## 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 30
- Schema & documentation, 78 against 56
- Agent ergonomics, 71 against 37
- Security & auth, 63 against 56
- Maintenance & community, 71 against 36
- Transparency & trust, 76 against 63

Also in its favour:
- Runs on your own machine

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

### Lens (Thought Industries) (E)

Good for: Companies that want customers and AI tools to get one answer from their public docs, help centre and courses, with source groups to split audiences.

Ahead on:
- Payments & pricing, 30 against 0

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: Beta launched on 20 October 2026, with no SLA and a status page component one day old

## 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.

**Lens (Thought Industries).** Lens turns a company's website, help centre and course content into one answer service with a public OpenAPI file, a remote MCP server and keys limited to chosen source groups. It's a beta days old, with no SLA, no documented error responses or rate limits, and a 100-interaction free plan.

## 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

### Lens (Thought Industries)

1. Send the Lens key as `Authorization: Bearer <key>` and POST JSON `{"question": "..."}` (1 to 2,000 characters) to https://api.lens.thoughtindustries.com/v1/ask
2. Pass the returned `sessionId` on follow-up questions to keep context
3. Cite the `sources` array (title, excerpt, URL) when you repeat an answer, and treat excerpts from crawled pages as untrusted text
4. Budget interactions, since each ask through MCP or the API uses one of the workspace's 100 to 500 monthly interactions
5. Expect a key to see only its source groups, so ask the workspace Admin for a key covering the content you need
