AgentExecMCP

What it is

An execution sandbox for agents, packaged as a Docker container. Three tools: run a shell command, run a code snippet in one of three languages, or install a package. Because it all happens inside the container, a bad command hits the container rather than your filesystem.

What you get

• shell runs a bash command with a timeout and a working directory, under safety controls
• execute_code runs a Python, Node.js or Go snippet, creating and cleaning up the temporary files itself and returning compilation as well as runtime errors
• install_package adds a dependency through pip, npm or go modules, with an optional version
• A prepared environment rather than a bare image: Ubuntu 22.04 with Python 3.13.3, Node.js 20.19.2 and Go 1.23.4, plus git, curl, wget, build-essential, jq, ripgrep, fd-find and htop
• Safety controls that come with the container — non-root execution, timeouts and concurrency limits
• Two transports: stdio for a local client, and SSE for HTTP deployment

Requirements

Docker. A Makefile wraps the setup — make quick-start builds the container and runs it with SSE transport, and other targets handle the Claude Desktop config. For local development the project uses uv sync and runs the module directly, with MCP_TRANSPORT=sse to switch transport. The SSE endpoint is http://localhost:8000/sse. The server implements the MCP 2024-11-05 specification.

Setup effort

Build from source

Tools you get

3 tools named in the project's documentation.

Requires

• Docker (for containerized deployment)
• Python 3.12+ (for local development)
• UV package manager (for dependency management)
• Node.js and npm (for Claude Desktop integration)

Where it runs

Both documented clients run the server on your machine.
