<h2>0.15.0</h2>
<h2>Description</h2>
<p>This release makes inbound message handling concurrent after the
initialization handshake, adds SSE heartbeats and elicitation schema
validation, and fixes several Streamable HTTP response and
session-lifecycle bugs.</p>
<h3>Breaking Changes</h3>
<p><strong>Concurrent inbound dispatch</strong> by <a
href="https://github.com/devcrocod"><code>@​devcrocod</code></a> in <a
href="https://redirect.github.com/modelcontextprotocol/kotlin-sdk/pull/884">#884</a></p>
<p>Inbound messages were processed serially on the transport read loop,
so one slow or peer-awaiting handler (sampling, elicitation, roots)
blocked every later message on the connection, including the responses
and <code>notifications/cancelled</code> those handlers depend on. After
the handshake, handlers may now run concurrently; processing stays
serial during initialization.</p>
<ul>
<li><code>ProtocolOptions</code> / <code>ClientOptions</code> /
<code>ServerOptions</code> gain a <code>handlerCoroutineContext</code>
parameter (defaults to <code>Dispatchers.Default</code>). Concurrency is
bounded internally; there is no opt-out flag by design.</li>
<li><code>RequestHandlerExtra</code> is now a
<code>CoroutineContext.Element</code> and is no longer
user-constructible. It exposes <code>requestId</code>,
<code>method</code>, <code>sendRequest</code>, and
<code>sendNotification</code>, and can be read inside a handler via the
new <code>currentRequestHandlerExtra()</code>.</li>
</ul>
<pre lang="diff"><code>- val extra = RequestHandlerExtra()
+ val extra = currentRequestHandlerExtra()
</code></pre>
<p><strong>Duplicate feature names are rejected at registration</strong>
by <a href="https://github.com/devcrocod"><code>@​devcrocod</code></a>
in <a
href="https://redirect.github.com/modelcontextprotocol/kotlin-sdk/pull/883">#883</a></p>

<p><code>addTool</code>/<code>addPrompt</code>/<code>addResource</code>/<code>addResourceTemplate</code>
silently replaced an existing entry and emitted a spurious
<code>list_changed</code> notification. They now throw
<code>IllegalArgumentException</code> and leave the existing
registration intact. The batch variants
(<code>addTools</code>/<code>addPrompts</code>/<code>addResources</code>)
are all-or-nothing. To replace a feature, remove it first.</p>
<pre lang="diff"><code>- server.addTool(name = &quot;search&quot;, ...)
// silently overwrote
+ server.removeTool(&quot;search&quot;)
+ server.addTool(name = &quot;search&quot;, ...)
</code></pre>
<p><strong><code>eventStore</code> removed from
<code>mcpStatelessStreamableHttp</code></strong> by <a
href="https://github.com/devcrocod"><code>@​devcrocod</code></a> in <a
href="https://redirect.github.com/modelcontextprotocol/kotlin-sdk/pull/909">#909</a></p>
<p>The parameter was never read or written: a stateless endpoint answers
<code>GET</code> with <code>405</code>, so no stream exists to store or
replay events on. The old overload is retained at
<code>DeprecationLevel.ERROR</code> with a <code>ReplaceWith</code>
migration hint. Use <code>mcpStreamableHttp</code> when you need
resumability.</p>
<pre lang="diff"><code>  application.mcpStatelessStreamableHttp(
      path = &quot;/mcp&quot;,
-     eventStore = myEventStore,
  ) { server }
</code></pre>
<h3>Features</h3>
<ul>
<li>Optional SSE heartbeats for Streamable HTTP servers via
<code>mcpStreamableHttp(sseHeartbeatConfig = { ... })</code>, keeping
long-lived streams alive against clients that disconnect on idle.
Heartbeats stay off by default, by <a

in <a
href="https://redirect.github.com/modelcontextprotocol/kotlin-sdk/pull/761">#761</a></li>
<li>Accepted form-mode elicitation content is now validated against
<code>requestedSchema</code>; a mismatch fails
<code>createElicitation</code> with <code>McpException</code>
(<code>INVALID_PARAMS</code>) instead of reaching server code unchecked,
by <a href="https://github.com/rea9r"><code>@​rea9r</code></a> in <a
href="https://redirect.github.com/modelcontextprotocol/kotlin-sdk/pull/896">#896</a></li>
<li>The Streamable HTTP client now sends the standard
<code>Mcp-Method</code> and <code>Mcp-Name</code> POST headers, by <a

in <a

<h3>Fixed</h3>
