What is MCP
MCP (Model Context Protocol) is an open protocol open-sourced by Anthropic that enables seamless integration between large language model (LLM) applications and external data sources and tools. Based on a client-server architecture, it supports multiple services connecting to any compatible client, providing a standardized, universal protocol for sharing resources, tools, and prompts. MCP can access local and remote resources, has built-in security mechanisms, and protects API keys from being leaked. It is an important tool for building interconnected AI systems.
Main Features of MCP
- Data Integration: Connects AI assistants with various data sources, including local and remote resources.
- Tool Integration: Integrates APIs and other tools, enabling AI systems to perform more complex operations.
- Templated Interaction: Provides templated interaction methods based on Prompts.
- Security: Built-in security mechanisms protect data and API keys.
- Developer Support: Provides SDKs and documentation to support developers in building and testing MCP connectors.
- Pre-built Servers: Provides pre-built MCP servers for quickly integrating popular enterprise systems.
- Context Maintenance: Maintains context across different tools and datasets, enabling smarter task processing.
Technical Principles of MCP
- Client-Server Architecture：
- MCP Server: Acts as an adapter for data sources, exposing data and tools to AI clients.
- MCP Client: Contains AI tools or applications, such as Claude Desktop, which connect to MCP servers to access data.
- Standardized Protocol: Designs standardized request and response formats, allowing different AI systems to interact with various data sources in a consistent way.
- Secure Communication: Uses security mechanisms such as OAuth or API key management to ensure the security of data transmission and the confidentiality of API keys.
- Bidirectional Data Flow: Supports reading data from data sources to AI systems, and writing data from AI systems to data sources, enabling bidirectional interaction.
