CAIN-42 MCPGateThe niche: MCP supply-chain security
Companies connecting agents to third-party MCP servers, and MCP server builders who want to prove their tools don't change silently.
Why this niche exists now
- MCP became the standard way to connect agents to tools.
- Tool poisoning and rug pulls are documented attack types.
- Few teams re-check tools after approval.
What people use today, and where it falls short
| What teams do today | Where it falls short |
|---|---|
| Approve once and trust | No protection after approval. |
| Manual re-review | Nobody does it. |
What makes DriftGuard (MCP pinning) different
- Field-level difference on change.
- Shadowing detection.
- Screen before approval.
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Do not quote market-size statistics on a call.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:
- How many MCP servers do your agents use?
- Any third-party ones?
- Who re-checks them?
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.
