#
Resource

pub(open) trait Resource {
  fn name(Self) -> String
  fn description(Self) -> String
  fn uri(Self) -> String
  fn mime_type(Self) -> String
  async fn read(Self) -> Result[ResourceReadResult, @colmugx/mcp/protocol/types.MCPError
MCPError]
}

Core Resource trait following MCP protocol

name: Resource identifier (unique)
description: Human-readable description
uri: Resource URI (e.g., "file:///path/to/file")
mime_type: MIME type of the resource content
read: Async read operation returning resource content

#
ResourceMRTR

source

pub(open) trait ResourceMRTR {
  fn name(Self) -> String
  fn description(Self) -> String
  fn uri(Self) -> String
  fn mime_type(Self) -> String
  async fn read(Self, Json) -> Result[ResourceReadOutcome, @colmugx/mcp/protocol/types.MCPError
MCPError]
}

MRTR-aware resource trait. Implement this instead of Resource when a resources/read handler needs to suspend and ask the client for input before completing. The read method receives the full read params (after _mrtr_responses has been merged on retry).

#
ResourceContent

source

pub(all) enum ResourceContent {
  Text(String)
  Blob(String, mime_type~ : String)
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

Content type for MCP resource read results Supports text and binary blob content types per MCP spec

#
ResourceDefinition

source

pub(all) struct ResourceDefinition {
  uri : String
  name : String
  description : String?
  mime_type : String?
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

Resource metadata definition (for protocol responses) Describes a resource in the resources/list response Note: This is separate from the Resource trait which is for implementation

#
ResourceReadOutcome

source

pub(all) enum ResourceReadOutcome {
  Complete(ResourceReadResult)
  InputRequired(input_requests~ : Map[String, @colmugx/mcp/protocol/types.InputRequestEntry
InputRequestEntry], state~ : Json)
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

The result of a resources/read handler. Per the 2026-07-28 MRTR pattern, a handler may either complete normally (Complete) or request additional client input (InputRequired). On retry, the client resubmits with inputResponses and the echoed requestState; the handler receives those responses via _mrtr_responses in the read params.

#
ResourceReadResult

source

pub(all) struct ResourceReadResult {
  uri : String
  content : ResourceContent
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

Result of reading a resource Contains the URI and content of the resource

#
ResourceTemplateDefinition

source

pub(all) struct ResourceTemplateDefinition {
  uri_template : String
  name : String
  description : String?
  mime_type : String?
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)
