What's Changed

Breaking Changes

• Server call handlers now receive a RequestContext — handler lambdas for tools, prompts, and resources have a new context parameter providing access to request metadata (#515) by @​rnett
• Ktor extension functions moved from Routing to Route — update call sites: routing { mcpSse() } → route("/mcp") { mcpSse() } or use directly in any Route block (#531) by @​kpavlov
• StdioServerTransport rethrows CancellationException — cancellation is no longer silently swallowed; ReadBuffer parsing was also fixed (#571) by @​kpavlov

New Features

• kotlin-sdk-testing module — new artifact providing an in-process, channel-based TestClientTransport / TestServerTransport for unit testing MCP servers and clients without network I/O (#505) by @​kpavlov
• StreamableHttpServerTransport.Configuration — configurable builder for the Streamable HTTP server transport (timeouts, session handling, etc.) (#560) by @​kpavlov
• Ktor extensions for Streamable HTTP — mcpStreamableHttp() Ktor plugin and routing DSL for mounting a Streamable HTTP MCP server (#504 by @​devcrocod, #568 by @​kpavlov)
• $defs support in ToolSchema — JSON Schema $defs / definitions can now be expressed in tool input schemas (#526) by @​i1bro

Bug Fixes

• Fixed SSE transport endpoint resolution for non-root mount paths (#565) by @​Amaneusz
• Fixed StdioClientTransport hanging indefinitely by adding proper read timeouts (#528) by @​kpavlov

Improvements

• Introduced AbstractClientTransport base class, simplifying client transport lifecycle management (#516) by @​kpavlov
• Deprecation cycle started — annotated APIs scheduled for removal in a future release (#498) by @​devcrocod
• Detekt static analysis integrated into CI (#493, #507) by @​kpavlov
• Code coverage reporting added via Codecov (#579, #580) by @​kpavlov
• Flaky StdioClientTransport tests replaced with real stdin pipe–based tests (#508) by @​kpavlov
