Struct InitializeResult 

#[non_exhaustive]
pub struct InitializeResult {
    pub protocol_version: ProtocolVersion,
    pub capabilities: ServerCapabilities,
    pub server_info: Implementation,
    pub instructions: Option<String>,
    pub meta: Option<MetaObject>,
}

Available on crate features mcp and tools only.

The server’s response to an initialization request.

Contains the server’s protocol version, capabilities, and implementation information, along with optional instructions for the client.

Fields (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.

protocol_version: ProtocolVersion

The MCP protocol version this server supports

capabilities: ServerCapabilities

The capabilities this server provides (tools, resources, prompts, etc.)

server_info: Implementation

Information about the server implementation

instructions: Option<String>

Optional human-readable instructions about using this server

meta: Option<MetaObject>

Implementations

impl InitializeResult

pub fn new(capabilities: ServerCapabilities) -> InitializeResult

Create a new InitializeResult with default protocol version and the given capabilities.

pub fn with_instructions( self, instructions: impl Into<String>, ) -> InitializeResult

Set instructions on this result.

pub fn with_server_info(self, server_info: Implementation) -> InitializeResult

Set the server info on this result.

pub fn with_protocol_version( self, protocol_version: ProtocolVersion, ) -> InitializeResult

Set the protocol version on this result.

Trait Implementations

impl Clone for InitializeResult

fn clone(&self) -> InitializeResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InitializeResult

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

Formats the value using the given formatter.

impl Default for InitializeResult

fn default() -> InitializeResult

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for InitializeResult

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<InitializeResult> for ServerPeerInfo

fn from(result: InitializeResult) -> ServerPeerInfo

Converts to this type from the input type.

impl From<InitializeResult> for ServerResult

fn from(value: InitializeResult) -> ServerResult

Converts to this type from the input type.

impl JsonSchema for InitializeResult

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for InitializeResult

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for InitializeResult

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.
