Ask an assistant for a support case whose status you already know. Compare its answer with the source record. That small exercise makes an MCP connection easier to understand.

The exercise makes the roles visible. The assistant decides which capability to use. Its client sends a request. The MCP server performs the exposed operation and returns a result. You compare that result with the source.

Our MCP definition guide introduces the terminology. Here, the goal is to observe one workflow rather than memorize the protocol.

Choose a harmless read

Use a synthetic support case or another non-sensitive record. Write down its identifier and expected status before connecting. Avoid a task that requires the assistant to guess which record you mean.

After connecting through the provider's documented flow, confirm the account and workspace. Ask for the named record and request the source identifier in the response. Open the source independently and compare.

Check whether the response distinguishes retrieved facts from the assistant's interpretation. “Status is awaiting review” may be a stored value. “This will probably be resolved today” is an inference unless another source supports it.

Compare a sample record with the answer

Here is an illustrative fixture for the exercise, not a live support case:

{
  "case_id": "demo-case",
  "status": "awaiting_review",
  "assigned_team": "Facilities",
  "resolution_date": null
}

Use a read tool for the test system holding that fixture. Ask: “Read demo-case. Tell me its stored status and assigned team, and distinguish any missing information. Do not update it.”

A supported answer can say that the case is awaiting review and assigned to Facilities. It should say that a resolution date is unavailable. An answer promising that Facilities will finish today has added a claim the fixture does not support.

Inspect the tool result as well as the final explanation. If the result contains the correct record but the explanation adds a date, the retrieval and explanation have different outcomes. If the tool returned another identifier, investigate target selection before evaluating the prose.

You can do this comparison without knowing the protocol's message format. The important parts are the record you requested, the data that came back, and the statements made from it.

Try the missing-record case

Change the identifier to a value that does not exist in the test dataset. The workflow should report the absence clearly. It should not fill in a plausible record from memory or quietly switch to another account.

Then ask for a field that the tool does not return. A useful answer identifies the limitation. This teaches you what the connection supplies and what remains outside its scope.

You do not need to test write operations to understand this first interaction. Reads already reveal account selection, tool choice, returned structure, and the difference between data and generated explanation.

Save the result

Keep the test input, expected answer, observed answer, and date. If the service later changes, you can rerun the same case. Record an error as an error, even if the assistant offers a reasonable explanation for it.

On OBTO, you can begin by asking the connected agent to inspect the named application's graph or read a known artifact. The setup guide explains the connection. Always specify the application and domain explicitly.

The missing-record check is a useful stopping point for this exercise. You have seen a successful retrieval and the boundary of the available data without needing to change a business record.
