👎Deprecated since 2.0.0:

Sampling is deprecated by SEP-2577 and will be removed in a future release. See https://github.com/modelcontextprotocol/modelcontextprotocol/pull/2577

Available on crate features mcp and tools only.
Expand description

Preferences for model selection and behavior in sampling requests.

This allows servers to express their preferences for which model to use and how to balance different priorities when the client has multiple model options available.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§hints: Option<Vec<ModelHint>>
👎Deprecated since 2.0.0:

Sampling is deprecated by SEP-2577 and will be removed in a future release. See https://github.com/modelcontextprotocol/modelcontextprotocol/pull/2577

Specific model names or families to prefer (e.g., “claude”, “gpt”)

§cost_priority: Option<f32>
👎Deprecated since 2.0.0:

Sampling is deprecated by SEP-2577 and will be removed in a future release. See https://github.com/modelcontextprotocol/modelcontextprotocol/pull/2577

Priority for cost optimization (0.0 to 1.0, higher = prefer cheaper models)

§speed_priority: Option<f32>
👎Deprecated since 2.0.0:

Sampling is deprecated by SEP-2577 and will be removed in a future release. See https://github.com/modelcontextprotocol/modelcontextprotocol/pull/2577

Priority for speed/latency (0.0 to 1.0, higher = prefer faster models)

§intelligence_priority: Option<f32>
👎Deprecated since 2.0.0:

Sampling is deprecated by SEP-2577 and will be removed in a future release. See https://github.com/modelcontextprotocol/modelcontextprotocol/pull/2577

Priority for intelligence/capability (0.0 to 1.0, higher = prefer more capable models)
