This CL contains an minimal prototype of an MCP SDK, using the "new" jsonrpc2_v2 package (similar to x/exp/jsonrpc2). Much is still yet to do, but this initial version addressed the following aspects: - Support for newline delimited JSONRPC2 framing, and message logging. - A generated protocol package, containing type definitions to be used in transport. - A minimal jsonschema package to be used for both reading the MCP spec, and for serving Tool input schemas. - A transport abstraction, and two transport implementations: stdio, and local (for testing). - Client and Server types, to be configured with features and then connected using their Connect methods, which return (respectively) a ServerConnection and ClientConnection object. - A minimal binding API for tools. A catalog of things not yet done is in doc.go, but we should review this CL eagerly, as it contains the fundamental building blocks of an eventual SDK. It is the intention that this package is more-or-less standalone, as it may eventually be carved out into a separate repository. As such, its only dependency within x/tools is jsonrpc2_v2, and the only change required to that package is to expose a callback when the connection is closed.
