Description

Riza MCP server provides secure, sandboxed code execution environments for AI-generated code. When an LLM needs to run code — whether Python, JavaScript, or other languages — Riza executes it in isolated containers with strict security boundaries. This solves the fundamental trust problem of AI code generation: you get the power of executable code without the risk of running untrusted programs on your machine. The MCP server exposes tools for executing code, creating reusable tools, and managing sandbox environments, making it a critical safety layer for any AI workflow that involves code generation and execution.

✅ Best for

Teams that need secure execution of AI-generated code without local security risks

⏭️ Skip if

You only need to run trusted, pre-reviewed code or prefer fully local execution

💡 Use cases

Safely executing AI-generated code in sandboxed environments from AI assistants
Building custom tools that LLMs can invoke with dynamic code execution
Running data analysis scripts generated by AI without local security risks
Prototyping and testing code snippets in isolated containers through conversational AI

👍 Pros

✓ Secure sandboxed execution eliminates risks of running untrusted AI-generated code
✓ Multi-language support (Python, JavaScript, and more) in isolated containers
✓ Simple npx installation with API key authentication
✓ Critical safety layer for AI-driven development workflows

👎 Cons

✗ Requires Riza API key and account (cloud-dependent execution)
✗ Execution latency higher than local code runs due to container overhead
✗ Sandbox limitations may restrict access to certain libraries or system resources

🔧 Exposed tools (4 tools)

Tool	Category	Description
execute_code	execution	Execute code in a secure sandboxed environment
create_tool	management	Create a reusable tool from code that LLMs can invoke
list_tools	management	List all available tools created in the Riza platform
manage_sandbox	management	Configure and manage sandbox execution environments

⚡ Installation

Prerequisites:

• Node.js v18+
• Riza API key
• API key required

Check Claude Code documentation to configure this MCP server.

💡 Tips & tricks

Set RIZA_API_KEY in your environment before starting. Use execute_code for one-off scripts and create_tool when you want to build reusable functions the AI can call repeatedly. Check supported languages and available libraries in the Riza documentation before building complex execution workflows.
