MemoV is a memory layer for AI coding agents that provides traceable, Git-powered version control for prompts, context, and code diffs. It enables VibeGit - automatic versioning of AI coding sessions with branch exploration, rollback capabilities, and zero pollution to the standard .git repository.

MemoV	Checkpoints
Branch exploration	Linear timeline
Cross-session	Session-bound
Rollback preserves all	Rollback erases history
Every jump tracked	No trajectory

Features

• One-click MCP: Works with any AI coding agent
• VibeGit for Agents: Auto-trace prompts, context, and code diffs before git commits
• Version Control: Branch, rollback, replay any interaction
• Keep Git Clean: Shadow .mem timeline, files as context, zero pollution on .git
• Visual UI: Say "mem ui" in chat, and view at http://localhost:38888
• Private-first — Local, no database, no overhead. Use .memignore to exclude

Quick Start (MCP Installation)

Prerequisites

Install uv first:

# macOS / Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

# Install Git (if not installed)
winget install --id Git.Git -e --source winget

Claude Code

Run in your project root directory:

claude mcp add mem-mcp --scope project -- uvx --from git+https://github.com/memovai/memov.git mem-mcp-launcher stdio $(pwd)

Codex

Run in your project root directory:

codex mcp add mem-mcp -- uvx --from git+https://github.com/memovai/memov.git mem-mcp-launcher stdio $(pwd)

Create .vscode/mcp.json in your project root:

{
  "servers": {
    "mem-mcp": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/memovai/memov.git",
        "mem-mcp-launcher",
        "stdio",
        "${workspaceFolder}"
      ]
    }
  }
}

Go to Files > Preferences > Cursor Settings > MCP, then add:

{
  "mcpServers": {
    "mem-mcp": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/memovai/memov.git",
        "mem-mcp-launcher",
        "stdio",
        "${workspaceFolder}"
      ]
    }
  }
}

Note: Antigravity does not support "${workspaceFolder}" variable. Please manually enter the absolute path to your project directory.

Go to Settings > MCP, then add:

{
  "mcpServers": {
    "mem-mcp": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/memovai/memov.git",
        "mem-mcp-launcher",
        "stdio",
        "/absolute/path/to/your/project"
      ]
    }
  }
}

Replace /absolute/path/to/your/project with the actual absolute path to your project directory (e.g., /Users/username/projects/my-project on macOS/Linux or C:\\Users\\username\\projects\\my-project on Windows).

To enable semantic search, validation, and debugging tools, install with [rag] extras:

Claude Code:

claude mcp add mem-mcp --scope project -- uvx --from "git+https://github.com/memovai/memov.git[rag]" mem-mcp-launcher stdio $(pwd)

VS Code / Cursor: Change the --from argument to:

"git+https://github.com/memovai/memov.git[rag]"

Important Tips

Add a Rule — To automatically save snapshots after each interaction, add a rule to your coding agents:

• Cursor: Cursor Settings > Rules
• Claude Code: CLAUDE.md
• Or the equivalent in your MCP client

Example rule:

After completing any interaction, always call `use mem snap` to save the snapshot.

Web UI, Just Say Use mem ui🤌

Just say "use mem ui" in the chat — opens at http://localhost:38888 with timeline view, branch filtering, diff viewer, and jump to any snapshot.

CLI Installation (Optional)

If you want to use the mem CLI tool directly (for manual tracking, history viewing, etc.):

Architecture

MemoV follows a three-tier architecture with MemovManager as the central orchestrator, the MCP Server as an adapter layer for AI agents, and an optional RAG system for semantic search.

Core Operations

• snap(user_prompt: str, original_response: str, agent_plan: list[str], files_changed: str)

  • Record every user interaction with automatic file tracking. Handles untracked vs modified files intelligently.

• mem_ui(port: int = 38888)

  • Launch the Web UI at http://localhost:38888 to visually browse history, view diffs, and jump to any snapshot.

• mem_history(limit: int = 20, commit_hash: str = "")

  • View memov history with prompts, responses, and file changes.

• mem_jump(commit_hash: str)

  • Jump to a specific snapshot, restoring all tracked files and creating a new branch.

RAG Tools (requires [rag] extras)

These tools are only available when installed with [rag] extras.

• mem_sync()

  • Sync all pending operations to VectorDB for semantic search capabilities.

• validate_commit(commit_hash: str, detailed: bool = True)

  • Validate a specific commit by comparing prompt/response with actual code changes. Detects context drift and alignment issues.

• validate_recent(n: int = 5)

  • Validate the N most recent commits for alignment patterns. Useful for session reviews and quality assurance.

• vibe_debug(query: str, error_message: str = "", stack_trace: str = "", user_logs: str = "", models: str = "", n_results: int = 5)

  • Debug issues using RAG search + multi-model LLM comparison. Searches code history for relevant context and queries multiple AI models (GPT-4, Claude, Gemini) in parallel for diverse debugging insights.

• vibe_search(query: str, n_results: int = 5, content_type: str = "")

  • Fast semantic search through code history (prompts, responses, agent plans, code changes) without LLM analysis. Perfect for quick context lookup.

Health Check

• GET /health
  • Returns "OK". Useful for IDE/agent readiness checks.
