    FormElicitationParams {

Re-exports of the rmcp wire-protocol types this crate now surfaces directly instead of wrapping. Pull these in to pattern-match on tool annotations, content blocks, structured tool output, embedded resources, sampling / elicitation requests, progress and log notifications, etc. Parameters for creating an elicitation request to gather user input.

This structure contains everything needed to request interactive input from a user:

• A human-readable message explaining what information is needed
• A type-safe schema defining the expected structure of the response

Example

1. Form-based elicitation request

use rmcp::model::*;

let params = CreateElicitationRequestParams::FormElicitationParams {
   meta: None,
    message: "Please provide your email".to_string(),
    requested_schema: ElicitationSchema::builder()
        .required_email("email")
        .build()
        .unwrap(),
};

2. URL-based elicitation request

use rmcp::model::*;
let params = CreateElicitationRequestParams::UrlElicitationParams {
    meta: None,
    message: "Please provide your feedback at the following URL".to_string(),
    url: "https://example.com/feedback".to_string(),
    elicitation_id: "unique-id-123".to_string(),
};

Variants

FormElicitationParams

Fields

meta: Option<Meta>

Protocol-level metadata for this request (SEP-1319)

message: String

Human-readable message explaining what input is needed from the user. This should be clear and provide sufficient context for the user to understand what information they need to provide.

requested_schema: ElicitationSchema

Type-safe schema defining the expected structure and validation rules for the user’s response. This enforces the MCP 2025-06-18 specification that elicitation schemas must be objects with primitive-typed properties.

UrlElicitationParams

Fields

meta: Option<Meta>

Protocol-level metadata for this request (SEP-1319)

message: String

Human-readable message explaining what input is needed from the user. This should be clear and provide sufficient context for the user to understand what information they need to provide.

url: String

The URL where the user can provide the requested information. The client should direct the user to this URL to complete the elicitation.

elicitation_id: String

The unique identifier for this elicitation request.

Trait Implementations

impl Clone for CreateElicitationRequestParams

fn clone(&self) -> CreateElicitationRequestParams

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CreateElicitationRequestParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

impl<'de> Deserialize<'de> for CreateElicitationRequestParams

fn deserialize<__D>( __deserializer: __D, ) -> Result<CreateElicitationRequestParams, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CreateElicitationRequestParams

fn eq(&self, other: &CreateElicitationRequestParams) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for CreateElicitationRequestParams

impl TryFrom<CreateElicitationRequestParamDeserializeHelper> for CreateElicitationRequestParams

type Error = Error

The type returned in the event of a conversion error.

fn try_from( value: CreateElicitationRequestParamDeserializeHelper, ) -> Result<CreateElicitationRequestParams, <CreateElicitationRequestParams as TryFrom<CreateElicitationRequestParamDeserializeHelper>>::Error>

Performs the conversion.
