What can you do with Riza MCP?

  • Create and save code as a reusable tool — ask the assistant to write code and persist it via create_tool for later secure execution.
  • Run arbitrary code in an isolated interpreter — use execute_code to safely execute one-off scripts without saving them.
  • List and inspect saved tools — retrieve all available tools with list_tools or fetch a specific tool’s source via fetch_tool.
  • Modify an existing tool — update a saved tool’s code using edit_tool.
  • Execute a saved tool on demand — run a previously created tool securely through execute_tool.

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.
