Struct ElicitationSchema 

pub struct ElicitationSchema {
    pub type_: ObjectTypeConst,
    pub title: Option<Cow<'static, str>>,
    pub properties: BTreeMap<String, PrimitiveSchema>,
    pub required: Option<Vec<String>>,
    pub description: Option<Cow<'static, str>>,
}

Type-safe elicitation schema for requesting structured user input.

This enforces the MCP 2025-06-18 specification that elicitation schemas must be objects with primitive-typed properties.

Example

use rmcp::model::*;

let schema = ElicitationSchema::builder()
    .required_email("email")
    .required_integer("age", 0, 150)
    .optional_bool("newsletter", false)
    .build();

Fields

type_: ObjectTypeConst

Always “object” for elicitation schemas

title: Option<Cow<'static, str>>

Optional title for the schema

properties: BTreeMap<String, PrimitiveSchema>

Property definitions (must be primitive types)

required: Option<Vec<String>>

List of required property names

description: Option<Cow<'static, str>>

Optional description of what this schema represents

Implementations

impl ElicitationSchema

pub fn new(properties: BTreeMap<String, PrimitiveSchema>) -> ElicitationSchema

Create a new elicitation schema with the given properties

pub fn from_json_schema( schema: Map<String, Value>, ) -> Result<ElicitationSchema, Error>

Convert from a JSON Schema object (typically generated by schemars)

This allows converting from JsonObject to ElicitationSchema, which is useful when working with automatically generated schemas from types.

Example

use rmcp::model::*;

let json_schema = schema_for_type::<MyType>();
let elicitation_schema = ElicitationSchema::from_json_schema(json_schema)?;

Errors

Returns a serde_json::Error if the JSON object cannot be deserialized into a valid ElicitationSchema.

pub fn with_required(self, required: Vec<String>) -> ElicitationSchema

Set the required fields

pub fn with_title( self, title: impl Into<Cow<'static, str>>, ) -> ElicitationSchema

Set the title

pub fn with_description( self, description: impl Into<Cow<'static, str>>, ) -> ElicitationSchema

Set the description

pub fn builder() -> ElicitationSchemaBuilder

Create a builder for constructing elicitation schemas fluently
