In CL 682976, Alan Donovan correctly points out that the term in the MCP spec is 'stdio', and therefore the correct capitalization is Stdio.

// The mcp package provides an SDK for writing model context protocol clients
|
|
// and servers.
|
|
//
|
|
// To get started, create either a [Client] or [Server], and connect it to a
|
|
// peer using a [Transport]. The diagram below illustrates how this works:
|
|
//
|
|
// Client Server
|
|
// ⇅ (jsonrpc2) ⇅
|
|
// ClientSession ⇄ Client Transport ⇄ Server Transport ⇄ ServerSession
|
|
//
|
|
// A [Client] is an MCP client, which can be configured with various client
|
|
// capabilities. Clients may be connected to a [Server] instance
|
|
// using the [Client.Connect] method.
|
|
//
|
|
// Similarly, a [Server] is an MCP server, which can be configured with various
|
|
// server capabilities. Servers may be connected to one or more [Client]
|
|
// instances using the [Server.Connect] method, which creates a
|
|
// [ServerSession].
|
|
//
|
|
// A [Transport] connects a bidirectional [Connection] of jsonrpc2 messages. In
|
|
// practice, transports in the MCP spec are are either client transports or
|
|
// server transports. For example, the [StdioTransport] is a server transport
|
|
// that communicates over stdin/stdout, and its counterpart is a
|
|
// [CommandTransport] that communicates with a subprocess over its
|
|
// stdin/stdout.
|
|
//
|
|
// Some transports may hide more complicated details, such as an
|
|
// [SSEClientTransport], which reads messages via server-sent events on a
|
|
// hanging GET request, and writes them to a POST endpoint. Users of this SDK
|
|
// may define their own custom Transports by implementing the [Transport]
|
|
// interface.
|
|
//
|
|
// # TODO
|
|
//
|
|
// - Support all content types.
|
|
// - Support pagination.
|
|
// - Support completion.
|
|
// - Support oauth.
|
|
// - Support all client/server operations.
|
|
// - Pass the client connection in the context.
|
|
// - Support streamable HTTP transport.
|
|
// - Support multiple versions of the spec.
|
|
// - Implement full JSON schema support, with both client-side and
|
|
// server-side validation.
