Sampling And Llm Request Delegation From Server To Client

via “client-initiated request handling (sampling)”

Model Context Protocol implementation for TypeScript

Unique: Enables servers to act as agentic clients themselves by requesting LLM capabilities from connected clients, creating a two-way interaction model rather than traditional one-way tool invocation

vs others: More powerful than unidirectional tool calling because servers can delegate reasoning to the LLM and incorporate results into their own decision-making logic
