Struct InitializeRequest

pub struct InitializeRequest {
    pub protocol_version: ProtocolVersion,
    pub capabilities: Capabilities,
    pub client_info: Implementation,
}

Client-to-server initialization request.

This is the first message sent by the client to establish the MCP session. It includes the desired protocol version, client capabilities, and client metadata.

Fields

protocol_version: ProtocolVersion

Protocol version requested by the client

capabilities: Capabilities

Capabilities offered by the client

client_info: Implementation

Information about the client implementation

Implementations

impl InitializeRequest

pub fn new( protocol_version: ProtocolVersion, capabilities: Capabilities, client_info: Implementation, ) -> Self

Create a new initialization request.

Examples

use mcp_probe_core::messages::{InitializeRequest, ProtocolVersion, Capabilities, Implementation};

let request = InitializeRequest::new(
    ProtocolVersion::V2024_11_05,
    Capabilities::default(),
    Implementation::new("my-client", "1.0.0"),
);

pub fn basic( client_name: impl Into<String>, client_version: impl Into<String>, ) -> Self

Create a basic initialization request with default capabilities.

This is a convenience method for simple clients that don’t need to specify custom capabilities.

Examples

use mcp_probe_core::messages::InitializeRequest;

let request = InitializeRequest::basic("my-client", "1.0.0");

pub fn with_client_metadata(self, key: impl Into<String>, value: Value) -> Self

Add custom client metadata to the initialization request.

Examples

use mcp_probe_core::messages::InitializeRequest;
use serde_json::json;

let request = InitializeRequest::basic("my-client", "1.0.0")
    .with_client_metadata("platform", json!("rust"))
    .with_client_metadata("os", json!("linux"));

pub fn is_supported_version(&self) -> bool

Check if the requested protocol version is supported.

Trait Implementations

impl Clone for InitializeRequest

fn clone(&self) -> InitializeRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InitializeRequest

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InitializeRequest

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for InitializeRequest

fn eq(&self, other: &InitializeRequest) -> 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.

impl Serialize for InitializeRequest

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
