🎯 The Paradigm Shift

Standard AI coding agents waste tokens and computation time looping through simple directory scans or grep commands. CodexMemory replaces primitive tool-thrashing with a single, atomic, sub-50ms vector payload.

Here is why CodexMemory's architecture offers unparalleled code retrieval performance:

⚡ 1. The Synaptic Grid (Zero-String Memory Mapping)

Most "Code RAG" tools dump your entire repository into a massive Python dictionary, bloating your RAM to 4GB+ and begging for a Garbage Collection stutter. We engineered that out.

CodexMemory uses a C-struct binary pointer system (SynapticGrid) backed by OS-level memory mapping (mmap).

• We don't store your strings in RAM. We store 32-byte binary pointers.
• When the LLM requests a code chunk, our Thread-Safe LRU Cache slices the exact bytes straight off your SSD using mmap, completely bypassing Python's memory bloat.
• The Result: You can index a 500,000-line project and CodexMemory will idle at ~32MB of RAM.

🧬 2. Codex Holographic Slicing (Mathematical Context)

Chunking code by arbitrary token counts (e.g., 512 tokens) is a catastrophic failure that slices functions in half and blinds the LLM to variables.

CodexMemory uses Tree-Sitter to surgically parse the Abstract Syntax Tree (AST) for 40+ languages. But we didn't stop at AST boundaries. We built Holographic Dependency Injection.

• If Function A calls Function B from another file, CodexMemory mathematically maps the Call Graph.
• Before vectorizing Function A, it seamlessly injects the exact signature and docstring of Function B directly into the chunk header.
• The Result: The LLM receives a "Holographic Splice"—a single chunk containing the exact logic and its cross-file dependencies. Zero hallucination. 100% Zero-Shot execution.

🔌 3. The Nervous System (Live Asynchronous I/O)

Codebases are living organisms; static indexes are dead on arrival. CodexMemory runs a highly optimized background Watchdog daemon that listens to your OS. When you hit CTRL+S:

1. It debounces the event queue to handle mass git-branch switches.
2. It surgically recalculates the AST, the BM25 tokens, and the MiniLM FAISS vectors in RAM only.
3. It safely drops a synchronized flush_to_disk atomic batch commit, completely protecting your SSD from I/O thrashing.

• The Result: Your AI agent's memory is perfectly synced to your live keystrokes, with zero IDE freeze and zero JSON-RPC pipe contamination.

🎯 4. Sub-Lexical Reciprocal Rank Fusion (RRF)

Vector embeddings alone are terrible at finding exact UUIDs or specific variables. We implemented the exact retrieval math used by enterprise search engines.

• Sub-Lexical BM25: Our custom sparse index natively splits calculateTradeMargin into calculate, trade, and margin, guaranteeing exact keyword hits.
• MiniLM FAISS: Our dense index captures the semantic intent.
• The Fusion: The engine fuses the Dense and Sparse ranks together at the exact chunk level using RRF.

⚡ How It Works (The 100x Architecture)

1. Automatic Project Detection & Indexing

When your IDE (like Cursor or Antigravity) boots up, CodexMemory wakes up in the background:

1. Smart Root Detection: It walks upward through your file system to detect the true project root by looking for markers like .git, package.json, or requirements.txt.
2. Auto-Build (New Projects): If it has never seen the project before, it silently scans every file, extracts the AST (Abstract Syntax Tree), chunks the code semantically, and generates AI vectors using MiniLM. It saves this as a mathematically indexed FAISS database inside a hidden .codexmemory folder.
3. Instant Load (Existing Projects): If the .codexmemory folder already exists, it completely skips the build and loads the AI matrix directly into RAM instantly.

2. The Live "Nervous System" (Watchdog)

Once loaded, CodexMemory starts a background daemon:

• Edit a file: It detects the save, waits 2 seconds, and surgically updates only that specific file's vectors in the FAISS index.
• Create/Delete a file: It instantly indexes new files or removes deleted vectors to prevent stale AI hallucinations.
• Result: Your AI assistant is always perfectly synchronized with your code in real-time.

🚀 Quickstart & Installation

By installing CodexMemory, you inject a highly optimized, AST-aware nervous system into your MCP-compatible IDE or custom agent framework. Designed for instant semantic retrieval, this replaces primitive looping with atomic context injections.

⚡ Step 0: The Global Universal Engine

Before connecting your clients, you must install the CodexMemory engine globally. We strictly recommend using uv for blazing-fast dependency resolution.

# 1. Create an isolated global environment
uv venv ~/.codexmemory_engine

# 2. Install the heavy ML dependencies and the server
uv pip install codexmemory --python ~/.codexmemory_engine

🪄 Step 1: The Antigravity Auto-Installer (Recommended for Antigravity Users)

If you are using Google Antigravity IDE, CodexMemory comes with an elite, autonomous installer that mathematically merges the MCP server configuration into your raw JSON files without erasing your existing plugins. (Note: This installer is strictly designed for Google Antigravity. For all other IDEs, use the manual wiring guides below).

Simply run the auto-installer script from your global environment:

Windows / Linux / macOS (Global Binary):

~/.codexmemory_engine/bin/codexmemory-install

(On Windows, use ~\.codexmemory_engine\Scripts\codexmemory-install.exe)

It will automatically locate ~/.gemini/antigravity/mcp_config.json and inject the payload. Once completed, simply restart your IDE and CodexMemory will be live.

🔌 Manual Configuration Overrides (2026 Updated)

If you prefer to manually wire the architecture into your system or air-gapped environment, use the exact payload formats and fully verified 2026 integration steps below.

1. Cursor (The Local Heavyweight)

Cursor's native agent is powerful, but it inherently suffers from conversational context drag when searching large codebases. CodexMemory bypasses their standard file-passing logic, feeding the agent mathematically precise "Holographic Splices" via standard input/output (stdio).

The 60-Second Hookup:

1. Open Cursor and press Ctrl/Cmd + Shift + J to open Cursor Settings.
2. Navigate to the Features -> MCP Servers tab in the sidebar (or Tools & MCP depending on your exact version).
3. Click + Add New MCP Server.
4. Enter the following exact configuration:
   • Name: codexmemory
   • Type: command (or stdio on legacy builds)
   • Command: ~/.codexmemory_engine/bin/python (On Windows: %USERPROFILE%\.codexmemory_engine\Scripts\python.exe)
   • Args: ["-m", "codexmemory.mcp_server"]
5. Hit Add / Save. Wait for the green status indicator to confirm the connection.

The Manipulation: Do not leave all 40 of your random, experimental MCP tools enabled. Cursor's LLM routing deteriorates when overwhelmed with tool descriptions. Turn off the garbage, leave CodexMemory on, and watch your zero-shot success rate skyrocket.

🏄‍♀️ 2. Windsurf IDE (Codeium)

Windsurf leverages "Cascade" to orchestrate complex RAG queries. To plug CodexMemory securely into Windsurf's 2026 architecture:

1. Locate your Windsurf MCP configuration JSON:

   • macOS/Linux: ~/.codeium/windsurf/mcp_config.json
   • Windows: %USERPROFILE%\.codeium\windsurf\mcp_config.json (Alternatively, open "Windsurf Settings" -> Cascade -> Click the custom tool 'hammer' icon to view the raw configs).

2. Inject the MCP payload into the 'mcpServers' block. Ensure the absolute path to your Python virtual environment is correct:

{
  "mcpServers": {
    "codexmemory": {
      "command": "/Users/YOUR_USER/.codexmemory_engine/bin/python",
      "args": ["-m", "codexmemory.mcp_server"],
      "env": {
        "PYTHONUTF8": "1"
      }
    }
  }
}

3. Restart Windsurf. Cascade will now natively invoke resonance_search.

🦊 3. Roo Code (VS Code Extension)

Roo Code (formerly Roo Cline) operates as a powerful VS Code extension utilizing the Model Context Protocol.

1. Locate the VS Code Global Storage path for the Roo Code extension settings:

   • Mac/Linux: ~/Library/Application Support/Code/User/globalStorage/rooveterinaryinc.roo-cline/settings/cline_mcp_settings.json
   • Windows: %APPDATA%\Code\User\globalStorage\rooveterinaryinc.roo-cline\settings\cline_mcp_settings.json (Or press Ctrl/Cmd+Shift+P, type Roo Code: Open MCP Settings).

2. Modify cline_mcp_settings.json to include the standard payload:

{
  "mcpServers": {
    "codexmemory": {
      "command": "/Users/YOUR_USER/.codexmemory_engine/bin/python",
      "args": ["-m", "codexmemory.mcp_server"],
      "env": {
        "PYTHONUTF8": "1"
      }
    }
  }
}

---

🚀 4. Cline (VS Code Extension)

Cline (the original Claude Dev extension) shares a similar architecture to Roo Code, but uses a different global storage directory.

1. Locate the configuration file:

   • Mac/Linux: ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json
   • Windows: %APPDATA%\Code\User\globalStorage\saoudrizwan.claude-dev\settings\cline_mcp_settings.json (Or press Ctrl/Cmd+Shift+P, type Cline: Open MCP Settings).

2. Inject the identical standard payload:

{
  "mcpServers": {
    "codexmemory": {
      "command": "/Users/YOUR_USER/.codexmemory_engine/bin/python",
      "args": ["-m", "codexmemory.mcp_server"],
      "env": {
        "PYTHONUTF8": "1"
      }
    }
  }
}

🧠 5. Claude Desktop (The Anthropic Standard)

Claude Desktop relies on standard local STDIO connections to extend its capabilities with custom tools. By routing Claude through CodexMemory, you give it instantaneous, cross-file architectural vision without blowing past its context limits.

The Hardwired Integration:

1. Open your Claude Desktop configuration file. If the file or folder doesn't exist, create it:

   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Inject the following JSON payload into your mcpServers object:

{
  "mcpServers": {
    "codexmemory": {
      "command": "/Users/YOUR_USER/.codexmemory_engine/bin/python",
      "args": [
        "-m",
        "codexmemory.mcp_server"
      ],
      "env": {
        "CODEX_PROJECT_ROOT": "/path/to/your/current/monorepo",
        "PYTHONUTF8": "1"
      }
    }
  }
}

3. Save the file and completely restart Claude Desktop (Command+Q / Ctrl+Q to exit fully, do not just close the window). You will now see CodexMemory listed as an active connection with the "plug" icon.

---

⚡ 6. Zed IDE (The High-Performance Native Editor)

Zed uses a centralized settings.json file rather than a dedicated MCP file, and profoundly, it uses the context_servers key instead of the standard mcpServers.

1. Open your Zed configuration file (Command/Ctrl + Shift + P -> zed: open settings):

   • macOS/Linux: ~/.config/zed/settings.json
   • Windows: %APPDATA%\Zed\settings.json

2. Inject the CodexMemory hook into the root of the JSON file:

{
  "context_servers": {
    "codexmemory": {
      "command": "/Users/YOUR_USER/.codexmemory_engine/bin/python",
      "args": [
        "-m",
        "codexmemory.mcp_server"
      ],
      "env": {
        "CODEX_PROJECT_ROOT": "/path/to/your/current/monorepo",
        "PYTHONUTF8": "1"
      }
    }
  }
}

3. Save the file. Zed hot-reloads its settings immediately; the MCP server will spin up in the background.

🌌 7. Google Antigravity (The Agentic Mission Control)

Google Antigravity is an agent-first IDE designed for orchestrating asynchronous swarms of agents across multiple workspaces. Standard retrieval methods choke when five agents hit the disk simultaneously. CodexMemory’s thread-safe LRU cache handles this natively, feeding your entire Antigravity swarm from a single RAM state.

The Mission Control Override:

1. Launch Antigravity and open the Agent Manager (your Mission Control dashboard).
2. Click the ... dropdown menu at the top of the Agent Manager panel to open the built-in MCP Store.
3. Click on Manage MCP Servers. From here, click View raw config to open mcp_config.json (typically stored at ~/.gemini/antigravity/mcp_config.json).
4. Modify the mcp_config.json by adding your local CodexMemory server definition:

{
  "mcpServers": {
    "codexmemory-search": {
      "command": "/Users/YOUR_USER/.codexmemory_engine/bin/python",
      "args": ["-m", "codexmemory.mcp_server"],
      "env": {
        "PYTHONUTF8": "1"
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}

5. Ensure your agent permission mode is set correctly—if you are letting Antigravity auto-execute tasks, CodexMemory's perfectly bounded AST chunks are the only thing preventing it from hallucinating a destructive terminal command.

---

🤖 8. OpenClaw (The Autonomous Viral Agent)

OpenClaw operates autonomously 24/7 in the background, executing tasks and interacting via messaging apps like WhatsApp, Telegram, or Discord. Because it is a persistent agent capable of executing terminal commands directly on your machine, feeding it dirty, unstructured context is a security risk. CodexMemory mathematically constraints its vision, ensuring it only acts on verified codebase logic.

The Autonomous Injection:

1. OpenClaw configuration is primarily handled via its command-line interface (CLI) to ensure safety.
2. Open your terminal and register CodexMemory as a core tool provider using OpenClaw's configuration schema (ensure the path is absolute):

# 1. Register the executable command
openclaw config set mcp.servers.codexmemory.command "/Users/YOUR_USER/.codexmemory_engine/bin/python"

# 2. Pass the startup server arguments
openclaw config set mcp.servers.codexmemory.args '["-m", "codexmemory.mcp_server"]'

# 3. Restart the OpenClaw gateway connection
openclaw gateway restart

3. Test the integration directly in your connected messaging app (e.g., WhatsApp) by asking: "Deep search the authentication logic and explain the middleware dependencies." Watch OpenClaw execute a sub-50ms retrieval, map the architecture locally, and text you the exact blueprint.

🛠️ The 3 Core AI Search Tools

The MCP server exposes 3 distinct tools to the LLM agent, replacing standard file exploration:

1. resonance_search (Primary Tool - Use 95% of the time)

• What it does: Searches the project memory using BM25S Hybrid retrieval (Semantic + Keyword RRF Fusion) and returns the exact matching "Holographic Splice" of code.
• Cost: ~500 tokens
• Example: "How does the stripe webhook validation work?"

2. inspect_canvas (Secondary Tool - Use 4% of the time)

• What it does: Projects the FULL content of a specific file, alongside its blueprint and dependency graph (what it imports and what imports it).
• Cost: ~2,000-5,000 tokens
• Use when: The AI needs to rewrite or profoundly refactor an entire file top-to-bottom.

3. deep_search (The Nuclear Option - Use 1% of the time)

• What it does: Searches project memory AND returns the full source code of multiple matching files at once, including all their dependency maps.
• Cost: ~10,000+ tokens
• Use when: Performing complex, cross-boundary architectural refactoring where 3+ systems must be understood simultaneously.

---

🧩 Supported Languages (AST Parsing)

CodexMemory natively understands and mathematically chunks 40+ file extensions using Tree-Sitter parsing:

• Python: .py, .pyi, .pyx
• JS/TS: .js, .jsx, .ts, .tsx, .mjs, .cjs
• Web: .html, .css, .scss, .vue, .svelte
