SQL Query
Answers questions from your own database with a read-only query the agent writes and you can read back.
Connect a PostgreSQL or MySQL database, nominate the tables an agent may see, and it can answer "how many orders shipped late last week" from the data rather than from a document about the data.
The connection is read-only and the generated query is returned with the answer, so a number that looks wrong can be checked rather than argued about. The stored credential is encrypted at rest and never returned by the API.
