Which one, for what

Alation C

Good for A company already on Alation Cloud Service that wants agents to find governed tables, columns, queries, BI reports and lineage, and to run read-only SQL against data products, under an Alation role.

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

No published price, trial or self-serve sign-up. The pricing address redirects to a sales form

Collibra B

Good for An organisation that already runs Collibra and wants an agent to look up assets, glossary terms, lineage and data quality, or to write assets and classifications under a governed role.

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.

Collibra

Each REST API has an OpenAPI 3.0 definition, the developer portal publishes llms.txt and Markdown pages, and every MCP tool carries read-only and destructive annotations. Access needs a sales contract, since no price, trial or self-serve sign-up is published, and no general API rate limit was found in the reviewed documentation.

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

Collibra

  1. Ask a Collibra administrator to register an OAuth application. Integration applications use client credentials, and MCP clients need a user application with a redirect URI
  2. Reuse each access token for its 5 minutes. The token endpoint answers 429 once a client drains its pool of 100 tokens, refilled at 30 a minute
  3. Page large reads with cursor= and sortField=ID. Cursor and offset parameters cannot be combined, and Search API limit plus offset cannot exceed 10,000
  4. Keep Import API files to 10,000 assets or fewer and run at most 8 imports at once. Retry a job that fails on a concurrency error
  5. Expect discover_data_assets and discover_business_glossary to consume Collibra Units and to need the dgc.ai-copilot permission. Use search_asset_keyword for free keyword search
