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.

Ahead on

  • Reliability, 61 against 40
  • Schema & documentation, 78 against 59
  • Agent ergonomics, 71 against 44
  • Security & auth, 63 against 54
  • Maintenance & community, 71 against 60
  • Transparency & trust, 76 against 58

Watch for

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

Secoda E

Good for A data team already on Secoda that wants an agent to read and edit catalogue metadata, lineage, documents and glossary terms, or to search the catalogue and run SQL through the local MCP server.

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

Watch for

No price is published. The three plans (Core, Premium, Enterprise) link to a sales form, and no trial or sign-up button was found on the site

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.

Secoda

The REST API reference embeds OpenAPI 3.0 definitions on every page, with llms.txt and Markdown copies, and the subscription agreement carries a 99.9 per cent uptime commitment. No price, trial or sign-up is published, no status page was found, and the public changelog stops at 28 October 2025 although self-hosted releases continue.

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

Secoda

  1. Pick the base URL by workspace region. app.secoda.co uses api.secoda.co, eu.secoda.co uses eapi.secoda.co and apac.secoda.co uses aapi.secoda.co
  2. Keep writes under 30 PUT, PATCH or POST calls a minute on entity endpoints, and back off on a 429
  3. List with /api/v1/resource/catalog and a URL-encoded JSON filter. The per-type list endpoints for tables are marked deprecated, and results stop at 10,000 resources
  4. Send at most 100 entities to /api/v1/resource/all/bulk_update/ in one request
  5. Add a trailing slash when an endpoint does not behave as expected, as the docs advise
  6. Treat an API key as the creating user. run_sql in the MCP server works only when an admin has enabled Run SQL and the user has query access to the integration

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
