<p>RMCP 3.0 adds support for MCP 2026-07-28. Review the <a
href="https://modelcontextprotocol.io/specification/2026-07-28/changelog">protocol
key changes</a> and the <a
href="https://github.com/modelcontextprotocol/rust-sdk/discussions/969">RMCP
3.0 migration guide</a> before upgrading from 2.x.</p>
<h2>Breaking changes</h2>
<ul>
<li><strong>Sessionless Streamable HTTP:</strong> MCP 2026-07-28 removes
protocol-level sessions: no <code>Mcp-Session-Id</code>, standalone GET
stream, DELETE-based session termination, or <code>Last-Event-ID</code>
resumption. RMCP creates a fresh handler per request, so persistent
state must live outside the handler. <code>stateful_mode</code> is
renamed to <code>legacy_session_mode</code> and now only controls older
protocol versions; custom SSE clients must also accept an optional
session ID.</li>
<li><strong>Stateless lifecycle and discovery:</strong> the 2026-07-28
protocol removes
<code>initialize</code>/<code>notifications/initialized</code>; each
request carries the protocol version and client capabilities in
<code>_meta</code>, and servers expose <code>server/discover</code>.
RMCP clients opt into this lifecycle with
<code>serve_with_lifecycle</code> and
<code>ClientLifecycleMode::Discover</code> or <code>Auto</code>; the
existing <code>serve()</code> path remains available for legacy
initialization.</li>
<li><strong>Subscriptions and removed methods:</strong>
<code>subscriptions/listen</code> replaces the standalone GET stream and
<code>resources/subscribe</code>/<code>resources/unsubscribe</code>.
<code>ping</code>, <code>logging/setLevel</code>, and
<code>notifications/roots/list_changed</code> are unavailable under
2026-07-28; RMCP retains their APIs for legacy protocol sessions.</li>
<li><strong>Multi Round-Trip Requests and result types:</strong>
<code>ServerHandler::call_tool</code>, <code>get_prompt</code>, and
<code>read_resource</code> now return MRTR-aware response enums. Manual
handler implementations and exhaustive <code>ServerResult</code> matches
must handle <code>InputRequiredResult</code>, and result models carry an
optional <code>result_type</code> for legacy wire compatibility.</li>
<li><strong>Tasks:</strong> the experimental core tasks API is replaced
by the <code>io.modelcontextprotocol/tasks</code> extension, including
new task handlers, methods, and <code>TaskManager</code> APIs.</li>
<li><strong>Rust model types:</strong> metadata is split into
<code>MetaObject</code>, <code>RequestMetaObject</code>, and
<code>NotificationMetaObject</code>;
<code>Annotations::last_modified</code> is now
<code>Option<String></code>; and tool structured content accepts
any <code>serde_json::Value</code>.</li>
<li><strong>OAuth:</strong> authorization startup is consolidated around
<code>AuthorizationRequest</code>; metadata discovery is renamed to
<code>resolve_metadata</code> and returns provenance; and custom OAuth
HTTP errors are now boxed source errors.</li>
<li><strong>Compatibility:</strong> APIs deprecated before 3.0 have been
removed, and the minimum supported Rust version is now 1.88.</li>
</ul>
