MCP Server
An MCP server is a program that exposes tools, resources, and prompts to AI assistants through the Model Context Protocol. MCP servers act as bridges between AI models and external systems — databases, APIs, file systems, or knowledge bases — allowing AI to interact with them through a standardized interface.
Model Context Protocol (MCP)
Model Context Protocol (MCP) is an open standard created by Anthropic that enables AI assistants to connect with external data sources and tools through a unified interface. It provides a standardized way for AI models to access context, execute tools, and interact with services without custom integrations for each provider.
