An AI answer can sound convincing while using the wrong definition of a business metric. As more assistants enter the workplace, engineering teams need a deliberate way to test whether those assistants understand the same business.
What changed
On September 22, 2026, Databricks announced general availability of Genie One MCP. The company describes it as a way for compatible agents to query structured and unstructured enterprise information using business context from Genie Ontology. Its announcement places the service within Unity Gateway, with policies and invocation auditing. These are vendor-described capabilities, not an independent guarantee of answer accuracy. [1]
The documentation also flags a concrete migration task: the earlier Beta endpoint is deprecated and scheduled to sunset on October 31, 2026. Teams already using that endpoint should review the current service URL and authentication requirements. The documented service enforces Unity Catalog permissions and returns source links with answers. [2]
The engineering implication
My reading of this development is that business definitions deserve the same care as an application interface. If a finance analyst, a sales manager, and a coding assistant ask about an “active customer,” the expected meaning should be explicit before anyone compares their answers.
Consider an illustrative subscription business. Sales might count accounts with an open contract, while product analytics counts accounts with recent activity. Both definitions can be useful. A dependable answer needs to identify which question is being answered, rather than silently choosing one.
A shared context layer is a possible implementation. The broader responsibility remains with the organization: agree on definitions, identify owners, and decide how changes are reviewed. A new connector cannot make those decisions on its own.
Start with a small acceptance test
I would begin with one business area and a short set of questions whose expected answers have been reviewed by its owner.
- Meaning: Ask the same question with different wording. Check that the selected metric and time period remain appropriate.
- Access: Repeat the test using accounts with different permissions. Confirm that answers and supporting evidence stay within each account’s access.
- Ambiguity: Include a question with two valid interpretations. Look for clarification or an explicit assumption.
- Change: Update a definition and check how the new interpretation reaches connected clients.
- Evidence: Have a reviewer follow the supplied sources and reproduce the important figures.
These are proposed acceptance tests, not reported product test results. Run them against the actual configuration and data you intend to use.
Measure the work around the answer
Track more than whether the response contains a plausible number. Record the time a reviewer spends checking it, the corrections required, and whether another team can repeat the analysis. Assign someone to investigate disagreements rather than letting each agent accumulate its own workaround.
For developers, this creates a concrete contribution: turn ambiguous business questions into repeatable checks. For leaders, it creates a clearer investment decision: expand access only when the organization can explain and maintain the meaning behind the answers.
Discussion question: Which business metric would cause the most confusion if two assistants interpreted it differently?
