Semantic Code Search does not include Premium plans

Context

A customer that should be eligible for Semantic Code Search is getting the following error when invoking it:

Error: Tool execution failed: Unable to perform semantic search, Project <project_path> has no embeddings - pluse use another tool or context source

Findings

From @arturoherrero on slack thread:

The Semantic Code Search is documented as supporting Premium + Ultimate tiers, but the code only enables it for Ultimate customers. Premium customers are incorrectly filtered out?

namespace = Project.find_by_full_path(project_path).root_namespace

  • ✅ Premium subscription: true

  • ✅ Not expired: true

  • ✅ Duo features enabled: true

  • ✅ Experiment features enabled: true

  • with_ai_supported_plan

    puts "Current check (ai_features): #{Namespace.with_ai_supported_plan(:ai_features).where(id: namespace.id).exists?}"

    ❌ Has AI plan (ai_features): false    # ai_features is Ultimate-only

    puts "Proposed fix (mcp_server): #{Namespace.with_ai_supported_plan(:mcp_server).where(id: namespace.id).exists?}"

    ✅ Has AI plan (mcp_server): true      # mcp_server is Premium+

def self.valid_saas_namespaces
  Namespace
    .group_namespaces
    .top_level
    .with_ai_supported_plan              # ❌ Defaults to :ai_features (Ultimate-only) https://gitlab.com/gitlab-org/gitlab/-/blob/a6531098b721c826b7b4be84edaef41827e3a5d6/ee/app/models/gitlab_subscriptions/features.rb#L224
    .merge(GitlabSubscription.not_expired)
end

Proposal

From @arturoherrero on slack thread

A possible fix?

def self.valid_saas_namespaces
  Namespace
    .group_namespaces
    .top_level
    .with_ai_supported_plan(:mcp_server)  # ✅ Premium + Ultimate
    .merge(GitlabSubscription.not_expired)
end

From @partiaga on slack thread

I think it's time to introduce a feature specific to semantic_code_search, and have that be eligible for PREMIUM and ULTIMATE.
