pub const fn with_tools_and_changes(self) -> Self

Enable tool support with change notifications.

pub fn with_resources(self) -> Self

Enable resource support.

pub const fn with_resources_and_subscriptions(self) -> Self

Enable resource support with subscriptions.

pub fn with_prompts(self) -> Self

Enable prompt support.

pub fn with_tasks(self) -> Self

Enable task support.

pub const fn with_logging(self) -> Self

Enable logging support.

pub const fn with_completions(self) -> Self

pub const fn has_tools(&self) -> bool

Check if tools are supported.

pub const fn has_resources(&self) -> bool

Check if resources are supported.

pub const fn has_prompts(&self) -> bool

Check if prompts are supported.

pub const fn has_tasks(&self) -> bool

Check if tasks are supported.

pub const fn has_completions(&self) -> bool

Check if completions are supported.

pub fn has_resource_subscribe(&self) -> bool

Check if resource subscriptions are supported.

pub fn with_extensions(self, registry: ExtensionRegistry) -> Self

Set extensions from an extension registry.

This populates the experimental field with extension declarations.

Arguments

• registry - The extension registry containing extensions to advertise

Example

use mcpkit_core::capability::ServerCapabilities;
use mcpkit_core::extension::{Extension, ExtensionRegistry};

let registry = ExtensionRegistry::new()
    .register(Extension::new("io.mcp.apps").with_version("0.1.0"));

let caps = ServerCapabilities::new()
    .with_tools()
    .with_extensions(registry);

assert!(caps.has_extension("io.mcp.apps"));

pub fn has_extension(&self, name: &str) -> bool

Check if a specific extension is supported.

Arguments

• name - The extension name to check

pub fn extensions(&self) -> Option<ExtensionRegistry>

Get the extension registry from capabilities.

Returns None if no extensions are declared or if parsing fails.
