Host Secure MCP Servers for AI Assistants
Run MCP tools in isolated sandboxes. Give Claude, Cursor, and other AI assistants safe code execution capabilities. ~100ms startup, complete isolation.
Give AI Assistants Real Capabilities
MCP (Model Context Protocol) lets AI assistants use tools and execute actions. But running tools safely requires proper isolation:
- ✗Running MCP tools on your machine exposes your system
- ✗AI-generated code could access sensitive files
- ✗No easy way to sandbox MCP servers
- ✗Resource limits hard to enforce locally
Hopx MCP Server
- ✓Code executes in isolated cloud sandboxes, not your machine
- ✓Pre-built MCP server with code execution tools
- ✓Works with Claude Desktop, Cursor, VS Code, and more
- ✓5-minute setup — just configure and go
Works With Your Favorite Tools
The Hopx MCP server integrates with any client that supports the Model Context Protocol.
What MCP Tools Can Do
Code Execution Tools
Let AI assistants run code safely in sandboxes
File System Tools

Custom Business Tools
Build domain-specific tools for your workflows
Why Hopx for MCP
Per-Server Isolation
Each MCP server runs in its own micro-VM. Complete network and filesystem isolation between tools.
~100ms Startup
MCP servers start almost instantly. No cold start delays when your AI assistant needs a tool.
Safe Port Exposure
Expose ports securely for tool endpoints. Control exactly what's accessible from outside the sandbox.
Controlled Permissions
Define what each MCP server can access — network, filesystem, external APIs. Principle of least privilege.
Set Up in 5 Minutes
Install the Hopx MCP server, add your API key, and your AI assistant can execute code safely in cloud sandboxes.
Pre-built Server
No need to build your own MCP server — we've done it
Secure by Default
All code runs in isolated sandboxes, not on your machine
Instant Execution
~100ms sandbox startup — no waiting for your AI
