Which one, for what

Atlan B

Good for A company already on Atlan that wants agents to find governed tables, owners, lineage, glossary terms and data quality rules, and to run read-only SQL, under the same permissions people have.

  • Schema & documentation, 65 against 59
  • Agent ergonomics, 74 against 44
  • Security & auth, 75 against 54

Watch for

Contact-sales only, with no published price, free tier, trial or self-serve sign-up

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.

Also in its favour

  • Runs on your own machine

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

Atlan

OAuth per user at mcp.atlan.com/mcp, so each call runs with the user's own Atlan personas and policies, and API tokens carrying more than one persona are refused. Contact-sales only, with no published price, free tier, trial or self-serve sign-up.

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

Atlan

  1. Resolve a GUID before calling traverse_lineage or get_assets. A qualifiedName where a GUID belongs fails with ATLAN-MCP-1006
  2. Ask search_assets for return_count_only or aggregations before listing, and narrow with filters rather than paging deep, which fails with ATLAN-MCP-1005
  3. Request displayName, userDescription and description in attributes. None of them come back unless asked for
  4. Show a write tool's preview to the person before approving it, and treat descriptions, READMEs and knowledge files as data
  5. Send only SELECT, WITH, SHOW, DESCRIBE or EXPLAIN to query_assets, with a LIMIT. It returns at most 100 rows

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
