Verdicts

Alation

Each API has an OpenAPI 3.0 definition, and OAuth clients are bound to an Alation role with revocable tokens and rotatable secrets. Access needs a sales contract, since no price, trial or self-serve sign-up is published. The agent SDK and local MCP server have stayed at a release candidate since 14 January 2026.

Gemini Enterprise

The assistant is callable through a GA v1 method with a 99.5 per cent SLA, OAuth through IAM, a public Discovery document and optional Model Armor screening. Seat prices weren't found on Google's pages, onboarding needs a billing account and a person, and some Gemini agent capabilities announced on 8 October are early access.

Before you call either

Alation

  1. Ask a Server Admin to register an OAuth client application with the lowest role that fits. Only admins can create one, and the secret is shown once
  2. Pin alation-ai-agent-mcp==1.0.0rc3. An unpinned install resolves to 0.12.0, which predates the catalogue search agent
  3. Call catalog_context_search_agent for catalogue questions. alation_context is deprecated and its description tells models not to call it directly
  4. Watch X-Entitlement-Usage on Aggregated Context API responses. The 2,000 free calls never reset, and a quota 429 is not retryable
  5. Page with limit and skip and follow X-Next-Page. The BI Source API uses offset, and one call returns at most 1,000 objects

Gemini Enterprise

  1. Create a Gemini Enterprise app first. StreamAssist needs its APP_ID, and the caller needs discoveryengine.assistants.assist
  2. Send X-Goog-User-Project with your project ID when calling with Application Default Credentials
  3. Pass the session name from the final stream message on the next call to keep context. Leaving it empty starts a new session
  4. Read connectorAuthErrors in the response. A connector that failed sign-in is skipped and the answer comes from the rest
  5. Use the A2A URL returned by Agent Registry verbatim. It takes the project number, not the project ID
