":

AI Without V.I.S.O.R. ❌	AI With V.I.S.O.R. 🎯
Searches db_client and reads 24 files blindly.	Instantly retrieves the db_client.py AST node.
Uses 14,500 tokens filling the context window.	Uses 1,800 tokens (an 87% reduction).
Misses src/auth.py because the word "database" wasn't explicitly mentioned in the file.	Identifies src/auth.py because it detects a hard dependency graph link.
Result: A broken refactor because it didn't update the authentication service that depended on the database.	Result: A perfect refactor because it had complete, surgically precise context.

✨ Key Features

🧠 Smart Context Engine

The heart of V.I.S.O.R. When your AI asks "find code related to X", it doesn't just search by text — it thinks:

• Understands your question — Detects if you're fixing a bug, exploring, or refactoring, and adjusts accordingly
• Scores code 5 different ways — Combines meaning similarity, name matching, file proximity, code connections, and how recently the file was changed
• Explains its choices — Every code snippet includes a plain-English reason for why it was picked
• Saves tokens — Shows you exactly how many tokens it saved vs. a naive approach

⚡ Built-in Skills

Pre-built strategies that change how V.I.S.O.R. finds code. Think of them as "modes":

Skill	What it does
bug-fixer	Focuses on recently changed files and dependency chains
architecture-explainer	Casts a wide net to help explain how things connect
refactor-assistant	Traces all dependencies so you know what might break
performance-optimizer	Finds hotspots by prioritizing recently modified code

You can also create your own custom skills.

🔍 Code Understanding

V.I.S.O.R. reads your code structure (classes, functions, imports) in 9 languages:

Language	File Types
Python	.py
TypeScript	.ts, .tsx
JavaScript	.js, .jsx
Go	.go
Rust	.rs
Java	.java
C	.c, .h
C++	.cpp, .cc, .cxx, .hpp

Want more? Adding a new language is ~15 lines of code. See CONTRIBUTING.md.

📊 3D HUD (VS Code / Antigravity)

A real-time interactive graph of your codebase — right in your editor sidebar. Shows:

• Your code as connected nodes you can explore
• Live stats: how many tokens your AI is using, how many files are indexed
• Drift alerts when files change under your AI

⚠️ Drift Detection

Knows when your AI is looking at outdated code. Compares file hashes and warns before your AI makes decisions on stale information.

📦 Example: Finding a Bug

$ visor fix "authentication crash"

============================================================
  V.I.S.O.R. Context Intelligence Engine
============================================================
  Query:  authentication crash
  Intent: BUG_FIX
  Skill:  bug-fixer
────────────────────────────────────────────────────────────
  Tokens without V.I.S.O.R.: 11,400
  Tokens with V.I.S.O.R.:    2,180
  Reduction:                  80.9%
────────────────────────────────────────────────────────────
  Selected 4 nodes (truncated=False):

  [2.85]  src/auth/jwt.py:verify_token
          → Matched query token in symbol name
          → Co-located in same file as top semantic hit
          → Recently modified file (boosted)

  [2.12]  src/auth/middleware.py:auth_guard
          → Reachable via dependency chain
          → Semantic similarity (score: 0.375)

============================================================

What happened: Instead of your AI reading every file in the project, V.I.S.O.R. found the 4 most relevant functions and saved 80% of the tokens.
