## 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.

Ahead on:
- Reliability, 67 against 53
- Agent ergonomics, 74 against 67
- Transparency & trust, 73 against 68

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

### Dust (B)

Good for: A team that already works in Dust and wants an outside agent to search its spaces, read documents and call its agents with a user's own access.

Ahead on:
- Schema & documentation, 75 against 65
- Payments & pricing, 20 against 0
- Maintenance & community, 86 against 80

Also in its favour:
- Open source

Watch for: Programmatic usage has no free credits. It draws only on the workspace credit pool, which Free seats cannot use

## 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.

**Dust.** The whole platform is MIT on GitHub, with a public OpenAPI document of 68 operations, llms.txt and a remote MCP server that acts with the signed-in user's access. API calls that run agents draw only on a paid workspace credit pool, and the terms of service could not be read.

## 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

### Dust

1. Use `https://eu.dust.tt` for a workspace in the EU region and `https://dust.tt` otherwise, for both the API and the MCP server
2. Connect an MCP client by OAuth and send the `resource` parameter in authorisation and token requests. API keys do not work on the MCP server
3. Expect HTTP 429 with type `rate_limit_error` when the credit pool, the programmatic monthly cap or the key's spend cap is exhausted. Retrying will not help
4. Call `GET /api/v1/w/{wId}/search` with `limit` (1 to 100, default 25) and `cursor`, or a data source view's search with `top_k`
5. Keep document upserts under 120 a minute per workspace
