Temporary credentials for AI database agents: production access should expire by default
Autonomous agents should not carry permanent database credentials around like a human service account.
Persistent credentials are convenient, but they are a poor fit for AI workflows where prompts, tools, context, and intent can vary from request to request.
For production MCP database servers, credentials should be short-lived, scoped, and tied to the specific action being performed.
Agent access should expire
If an agent is answering a reporting question, it does not need a credential that works forever. It needs a credential that works for this request, against this approved surface, under this policy, for a short window.
Temporary credentials reduce the blast radius of prompt injection, tool misuse, leaked configuration, and accidental overreach.

Scope beats trust
The safest access model is not “trust the model to behave.” It is “make unsafe behavior impossible at the credential and database layer.”
Useful scopes include database role, tenant, approved views, read-only mode, row limits, statement timeout, source network, and expiration timestamp.

Map credentials to real identity
Temporary credentials should still map back to a human, service, workflow, or customer account.
When a query appears in the audit trail, teams should know who requested it, which agent/tool executed it, which policy granted it, and when that permission expired.

Make renewal explicit
When access expires, the agent should not silently escalate or reuse a broader credential.
It should request a new scoped token or return a structured error: credential expired, approval required, scope missing, or policy denied.

Where Conexor fits
Conexor helps teams connect AI clients to databases and APIs through MCP infrastructure. The goal is not just connectivity; it is governed access with scoped credentials, approved surfaces, freshness metadata, and audit trails.
