# Volta MCP — Node.js Version Manager for AI Tools

> Fast, reliable Node.js version manager that ensures MCP servers and AI tools always use the correct Node version. Cross-platform with zero-config project pinning.

## Install

Merge the JSON below into your `.mcp.json`:

## Quick Use

```bash
# Install Volta
curl https://get.volta.sh | bash

# Pin Node version for your project
volta pin node@20
volta pin npm@10

# Install global tools
volta install npx
```

Now every MCP server and AI tool in your project uses the pinned Node version.

## What is Volta?

Volta is a fast, cross-platform Node.js version manager that pins tool versions per project. When you run MCP servers or AI tools that depend on Node.js, Volta ensures they always use the correct version — no manual switching, no version conflicts, no broken npx commands.

**Answer-Ready**: Volta is a fast Node.js version manager that pins versions per project, ensuring MCP servers and AI tools always use the correct Node.js. Cross-platform (macOS/Linux/Windows) with zero-config project pinning. 12k+ GitHub stars.

**Best for**: Developers running MCP servers who need reliable Node.js version management. **Works with**: Any Node.js project, MCP servers, Claude Code, Cline. **Setup time**: Under 1 minute.

## Why Volta for MCP?

MCP servers often require specific Node.js versions. Common problems:

```
# Without Volta
$ npx -y @modelcontextprotocol/server-github
Error: This package requires Node.js >= 18.0.0

# With Volta
$ volta pin node@20
$ npx -y @modelcontextprotocol/server-github
✓ Server started successfully
```

## Core Features

### 1. Project Pinning
Pin Node version in `package.json`:

```json
{
  "volta": {
    "node": "20.11.0",
    "npm": "10.2.4"
  }
}
```

Everyone on the team uses the same version automatically.

### 2. Zero Switching
No need for `nvm use` — Volta auto-detects:

```bash
cd project-a/  # Uses Node 20 (pinned)
cd project-b/  # Uses Node 18 (pinned)
cd ~/           # Uses default Node version
```

### 3. Fast Execution
Written in Rust — near-instant version resolution:

```
nvm use:     ~200ms overhead per command
volta:       ~5ms overhead per command
```

### 4. Global Tool Isolation
Each global tool gets its own Node version:

```bash
volta install typescript    # Uses Node 20
volta install prettier      # Uses Node 18
# No conflicts — each tool pinned independently
```

### 5. Cross-Platform
Same behavior on macOS, Linux, and Windows (no WSL needed).

## MCP Server Setup with Volta

```bash
# 1. Install Volta
curl https://get.volta.sh | bash

# 2. Install Node.js
volta install node@20

# 3. MCP servers now work reliably
# .mcp.json
{
  "mcpServers": {
    "github": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-github"]
    }
  }
}
```

## FAQ

**Q: Can I use Volta with nvm?**
A: Not recommended — they conflict. Uninstall nvm first: remove nvm lines from your shell profile.

**Q: Does it work with pnpm/yarn?**
