The client and server packages each bundle their own compiled copy of the class, so import it from one package consistently within a process. The codemod now rewrites Protocol and mergeCapabilities imports from shared/protocol.js to the client or server package root, like the module's other symbols, instead of dropping them with an action-required marker. 2477 8e1d2e9 Thanks @felixweinberger ! - Move the schema source modules (spec schemas, OAuth schemas, protocol constants) into @modelcontextprotocol/core and resolve them from there as a regular runtime dependency instead of bundling a private copy into each…","sponsors":[]}
