Struct LogServer 

pub struct LogServer { /* private fields */ }

The MCP server: the four tools, one prompt and two resources over [rmcp].

Cheap to create and to clone; the HTTP transports create one per session. It holds nothing between calls.

Implementations

impl LogServer

pub fn new() -> Self

Trait Implementations

impl Clone for LogServer

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogServer

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

Formats the value using the given formatter.

impl Default for LogServer

fn default() -> Self

Returns the “default value” for a type.

impl ServerHandler for LogServer

async fn call_tool( &self, request: CallToolRequestParams, context: RequestContext<RoleServer>, ) -> Result<CallToolResponse, ErrorData>

A tool the server does not have is reported as a tool result, not a protocol error.

The SDK’s default is -32602, which the stateless HTTP revision carries as an HTTP 400 — a transport fault to the client, and nothing a model gets to read. A model that misspelt a tool name is better served by text saying so.

fn get_info(&self) -> ServerConfig

async fn list_prompts( &self, _request: Option<PaginatedRequestParams>, _context: RequestContext<RoleServer>, ) -> Result<ListPromptsResult, ErrorData>

async fn get_prompt( &self, request: GetPromptRequestParams, _context: RequestContext<RoleServer>, ) -> Result<GetPromptResponse, ErrorData>

async fn list_resources( &self, _request: Option<PaginatedRequestParams>, _context: RequestContext<RoleServer>, ) -> Result<ListResourcesResult, ErrorData>

async fn list_resource_templates( &self, _request: Option<PaginatedRequestParams>, _context: RequestContext<RoleServer>, ) -> Result<ListResourceTemplatesResult, ErrorData>

async fn read_resource( &self, request: ReadResourceRequestParams, _context: RequestContext<RoleServer>, ) -> Result<ReadResourceResponse, ErrorData>

async fn list_tools( &self, _request: Option<PaginatedRequestParams>, context: RequestContext<RoleServer>, ) -> Result<ListToolsResult, ErrorData>

fn get_tool(&self, name: &str) -> Option<Tool>

Get a tool definition by name.

fn ping( &self, context: RequestContext<RoleServer>, ) -> impl Future<Output = Result<(), ErrorData>> + MaybeSendFuture

fn initialize( &self, request: InitializeRequestParams, context: RequestContext<RoleServer>, ) -> impl Future<Output = Result<InitializeResult, ErrorData>> + MaybeSendFuture

fn negotiate_initialize( &self, request: &InitializeRequestParams, ) -> Result<InitializeResult, ErrorData>

Build the initialize response for request, negotiating the protocol version against [Self::supported_protocol_versions].

fn supported_protocol_versions(&self) -> Cow<'static, [ProtocolVersion]>

Return the protocol versions supported by this server.

fn discover( &self, context: RequestContext<RoleServer>, ) -> impl Future<Output = Result<DiscoverResult, ErrorData>> + MaybeSendFuture

Return this server’s discovery information.

fn complete( &self, request: CompleteRequestParams, context: RequestContext<RoleServer>, ) -> impl Future<Output = Result<CompleteResult, ErrorData>> + MaybeSendFuture

fn set_level( &self, request: SetLevelRequestParams, context: RequestContext<RoleServer>, ) -> impl Future<Output = Result<(), ErrorData>> + MaybeSendFuture

fn accepted_subscription_filter( &self, requested: &SubscriptionFilter, ) -> Option<SubscriptionFilter>

Return the subset of a requested notification filter this server accepts.

fn listen( &self, context: SubscriptionContext, ) -> impl Future<Output = Result<(), ErrorData>> + MaybeSendFuture

Run one established subscription until it is cancelled or closed gracefully.

fn subscribe( &self, request: SubscribeRequestParams, context: RequestContext<RoleServer>, ) -> impl Future<Output = Result<(), ErrorData>> + MaybeSendFuture

👎Deprecated:

resources/subscribe is legacy-only; implement accepted_subscription_filter and listen for protocol version 2026-07-28

fn unsubscribe( &self, request: UnsubscribeRequestParams, context: RequestContext<RoleServer>, ) -> impl Future<Output = Result<(), ErrorData>> + MaybeSendFuture

👎Deprecated:

resources/unsubscribe is legacy-only; subscriptions/listen is cancelled through its request lifecycle

fn on_custom_request( &self, request: CustomRequest, context: RequestContext<RoleServer>, ) -> impl Future<Output = Result<CustomResult, ErrorData>> + MaybeSendFuture

fn on_cancelled( &self, notification: CancelledNotificationParam, context: NotificationContext<RoleServer>, ) -> impl Future<Output = ()> + MaybeSendFuture

fn on_progress( &self, notification: ProgressNotificationParam, context: NotificationContext<RoleServer>, ) -> impl Future<Output = ()> + MaybeSendFuture

fn on_initialized( &self, context: NotificationContext<RoleServer>, ) -> impl Future<Output = ()> + MaybeSendFuture

fn on_roots_list_changed( &self, context: NotificationContext<RoleServer>, ) -> impl Future<Output = ()> + MaybeSendFuture

fn on_custom_notification( &self, notification: CustomNotification, context: NotificationContext<RoleServer>, ) -> impl Future<Output = ()> + MaybeSendFuture

fn get_task( &self, request: GetTaskParams, context: RequestContext<RoleServer>, ) -> impl Future<Output = Result<GetTaskResult, ErrorData>> + MaybeSendFuture

SEP-2663 tasks/get: return the current [DetailedTask] state.

fn update_task( &self, request: UpdateTaskParams, context: RequestContext<RoleServer>, ) -> impl Future<Output = Result<(), ErrorData>> + MaybeSendFuture

SEP-2663 tasks/update: accept responses to outstanding in-task input requests. Returns an empty acknowledgement on success.

fn cancel_task( &self, request: CancelTaskParams, context: RequestContext<RoleServer>, ) -> impl Future<Output = Result<(), ErrorData>> + MaybeSendFuture

SEP-2663 tasks/cancel: cooperative cancellation. Returns an empty acknowledgement; the task’s observable status may lag.
