CAIN-42 MCPGateThe niche: human-in-the-loop controls for AI agents
Companies letting agents near money, data deletion or access changes. Finance, operations and security teams want a person to approve, but ordinary approval flows are easy to reuse or fake.
Why this niche exists now
- Agents are starting to take actions with money and data.
- Buyers and auditors ask "where is the human in the loop?"
- Simple yes/no prompts get rubber-stamped and can be replayed.
What people use today, and where it falls short
| What teams do today | Where it falls short |
|---|---|
| A yes/no pop-up | Approves "something", not the exact action; easy to reuse. |
| Email approvals | Slow and impossible to bind to the action. |
| Do not let agents act | Lose the benefit. |
What makes APPROVAL different
- Bound to the exact action.
- N of M approvers.
- Single use; replay fails.
- The agent cannot approve itself.
How big is the opportunity?
Do not quote market-size statistics on a call. Most published figures are surveys or vendor estimates, and a smart buyer will ask for the source. Size the opportunity per prospect instead, with these questions:
- Which agent actions should a person approve?
- How many approvers?
- Do you use Slack?
If the honest answers are "no" or "not yet", they are not a buyer today. Note it and move on; that is good selling, not failure.
Explain the niche in 30 seconds
Companies letting agents near money, data deletion or access changes. Finance, operations and security teams want a person to approve, but ordinary approval flows are easy to reuse or fake.
APPROVAL makes a person, or several, approve the exact action an AI agent wants to take, and turns that approval into a one-use key for just that action.
Practise saying this out loud until you can do it without reading. Then say it in your own words.

Sell it together with
Buyers rarely have just one problem. When this product fits, these often fit too:
| Product | Why it goes together |
|---|---|
| BROKER | the one-shot credential underneath |
| SPEND GOVERNOR | limits on spending too |
| Black Box flight recorder | record the approved action |
Rule: open with one product. Mention a second only after the first is agreed.
