Approval gates for AI database actions: keep suggestions fast and mutations deliberate
AI should be fast at suggesting what to do.
It should be slow and deliberate when changing production state.
That difference is the job of approval gates.
Start read-only
The safest default for AI database workflows is read-only access. Let the agent inspect approved views, summarize findings, and propose next steps without being able to mutate customer, billing, or operational data.
Read-only does not make the workflow weak. It makes the blast radius understandable.

Turn actions into proposals
When a workflow needs to change data, the first tool output should be a proposal: what would change, why, which rows are affected, which tenant or workspace is in scope, and which source data supports the decision.
The proposal should be reviewable before any mutation tool becomes available.

Use dry runs and diffs
An approval gate should show a dry-run result, not just a natural-language promise. For database changes, that means counts, sample affected rows, before/after values, and the exact operation class.
If the workflow cannot produce a clear diff, it should not proceed automatically.
Scope approval tightly
Approval should be tied to a specific action, tenant, dataset, time window, and row set. A human approving “clean up duplicates for this account import” is not approving all future duplicate cleanup across every customer.
That scope belongs in the audit log and in the tool contract.

Make refusal useful
Good approval gates do not just block. They explain what is missing: narrower scope, stronger evidence, a dry-run diff, a higher permission role, or a human owner.
That keeps the workflow moving without quietly weakening the control.

Audit the full chain
The audit trail should connect prompt, tool call, policy decision, approval event, executed operation, and final result. If something changes production data, teams need to answer who approved it, what they saw, and what actually happened.

Where Conexor fits
Conexor is MCP infrastructure for teams that want AI clients to query databases and APIs through controlled access patterns. The useful default is fast read-only analysis, with deliberate approval gates before anything can affect production state.
