gm-exec

# gm-exec Code execution tool for MCP clients and CLI. Multi-language support (JS/TS, Python, Go, Rust, C, C++, Deno, Java, bash). Built on Bun with PM2-managed process isolation. ## MCP Server Add to your MCP client config: ```json { "mcpServers": { "gm-exec": { "command": "bunx", "args": ["gm-exec", "--mcp"] } } } ``` Or install globally: ```bash bun install -g gm-exec gm-exec --mcp ``` ## CLI ```bash bunx gm-exec-cli exec --cwd=/app "console.log('hello')" bunx gm-exec-cli bash --cwd=/app "npm install && npm test" bunx gm-exec-cli exec --lang=python --cwd=/app "print('hello')" bunx gm-exec-cli exec --file=script.js ``` ### Commands ``` gm-exec-cli exec [options] <code> Execute code (waits up to 15s, then backgrounds) --lang=<lang> nodejs (default), python, go, rust, c, cpp, java, deno --cwd=<dir> Working directory --file=<path> Read code from file gm-exec-cli bash [--cwd=<dir>] <cmd> Execute bash commands, same 15s ceiling gm-exec-cli status <task_id> Poll status + drain output of a background task gm-exec-cli close <task_id> Delete a background task gm-exec-cli runner start Start the runner manually (PM2, no autorestart) gm-exec-cli runner stop Stop the runner gm-exec-cli runner status Show runner PM2 status ``` ### Background execution Commands have a hard 15-second ceiling. If still running after that, the process is backgrounded and you get a task ID with monitoring instructions: ``` Backgrounded after 15s — task still running. Task ID: task_3 Watch output: gm-exec-cli status task_3 gm-exec-cli close task_3 gm-exec-cli runner stop ``` The runner auto-starts before each command and auto-stops after — unless a task was backgrounded, in which case the runner stays alive until you explicitly stop it. ## Supported Languages | Language | Runtime | |----------|---------| | JavaScript / TypeScript | Node.js / Bun | | Python | python3 | | Go | go run | | Rust | rustc | | C | gcc | | C++ | g++ | | Java | javac + java | | Deno | deno run | | bash / sh / zsh | shell | ## Requirements - [Bun](https://bun.sh) ≥ 1.0 ```bash curl -fsSL https://bun.sh/install | bash ```
