Setup snapshot

  1. 1

    Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Flow Data Types Messages Text Content Image Content Audio Content Model Preferences Capability Priorities Model Hints Error Handling Security Considerations Client Features Sampling Copy page Copy page The Model Context Protocol (MCP) provides a standardized way for servers to request LLM sampling (“completions” or “generations”) from language models via clients. This flow allows clients to maintain control over model access, selection, and permissions while enabling servers to leverage AI capabilities—with no server API keys necessary. Servers can request text, audio, or image-based interactions and optionally include context from MCP servers in their prompts. ​ User Interaction Model Sampling in MCP allows servers to implement agentic behaviors, by enabling LLM calls to occur nested inside other MCP server features. Implementations are free to expose sampling through any interface patt
