+# Recommendation 25: formal MCP extension negotiation
+
+## Evidence
+
+MCP 2026-07-28 establishes a formal extensions framework so optional features can evolve without silently changing the protocol core.
+
+- [MCP 2026-07-28 release](https://blog.modelcontextprotocol.io/posts/2026-07-28)
+- [MCP release candidate](https://blog.modelcontextprotocol.io/posts/2026-07-28-release-candidate)
+
+## Proposed improvement
+
+Add a single extension registry describing supported versions, stability, required client capabilities, configuration gates, and fallback behavior. Route Tasks and future UI integrations through it instead of scattered feature flags.
+
+## Acceptance criteria
+
+- Unknown or incompatible extensions never alter core tool behavior.
+- Experimental extensions are disabled by default and labeled in discovery.
+- Registry snapshots are contract-tested across releases.
+- Each extension documents downgrade and removal behavior.
+
+Advertising an extension means protocol support only, not Premiere host support.
