Fields

description: Option<String>

An optional human-readable description of what this implementation does. This can be used by clients or servers to provide context about their purpose and capabilities. For example, a server might describe the types of resources or tools it provides, while a client might describe its intended use case.

icons: Vec<Icon>

Optional set of sized icons that the client can display in a user interface. Clients that support rendering icons MUST support at least the following MIME types: - image/png - PNG images (safe, universal compatibility) - image/jpeg (and image/jpg) - JPEG images (safe, universal compatibility) Clients that support rendering icons SHOULD also support: - image/svg+xml - SVG images (scalable but requires security precautions) - image/webp - WebP images (modern, efficient format)

name: String

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

title: Option<String>

Intended for UI and end-user contexts — optimized to be human-readable and easily understood, even by those unfamiliar with domain-specific terminology. If not provided, the name should be used for display (except for Tool, where annotations.title should be given precedence over using name, if present).

version: String

website_url: Option<String>

An optional URL of the website for this implementation.
