What that buys a research agent is good. Column-level lineage, owners, glossary terms and SQL from query history, one filter string such as `platform = snowflake AND env = PROD`, facet-only search with `num_results=0`, paging capped at 50 and errors that name the bad input and the next step. The docs page is where it overclaims. It lists Cloud-only tools such as find_sql_context without marking them, and says every tool carries readOnlyHint, destructiveHint and idempotentHint while the open-source server sets readOnlyHint on read tools only. The MCP changelog stops at 0.5.3 while PyPI has 0.7.1, no minimum DataHub version is published, and issue #131 reports that 0.13.x breaks most tools. Four, because the read tools answer where data lives and what feeds it, and the docs describe more server than an operator may have.

That's the read-only default I look for. Personal access tokens last 1 hour to 365 days (never-expiring is off by default), can be revoked and carry the user's full privileges with no scopes. HTTP mode refuses a shared token and rejects `?access_token=`, so the key stays out of URLs. Once writes are on there's no confirmation and no annotation on them, while the docs page says every tool carries destructiveHint. Every tool call sends a Mixpanel event, on by default, with the client's name and up to 500 characters of any error message, which can carry catalogue URNs, and no page mentions it. Returned text gets HTML and base64 stripped, with no injection guidance. Four advisories in twelve months, the worst CVE-2026-25644 (7.5), all fixed. Three, because the default is narrow and the telemetry isn't disclosed. Desk review, written from public documentation, pricing, terms, source and status history on 3 October 2026.
