<h2>0.12.0</h2>
<h2>Description</h2>
<p>Adds sampling-with-tools per SEP-1577, JSON Schema dialect
declaration on tool schemas, server-side tool name validation, and
capability extensions; fixes SSE reconnect on the same session and stops
swallowing <code>CancellationException</code>.</p>
<h3>Breaking Changes</h3>
<p><strong>Sampling messages can carry tool calls and results
(SEP-1577)</strong> by <a
href="https://github.com/devcrocod"><code>@​devcrocod</code></a> in <a
href="https://redirect.github.com/modelcontextprotocol/kotlin-sdk/pull/718">#718</a></p>
<p><code>SamplingMessage.content</code> is now typed as a new
<code>SamplingMessageContent</code> supertype, with
<code>MediaContent</code> (text/image/audio),
<code>ToolUseContent</code>, and <code>ToolResultContent</code> as
variants. <code>MediaContent</code> still exists and now extends
<code>SamplingMessageContent</code>, so most source code that constructs
sampling messages compiles unchanged — but the binary signatures of
<code>SamplingMessage</code>, <code>CreateMessageResult</code>, and
related types have changed. <code>ClientCapabilities.sampling</code> is
also now a typed <code>Sampling</code> object instead of a raw
<code>JsonObject</code>. Recompilation is required; consumers reading
<code>sampling</code> as <code>JsonObject</code> must migrate to the
typed accessors.</p>
<p><strong><code>watchosX64</code> and <code>tvosX64</code>
Kotlin/Native targets removed</strong> by <a
href="https://github.com/devcrocod"><code>@​devcrocod</code></a> in <a
href="https://redirect.github.com/modelcontextprotocol/kotlin-sdk/pull/727">#727</a></p>
<p>These targets have been deprecated upstream. Migrate to the
corresponding ARM/simulator targets (<code>watchosArm64</code>,
<code>watchosSimulatorArm64</code>, <code>tvosArm64</code>,
<code>tvosSimulatorArm64</code>).</p>
<h3>Features</h3>
<ul>
<li>Add <code>$schema</code> field to <code>ToolSchema</code>, declaring
JSON Schema 2020-12 as the default dialect (SEP-1613) by <a
href="https://github.com/devcrocod"><code>@​devcrocod</code></a> in <a
href="https://redirect.github.com/modelcontextprotocol/kotlin-sdk/pull/696">#696</a></li>
<li>Validate tool names at registration time on the server, following
the MCP tool naming standard (SEP-986) by <a
href="https://github.com/devcrocod"><code>@​devcrocod</code></a> in <a
href="https://redirect.github.com/modelcontextprotocol/kotlin-sdk/pull/695">#695</a></li>
<li>Add <code>extensions</code> field to <code>ClientCapabilities</code>
and <code>ServerCapabilities</code> for advertising supported MCP
extensions during the initialize handshake by <a
href="https://github.com/eritscher"><code>@​eritscher</code></a> in <a
href="https://redirect.github.com/modelcontextprotocol/kotlin-sdk/pull/678">#678</a></li>
</ul>
<h3>Fixed</h3>
<ul>
<li>Validate the <code>mcp-protocol-version</code> HTTP header on
initialization requests and correct
<code>DEFAULT_NEGOTIATED_PROTOCOL_VERSION</code> to match the spec by <a
href="https://github.com/devcrocod"><code>@​devcrocod</code></a> in <a
href="https://redirect.github.com/modelcontextprotocol/kotlin-sdk/pull/697">#697</a></li>
<li>Propagate <code>CancellationException</code> instead of logging it
as an error by <a
href="https://github.com/devcrocod"><code>@​devcrocod</code></a> in <a
href="https://redirect.github.com/modelcontextprotocol/kotlin-sdk/pull/706">#706</a></li>
<li>Evict stale GET SSE stream mapping on reconnect so a new GET on the
same session is no longer silently rejected by the leftover entry from
the previous stream by <a

href="https://redirect.github.com/modelcontextprotocol/kotlin-sdk/pull/716">#716</a></li>

<h3>Maintenance</h3>
<ul>
<li>Add <code>kotlinlang</code> MCP server sample with
