Unix-style pipeline composition for MCP tool calls
The project implements a sandboxed, server-side 'shell' that pipes MCP tool calls together so agents return only final outputs — a smart way to save tokens and handle datasets too large for LLM context. The repo includes a demo video, tests, and a real shell_engine/mcp_client implementation, but it's a focused infra play for the MCP ecosystem and will matter most to teams building agent platforms rather than general devs.
