What is MCP Client Plugin?
This MCP Client Plugin is a modern, zero-dependency tool built specifically for Bun runtime to manage and communicate with MCP (Model Context Protocol) servers. It enables developers to start, stop, and interact with multiple MCP servers using a fluent, chainable API. The plugin supports both stdio and SSE transports, allowing local process management and remote server interactions seamlessly. Its pure functional and immutable design enhances predictability and reduces side effects. It offers features like server lifecycle control, resource reading, tool calling, and notification handling, all optimized for high performance. This plugin is suitable for developers seeking a lightweight, fast, and reliable MCP client that leverages Bun’s capabilities without any unnecessary dependencies.
