Overview

What is Mcp Code Executor Server?

Mcp Code Executor Server is a Model Context Protocol (MCP) server that enables AI agents to execute code across multiple programming languages in a secure, isolated environment. It standardizes how AI models connect to various programming runtimes by exposing a unified MCP tool endpoint. The server is for developers integrating code execution capabilities into AI workflows.

How to use Mcp Code Executor Server?

Clone the repository, build with ./mvnw clean package, and start the server with ./mvnw spring-boot:run. The server listens on port 8080 by default. Alternatively, run via Docker using docker build -t mcp-code-executor . and docker run -p 8080:8080 mcp-code-executor. Connect an MCP-compatible AI client to http://localhost:8080 and invoke the code-execution tool with a JSON payload specifying language and code.

Key features of Mcp Code Executor Server

  • Multi-language support: Java, Python, JavaScript, TypeScript, C++
  • Secure execution in isolated containers with resource limits
  • MCP integration for seamless client discovery
  • Automatic compilation for Java, C++, and TypeScript
  • Detailed compile-time and runtime error feedback
  • Automatic cleanup of temporary files and execution timeouts

Use cases of Mcp Code Executor Server

  • AI assistants executing code snippets in a sandboxed environment
  • Automated testing of code in multiple languages from a single interface
  • Providing AI agents with runtime feedback to refine code generation
  • Enabling multi-language code evaluation in educational AI tools
  • Integrating code execution into MCP-compatible client workflows

Frequently asked questions

1

Which programming languages are supported?

Java, Python, JavaScript, TypeScript, and C++.

2

How does the server ensure secure code execution?

It uses isolated containers with resource limits on CPU, memory, and timeouts, and automatically deletes temporary files.

3

What are the prerequisites to run the server locally?

Java 17+, Python 3.8+, Node.js & npm, and a C++ compiler (g++).

4

Can I run the server in a container for additional isolation?

Yes, the README provides Docker and Docker Compose instructions for running the server in a container.

5

How do I connect an MCP client to the server?

Start your MCP-compatible AI client and point it to `http://localhost:8080` to discover and invoke the `code-execution` tool.
