MCP Vault: Secure Gateway & Booster for Antigravity

⚡ MCP Vault (mcpv)

The Ultimate Performance Booster for AI Agents
"Reduce system lag by 99%, eliminate loading times, and cut token costs by 90%."

🇰🇷 한국어 | 🇨🇳 中文 | 🇷🇺 Русский

[!CAUTION] ⚠️ Compatibility Warning
Currently, this project ONLY supports Windows OS and the Antigravity agent environment.

❓ Why mcpv?

Have you ever felt this while using AI Agents (Antigravity, Cursor)?

"Why is it so heavy?"
"It froze again..."
"Why are the token costs so high?"

mcpv is not just a tool. It is a Turbo Engine for your agent.

🏎️ Overwhelming Performance Difference

Feature	😫 Without mcpv (Before)	⚡ With mcpv (After)	📈 Effect
Speed	No GPU, Laggy UI	Forced GPU Acceleration, Smooth	100x Perceived Speed
Loading	Wait 60s+ every time	0.1s Instant Start (Lazy Load)	Zero Latency
Cost	Resend full code every time	Auto-block Duplicates (Smart Cache)	90% Savings

✨ 3 Core Features

1️⃣ Booster Injection (Physical Acceleration)

"Unlock hardware limits with one line"

• Forced GPU Activation: Injects hidden rendering acceleration flags (--enable-gpu-rasterization).
• Permission Bypass: Drops Admin rights to fix drag-and-drop & UI bugs, and bypasses permission requests (Error 740) using RunAsInvoker.
• Zombie Process Killer: Automatically cleans up ghost processes occupying ports.

2️⃣ Smart Valve (Cost Defense)

"Smart wallet protector that saves for you"

• Detects the massive context data (repomix) that agents habitually request.
• First request: Allowed (Full context provided).
• Subsequent requests: Blocked with a 10-token "Already cached" message.
• Physically blocks accidental token bombs.

3️⃣ Gateway Hijacking (Secure Vault)

"Stop struggling with complex configs"

• Zero-Latency Startup: Only scans directories when the agent actually requests them. No timeouts on large repos.
• Automatically migrates existing complex MCP settings to a secure Vault.
• Original config is safely backed up to mcp_config.original.json.
• The agent talks only to mcpv, but all tools work perfectly behind the scenes.

🛠️ Verified Recommended Setup

Verified MCP server configuration used by the developer. It creates the best synergy when used with mcpv.

{
  "mcpServers": {
    "rube": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://rube.app/mcp"]
    },
    "open-aware": {

� Recommended System Rule

Add this rule to your agent's system prompt (e.g., .cursorrules, .antigravityrules).
This ensures the agent uses mcpv correctly without redundant requests.

[System Instruction]

Session Start: At the very beginning of the conversation, you MUST call get_initial_context tool immediately. This is your only way to understand the project structure.

Context Management: Do NOT call get_initial_context again in the same session unless the user explicitly asks for a "refresh" with force=True. The proxy will block redundant requests.

File Access: After reading the initial context map, use read_file to inspect specific files needed for the task.

---

�🛠️ Tech Stack

• Python & uv: Uses uv for clean, isolated virtual environments to prevent dependency hell.
• FastMCP: Built on top of the FastMCP framework for speed.
• Gateway Pattern: It backs up your original config and routes traffic through the proxy securely.

📦 Installation

Choose the method that fits your needs.

Option A: The "It Just Works" Method (Recommended for most users)

If you have Python installed and added to PATH.

# 1. Install from PyPI
pip install mcpv

# 2. Setup Gateway & Booster
mcpv install

# 3. Done! 
# Look for the "Antigravity Boost (mcpv)" shortcut on your Desktop.

---

Option B: The "Rock-Solid" Method (Using uv)

Use this method if your Python environment is messy or you want complete isolation.

1. Clean up existing processes

Stop-Process -Name "mcpv" -Force -ErrorAction SilentlyContinue
Stop-Process -Name "python" -Force -ErrorAction SilentlyContinue

2. Create Virtual Environment & Install

# Install uv (if needed)
powershell -ExecutionPolicy ByPass -c "irm [https://astral.sh/uv/install.ps1](https://astral.sh/uv/install.ps1) | iex"

# Create .venv and install mcpv
uv venv
uv pip install mcpv

3. Register & Lock

This registers the isolated virtual environment into Antigravity's config.

.venv\Scripts\python -m mcpv install --force

4. Run

Launch Antigravity Boost (mcpv) from your Desktop.

🛠️ Commands

Command	Description
mcpv install	Installs the gateway and creates the Desktop shortcut.
mcpv install --force	Forces installation even if only 1 MCP server exists.
mcpv start	Starts the server (Used internally by Antigravity).
mcpv --help	Show help message.

---

❓ Troubleshooting

Q. "File access denied" or "Failed to remove file" during update?

This means mcpv.exe or Antigravity is still running.

1. Close Antigravity.
2. Run: Stop-Process -Name "mcpv" -Force in PowerShell.
3. Try installing again.

Q. I installed it, but I don't see the Shortcut.

The shortcut is created on your Desktop. If not, check the installation logs. You can create it manually by running mcpv install again.
