Overview

MCP Tools is a versatile command-line interface for interacting with MCP (Model Context Protocol) servers. It enables users to discover, call, and manage tools, resources, and prompts from any MCP-compatible server across multiple transport methods including stdio and HTTP. The tool offers a rich set of features including an interactive shell mode, web interface, project scaffolding capabilities, and various output formats (table, JSON, pretty). It also provides specialized server modes for mocking, proxying, and guarding MCP requests.
