Deno MCP Server

Example Use Cases

• 1

  Run arbitrary Deno TypeScript/JavaScript snippets and capture console output or results.

Description

This MCP server runs Deno TypeScript/JavaScript code on demand, allowing agents to request execution with fine-grained permissions (net, read, write, env, run, etc.) and optional unstable features. It integrates with Claude Desktop and Cline via MCP configuration and provides tools for executing code and checking the installed Deno version. The server enforces a 30-second execution timeout to limit long-running tasks and helps LLMs perform tasks like HTTP requests, file I/O, and running subprocesses securely.
