Struct InitializeResult 

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

Initialize response.

Backward Compatibility

This struct is #[non_exhaustive]. Use the constructor to remain forward-compatible:

use pmcp::types::protocol::{InitializeResult, Implementation};
use pmcp::ServerCapabilities;

let result = InitializeResult::new(
    Implementation::new("my-server", "1.0.0"),
    ServerCapabilities::tools_only(),
).with_instructions("Use this server for ...");

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

Negotiated protocol version

capabilities: ServerCapabilities

Server capabilities

server_info: Implementation

Server implementation info

instructions: Option<String>

Optional instructions

Implementations

impl InitializeResult

pub fn new( server_info: Implementation, capabilities: ServerCapabilities, ) -> Self

Create an initialize result with the default protocol version.

Instructions default to None.

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

Set optional instructions for the client.
