    pub name: String,
    pub version: String,
    pub title: Option<String>,

Information about an MCP implementation (2025-11-25 with title support)

Fields

name: String

Intended for programmatic or logical use, but used as a display name in past specs or fallback (if title isn’t present).

version: String

Version of the implementation

title: Option<String>

Intended for UI and end-user contexts — improved to be human-readable and easily understood, even by those unfamiliar with domain-specific terminology.

description: Option<String>

Optional description for UI contexts.

website_url: Option<String>

Optional implementation website.

icons: Option<Vec<Icon>>

Optional UI icons.

Implementations

impl Implementation

pub fn new<S: Into<String>>(name: S, version: S) -> Self

Create a new implementation with name and version

pub fn with_title<S: Into<String>>(name: S, version: S, title: S) -> Self

Create implementation with title

pub fn with_description<S: Into<String>>(self, description: S) -> Self

Add an optional human-readable description.

pub fn with_website_url<S: Into<String>>(self, website_url: S) -> Self

Add the implementation website URL.

pub fn with_icons(self, icons: Vec<Icon>) -> Self

Add UI icons advertised by the implementation.

Trait Implementations

impl Clone for Implementation

fn clone(&self) -> Implementation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Implementation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Implementation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Implementation

fn eq(&self, other: &Implementation) -> 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 Implementation

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
