Riza MCP Server

What is Riza MCP Server about?

Riza MCP Server exposes the Riza code‑interpreter service through the Model Context Protocol (MCP) as a collection of individual tools that LLMs can invoke.

How to use Riza MCP Server?

1. Install the package via npx @riza-io/riza-mcp (no separate install required).
2. Provide your Riza API key through the environment variable RIZA_API_KEY.
3. Configure your MCP client (e.g., Claude Desktop) with the JSON snippet shown in the README, referencing the command and arguments.
4. Call the exposed tools (create_tool, fetch_tool, execute_tool, edit_tool, list_tools, execute_code) from the LLM.

Key features of Riza MCP Server

• create_tool – Save LLM‑generated code as a reusable tool via Riza’s Tools API.
• fetch_tool – Retrieve saved tool definitions and source code for inspection or editing.
• execute_tool – Run a stored tool securely on Riza’s isolated interpreter.
• edit_tool – Update the code or metadata of an existing tool.
• list_tools – Enumerate all tools owned by the provided API key.
• execute_code – Run ad‑hoc code instantly without persisting it as a tool.

Use cases of Riza MCP Server

• Enable autonomous agents to generate, test, and store reusable code snippets.
• Allow LLMs to safely execute user‑provided scripts in an isolated environment.
• Build tool‑driven workflows where each step is a distinct Riza‑hosted function.
• Rapid prototyping of code‑based utilities that can be versioned and invoked later.

FAQ from the Riza MCP Server

Q: Do I need to install any dependencies manually? A: No. The server runs directly with npx @riza-io/riza-mcp.

Q: Which environment variable holds the API key? A: RIZA_API_KEY.

Q: Can I execute arbitrary code without saving it? A: Yes, use the execute_code tool.

Q: Is the execution environment sandboxed? A: Execution is performed by Riza’s isolated code‑interpreter service, providing strong security guarantees.

Riza MCP Server

Riza offers an isolated code interpreter for your LLM-generated code.

Our MCP server implementation wraps the Riza API and presents endpoints as individual tools.

Configure with Claude Desktop as below, or adapt as necessary for your MCP client. Get a free Riza API key in your Riza Dashboard.

The Riza MCP server provides several tools to your LLM:

• create_tool: Your LLM can write code and save it as a tool using the Riza Tools API. It can then execute these tools securely on Riza using execute_tool.
• fetch_tool: Your LLM can fetch saved Riza tools, including source code, which can be useful for editing tools.
• execute_tool: Executes a saved tool securely on Riza's code interpreter API.
• edit_tool: Edits an existing saved tool.
• list_tools: Lists available saved tools.
• execute_code: Executes arbitrary code safely on Riza's code interpreter API, without saving it as a tool.
