Why this signal matters
MCP TypeScript SDK releases published @modelcontextprotocol/server-legacy@2.0.0. This release-watch entry was generated from the project's official GitHub release feed and is kept separate from human-reviewed editorial analysis. Release notes: Minor Changes - 2477 (https://github.com/modelcontextprotocol/typescript-sdk/pull/2477) 8e1d2e9 (https://github.com/modelcontextprotocol/typescript-sdk/commit/8e1d2e92b1720d2520122b3a5f20ea084edaf3c4) Thanks @felixweinberger (https://github.com/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 package. An application importing more than one of the packages now evaluates a single shared schema graph with shared object identity. @modelcontextprotocol/core gains a ./internal subpath (SDK-internal contract; may change in any release) and the four packages now version together.
