What is MCP Server?
MCP Server is a Dart plugin that enables Flutter applications to act as servers within the Model Context Protocol (MCP) ecosystem. It provides a standardized way to expose data, functionality, and interaction patterns to Large Language Models (LLMs).
How to use MCP Server?
To use MCP Server, add the package to your pubspec.yaml
file and install it. Then, create an McpServer
instance, add resources, tools, and prompts to it, and connect it to a transport layer (Standard I/O or Server-Sent Events). The provided code examples demonstrate how to define and add resources, tools, and prompts to the server.
