CallToolResult	Result payload for "tools/call".
ClientCapabilities	MCP client capability advertisement carried by RequestMeta.
CompleteRequest	Parameters for "completion/complete".
CompleteResult	Result payload for "completion/complete".
Completion	Completion values for a "completion/complete" request.
CompletionArgument	Identifies the prompt argument or resource-template variable being completed, and its current partial value.
CompletionCapability	Empty marker capability advertising "completion/complete" support (structure may grow with the spec).
CompletionContext	Optional already-resolved argument values supplied alongside a completion/complete request.
CompletionReference	Polymorphic "completion/complete" target reference (prompt or resource template).
Content	Polymorphic MCP content block (tool results, prompt messages).
CreateMessageRequest	Parameters for "sampling/createMessage", a server-to-client duplex request (MCP sampling).
CreateMessageResult	Result payload for "sampling/createMessage" (MCP sampling).
ElicitAction	Closed action set for an elicitation answer (MCP 2026-07-28 SEP-2322).
ElicitationCapability	Client elicitation capability (SEP-2322): presence on ClientCapabilities.getElicitation() signals the client understands input_required elicitation-flavored requests.
ElicitRequest	One entry of an input_required pause's inputRequests map for an elicitation sub-request (MCP 2026-07-28 SEP-2322), built by a tools/call/prompts/get/resources/read handler and placed via org.apache.juneau.rest.server.mcp.v20260728.ElicitationRequests.
ElicitResult	The end user's answer to an ElicitRequest (MCP 2026-07-28 SEP-2322), echoed back keyed by the same server-assigned id in a follow-up request's inputResponses and decoded via org.apache.juneau.rest.server.mcp.v20260728.ElicitationResponses.
ElicitSchema	Fluent builder for a restricted elicitation JSON Schema (MCP 2026-07-28 SEP-2322), producing the JsonMap consumed by ElicitRequest.setRequestedSchema(java.util.Map).
EmbeddedResourceContent	MCP resource content block (inline resource body).
GetPromptRequest	Parameters for "prompts/get".
GetPromptResult	Result payload for "prompts/get".
Icon	MCP icon descriptor (the schema's Icons.icons entry shape), used by Implementation.
Icon.Theme	Icon color-scheme hint, restricted to the schema's two legal values (MCP wire uses lowercase strings).
ImageContent	MCP image content block (base64 data).
Implementation	MCP Implementation object (BaseMetadata + Icons per the schema): required name / version, plus optional title, description, and ordered icons.
InputRequiredResult	Result of a tools/call, prompts/get, or resources/read handler pausing to request more input (MCP 2026-07-28 SEP-2322 Multi-Round-Trip Requests).
ListPromptsResult	Result payload for "prompts/list".
ListResourcesResult	Result payload for "resources/list".
ListResourceTemplatesResult	Result payload for "resources/templates/list".
ListToolsResult	Result payload for "tools/list".
LoggingCapability	Server logging capability marker (structure may grow with the spec).
McpCacheScope	SEP-2549 cache-hint authorization scope for a CacheableResult (MCP wire uses lowercase strings).
McpMethods	JSON-RPC method names used by MCP over HTTP.
McpProtocol	MCP protocol version strings carried in per-request _meta and server/discover.
McpRoutingNames	Shared SEP-2243 routing-name helper used by both the 2026-07-28 server adapter and client adapter.
ModelHint	A model family/name hint for ModelPreferences.getHints() (MCP sampling).
ModelPreferences	Model-selection preferences for CreateMessageRequest (MCP sampling).
PingResult	Result payload for "ping".
Prompt	MCP prompt descriptor (prompts/list entry).
PromptArgument	Declared argument for an MCP prompt.
PromptCapability	Server capability flags for prompts.
PromptMessage	Single message line inside GetPromptResult.
PromptReference	CompletionReference targeting a declared prompt by name.
PromptsListChangedNotification	Params for the notifications/prompts/list_changed notification.
ReadResourceRequest	Parameters for "resources/read".
ReadResourceResult	Result payload for "resources/read".
RequestMeta	Opaque per-request MCP metadata carried under the JSON-RPC params._meta property.
RequestParams<T extends RequestParams<T>>	CRTP base for MCP 2026-07-28 request params carrying optional negotiation/trace metadata under the reserved _meta wire key.
RequestParamsOnly	Metadata-only request params carrier for v2 methods whose only common params member is _meta.
Resource	MCP resource descriptor (resources/list entry).
ResourceCapability	Server capability flags for resources.
ResourceContents	Polymorphic MCP resource body (text or base64 blob).
ResourcesListChangedNotification	Params for the notifications/resources/list_changed notification.
ResourceTemplate	MCP resource-template descriptor (resources/templates/list entry).
ResourceTemplateReference	CompletionReference targeting a registered resource template by its exact URI-template string.
ResourceUpdatedNotification	Params for the notifications/resources/updated notification: a specific subscribed resource's content changed.
Result<T extends Result<T>>	CRTP base for every successful MCP 2026-07-28 result, carrying the required resultType discriminator and optional ResultMeta under the reserved _meta wire key.
ResultMeta	Opaque per-result MCP metadata carried under the JSON-RPC result._meta property.
Role	Role for PromptMessage entries (MCP wire uses lowercase strings).
RootsCapability	Client roots capability.
SamplingCapability	Client sampling capability marker (MCP sampling): presence on ClientCapabilities.getSampling() signals the client understands "sampling/createMessage".
SamplingMessage	One message in CreateMessageRequest.getMessages() (MCP sampling).
ServerCapabilities	MCP server capability advertisement returned by ServerDiscoverResult.
ServerDiscoverResult	Result payload for "server/discover".
SubscriptionFilter	Wire filter for subscriptions/listen: which notification kinds and resource URIs a client wants (see SubscriptionsListenRequest.getNotifications()), or the honored subset a server actually granted (see SubscriptionsAcknowledgedNotification.getNotifications()).
