Subject: [PATCH] build(deps): bump mcp from 1.26.0 to 1.28.1 in /engine in the
 uv group across 1 directory (#7114)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bumps the uv group with 1 update in the /engine directory:
[mcp](https://github.com/modelcontextprotocol/python-sdk).

Updates `mcp` from 1.26.0 to 1.28.1
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/modelcontextprotocol/python-sdk/releases">mcp's
releases</a>.</em></p>
<blockquote>
<h2>v1.28.0</h2>
<h2>Deprecations</h2>
<p>Two API surfaces now emit <code>DeprecationWarning</code> ahead of
their removal in v2. Nothing is removed in 1.x, and the warnings fire
only when the deprecated API is <em>called</em> - importing the modules
stays silent.</p>
<ul>
<li><strong>WebSocket transport</strong> -
<code>mcp.client.websocket.websocket_client</code> and
<code>mcp.server.websocket.websocket_server</code><code>modelcontextprotocol/typescript-sdk#1783</code></li>
<li><strong>Experimental tasks API</strong> -
<code>ClientSession.experimental</code>,
<code>Server.experimental</code>,
<code>ServerSession.experimental</code>, and the
<code>experimental_task_handlers=</code> kwarg on
<code>ClientSession</code>. Tasks (SEP-1686) were removed from the MCP
specification and are expected to return as a separate MCP
extension.</li>
</ul>
<p>If your test suite runs with <code>filterwarnings =
[&quot;error&quot;]</code> and exercises these paths, add a scoped
ignore such as <code>ignore:The experimental tasks API is
deprecated:DeprecationWarning</code> or <code>ignore:The WebSocket .*
transport is deprecated:DeprecationWarning</code>.</p>
<p>See <a
