Laravel MCP 1.0 Is Released

Read on laravel-news.com

Summary

Laravel MCP 1.0 ships with the 2026-07-28 protocol, adding searchable tool catalogs, cache hints, stateless request handling, and PKCE‑required OAuth with client‑metadata support. The release includes migration guidance and new headers for versioned RPC calls.

  • New MCP 2026-07-28 protocol replaces `initialize` with `server/discover` and adds version negotiation headers.
  • ToolSearch enables a small default tool list with lazy loading of additional tools via a searchable catalog.
  • Cacheable attribute and `cacheHints()` let servers specify TTL and scope; clients cache with `withCache()`.
  • Servers are now stateless; session headers removed, identify calls via custom IDs in request args or `_meta`.

Laravel developers building AI‑enabled services need to adopt the new protocol and migration steps to keep their MCP servers compatible.
