MCP demo

According to Model Cpntext Protocal(MCP) official documents, MCP is an open protocal that standardizes how applications provide context to LLMs.

MCP follows client-server architecture

Hosts: LLM applications.
Clients: maintain 1:1 connection with servers.
Servers: provide context, tools, prompts to clients.

MCP key features

Resources: allow server to expose static data and content that can be read by clients.
Prompts: provide consistent and reusable prompt template for LLM interactions.
Tools: executable functions that can be called by LLMs and perform actions or operations. Then the results will be used by clients.
