model-context-shell: Unix-style pipelines for MCP. Deterministic tool calls
Summary
Model Context Shell enables AI agents to orchestrate MCP tool calls using Unix-style pipelines, reducing the amount of intermediate data loaded into context and enabling deterministic, server-side execution. It introduces pipeline-based execution with tool, command, and preview stages, along with four MCP-facing tools, security constraints, and ToolHive integration. The project is framed as a living RFC and a practical demo with setup guidance and testing options.
